What Is Biology? What Topics Might Biologists Study?

Biology is simply the study of everything that has a form of life. It includes investigations on plants, animals, and everything found in the environment. It is about studying how life forms grow, develop, and interact with each other. Biology essay topics for research encompass all these and more.

This science uncovers many fields where various life forms are studied. It makes sense to look through these fields to help you decide which suits you the best.

Plant Biology research topics are about studying the plants around us. They disclose information about their existence as a part of the ecosystem, their life cycle, resources they can give us, their ability to preserve them from climate changes, and so on. There are many ideas to choose from, but you must focus on a specific one.

Human Biology research topics are all about us. These topics focus on different body parts, such as the human brain, the human immunological system, the nervous system, etc. In addition, you can discuss DNA modifications in humans and explain why genetic disorders occur in your research projects. Various cell research is also common today.

Biology research topics on the environment are in great demand too. For example, climate change is becoming a more significant threat every day. By studying environmental topics in biology for projects and research, we can come up with ways to combat them and preserve ecosystems.

Microbiology research topics delve into things we can’t see. There are trillions of microbes and bacteria all around us. Knowing about them is essential to understanding what makes us sick and how to fight against them. All microbiology research paper topics are pretty complicated yet very engaging to include in your paper research.

Molecular biology topics dive even deeper into the level of atoms and molecules. The various medicines and drugs we take were all created through molecular-biology research. It is one of the areas full of ideas, but there is yet to be much evidence. Science is advancing in this realm but still needs a lot of time. Topics of molecular biology will need days for research only.

Keep in mind that there are more ideas and variations of this science. We offer more examples in further sections of the article about developmental biology, marine biology, evolutionary biology, etc. Explore them and make your writing appealing and meaningful in the eyes of a professor.

How to Choose a Topic for Biology Research Paper?

When choosing a biology project topic, you must be aware of one or more fields of science. Biology research is critical to the present world. By doing research, we can learn more about genetic disorders, immune disorders, mental health, natural disease resistance, etc. Knowing about each of these could save lives in the future.

For those who may not have the time or resources to do their own research, there are research paper writing services that can provide assistance with the project. And we are always here to help you find your own topic among interesting biology research topics. Here we prepared some useful tips to follow.

  • Tip 1: The level of interest matters Pay attention to one that interests you, and you might have ideas on how to develop the topic. Passion is fundamental in research, after all.
  • Tip 2: Explore the topic Try to narrow things down a bit. If the topic is too broad, you may not be able to cover all aspects of it in one research paper. If it is too narrow, the paper could end up too short. Analyze the topic and the ways to approach it. By doing so, you can strike a balance between the two.
  • Tip 3: Discover the recent developments To make your research paper touchable with the present day, you must explore the latest developments in the field. You can find out what kind of research has been done recently by looking at journals. Check out research papers, topics, research articles, and other sources.
  • Tip 4: Ensure to get enough resources When choosing a topic, make sure it has plenty of resources available. For example, a research paper on xenobiology or cutting-edge nanobiology might sound attractive. Still, you might have difficulties getting data and resources for those unless you are a researcher at a government lab. Data, resources, complex numbers, and statistics are all invaluable to writing a paper about these topics.

That is why we have selected a range of biological topics. The topics on this list are all hopefully exciting topics for research you could write an excellent paper on. We should also add that easy biology topics to research are rare, and a writer usually needs days to prepare and start writing. Yes, biology research topics for high school students are a bit easier, but still, they need time to explore them.

On the other hand, biology research topics for college students are far more complex and detailed. Some people prefer evolutionary biology research paper topics, and we can agree with this claim. These research areas do have a lot of potential and a lot of data to support the claims. Others prefer cell biology research topics that are a bit specific and fun. Anyway, with this article's list of easy biology research topics, you will surely find the one matching your interest.

For those who may not have the time or resources to do their own research, there are provide assistance with the project.

How to Choose Biology Research Topics?

To choose a good biology research topic, we recommend following these general tips:

  • Avoid general topics - The key to choosing a biology research paper topic is ensuring it doesn’t have to do with something general. If your topic is too broad, you may not be able to go into detail, which is crucial for showcasing your knowledge. The sheer amount of information on a broad topic might also overwhelm both you and your reader.
  • Avoid too narrow topics - If your focus is too narrow, you may not find enough sources to write a paper. The reader may become disinterested as well if there’s no room for overarching questions.
  • Explore different ideas - Find several topics that interest you before sifting through recent biology research papers. That’s how you’ll get a better idea of the current trends and narrow down your focus to a single topic and idea. There are tons of scholarly articles online that are available to the public.
  • Conduct thorough research - Just like chemistry research paper topics , for example, biology research topics must be based on hard scientific evidence. So, once you’ve picked a single idea, conduct preliminary research to see if there are enough relevant and reliable sources you could use, along with hard data, to support all your claims.
  • Make sure your research will derive new findings - The topic you choose and how you want to go about it should add value to the scientific community. So, avoid topics that can’t add anything new to the table.

What Is a Good Biology Research Paper Topic?

A good biology research paper topic is one that reveals something interesting that can offer a whole new perspective on life. It should be thought-provoking, attention-grabbing, and relevant to the community.

It doesn’t matter what it’s about - humans, animals, plants, ecology, etc. - as long as it addresses something from a new perspective, makes a new discovery, shows a link between two organisms or phenomena, or potential to lead to a scientific breakthrough.

It’s all about tackling an area or topic that holds great potential and can help us understand life and living organisms better.

biology research topics

Every student studying something related to biology — botany, marine, animal, medicine, molecular or physical biology, is in an interesting field. It’s a subject that explores how animate and inanimate objects relate to themselves. The field unveils the past, the present, and what lies in the future of the relationship between the living and nonliving things. This is precisely why you need custom and quality biology topics for your college and university essay or project. It’ll make it easy to brainstorm, research, and get to writing straight away. Before the deep dive, what is biology?

What Is Biology?

Everyone knows it’s the scientific study of life, but beyond that, biology facilitates the comprehension of living and nonliving things. It’s a branch that explores their anatomy, behavior, distribution, morphology, and physiology.

For example, it understands how genes are classified and constituted into generations. It encompasses various branches, including botany, medicine, genetics, ecology, marine biology, zoology, and molecular biology. Here are what some of these mean:

Botany: This study of plants examines their structure, physiology, ecology, economic importance, and distribution, among others. It also deals with their biochemical processes, properties, and social interactions between plants. It extends to how plants are vital for human life, survival, and growth and how they play a significant role in stabilizing environmental health. Zoology: Zoology studies animal behavior, brain, structure, physiology, class, and distribution. It’s the general study of the lives of both living and extinct animals. It explains animal classification, the animal kingdom, evolution, habitat, embryology, and life span. Physiology: Physiology deals with the daily functions of the human body: How it works and the factors that make it work. It examines molecular behavior, the chemistry and physics behind locomotion, and how the cells in the living organisms’ body function. It helps understand how humans and animals get sick and what can be done to alleviate pain. Microbiology: Dealing with microorganisms, it examined how viruses, algae, fungi, bacteria, protozoa, and slime molds become parts of human life. They’re regarded as microbes, which play substantial roles in the human biochemical processes, including climate change, biodegradation, biodeterioration, food spoilage, biotech, and epidemiology. Marine Biology: This is the scientific study of organs in the sea. It understands their family classification, how they survive, and what makes wild marine animals different from domesticated and consumable ones. It also explores their interaction with the environment through several processes. The marine biologist studies marines in their natural environment, collects data on their characteristics, human impact on their living, and how they relate with themselves.

Now that you know all these, here are some custom biology topics to research for your university or college essay and paper.

History of Biological Science

The history of biology begins with the careful observation of the external aspects of organisms and continues with investigations into the functions and interrelationships of living things.

The fourth-century B.C. Greek philosopher Aristotle is credited with establishing the importance of observation and analysis as the basic approach for scientific investigation. He also organized the basic principles of dividing and subdividing plants and animals, known as classification. By A.D. 200, studies in biology were centered in the Arab world. Most of the investigations during this period were made in medicine and agriculture. Arab scientists continued this activity throughout the Middle Ages (400–1450).

Scientific investigations gained momentum during the Renaissance (a period of rebirth of art, literature, and science in Europe from the fourteenth to the seventeenth century). Italian Renaissance artists Leonardo da Vinci (1452–1519) and Michelangelo (1475–1564) produced detailed anatomical drawings of human beings. At the same time, others were dissecting cadavers (dead bodies) and describing internal anatomy. By the seventeenth century, formal experimentation was introduced into the study of biology. William Harvey (1578–1657), an English physician, demonstrated the circulation of the blood and so initiated the biological discipline of physiology.

So much work was being done in biological science during this period that academies of science and scientific journals were formed, the first being the Academy of the Lynx in Rome in 1603. The first scientific journals were established in 1665 in France and Great Britain.

The invention of the microscope in the seventeenth century opened the way for biologists to investigate living organisms at the cellular level— and ultimately at the molecular level. The first drawings of magnified life were made by Francesco Stelluti, an Italian who published drawings in 1625 of a honeybee magnified to 10 times its normal size.

During the eighteenth century, Swedish botanist Carolus Linnaeus (1707–1778) developed a system for naming and classifying plants and animals that replaced the one established by Aristotle (and is still used today). Based on his observations of the characteristics of organisms, Linnaeus created a ranked system in which living things were grouped according to their similarities, with each succeeding level possessing a larger number of shared traits. He named these levels class, order, genus, and species. Linnaeus also popularized binomial nomenclature, giving each living thing a Latin name consisting of two parts—its genus and species— which distinguished it from all other organisms. For example, the wolf received the scientific name Canis lupus, while humans became Homo sapiens.

In the nineteenth century, many explorers contributed to biological science by collecting plant and animal specimens from around the world. In 1859, English naturalist Charles Darwin (1809–1882) published The Origin of Species by Means of Natural Selection, in which he outlined his theory of evolution. Darwin asserted that living organisms that best fit their environment are more likely to survive and pass their characteristics on to their offspring. His theory of evolution through natural selection was eventually accepted by most of the scientific community.

French microbiologist and chemist Louis Pasteur (1822–1895) showed that living things do not arise spontaneously. He conducted experiments confirming that microorganisms cause disease, identified several disease-causing bacteria, and also developed the first vaccines. By the end of the nineteenth century, the germ theory of disease was established by German physician Robert Koch (1843–1910), and by the early twentieth century, chemotherapy (the use of chemical agents to treat or control disease) was introduced. The use of antibiotics became widespread with the development of sulfa drugs in the mid-1930s and penicillin in the early 1940s.

From the nineteenth century until the end of the twentieth century, the amount of research and discovery in biology has been tremendous. Two fields of rapid growth in biological science today are molecular biology and genetic engineering.

The 10 Most Interesting Biology Research Topics

Turn Your Dreams Into Reality

Take our quiz and we'll do the homework for you! Compare your school matches and apply to your top choice today.

If you ask any biology expert whether their research subject is interesting, of course they'll say yes. Even moss can be fascinating when you look at it under a magnifying glass. Some biology topics are easier for non-biologists to get more excited about than others, though.

Whether you're looking for a research topic for a college paper or an area to specialize in if you're majoring in biology , here are some of the most interesting things going on in the biology world right now.

1. CRISPR and Genetic Engineering

Normally, we think of our DNA as being set in stone. But what if it isn't? What if you could literally change your DNA?

Scientists have only recently figured out how to use CRISPR to edit DNA sequences.

That's what CRISPR promises. Short for Clustered Regularly Interspaced Short Palindromic Repeat, CRISPR is essentially a search and cut/paste function all rolled into one, but for DNA. This organizational pattern appears naturally in bacteria, and scientists have only recently figured out how to use it to edit DNA sequences in other organisms — including humans.

CRISPR is taking off in a big way due to its staggering potential. Imagine if you could cure genetic diseases, change your eye color, or make people permanently resistant to tricky viruses like HIV. It's easy to see the potential for life-changing benefits and great harm at the same time, and that's why there's currently so much excitement about CRISPR.

2. Epidemiology and Coronavirus

Epidemiology is the study of how diseases spread in populations. Now that we're in one of the largest pandemics in recent memory , it's easy to see why this is such an interesting topic. Finding a vaccine and ways to prevent the spread of COVID-19 has become the single greatest all-hands-on-deck effort of our time.

Even before the coronavirus outbreak, epidemiology intrigued scientists. Epidemiologists are often thought of as a modern-day Indiana Jones because they work in remote jungles and chase dangerous and terrifying diseases like Ebola all around the world.

If you haven't heard of prions, make sure you're sitting down. These infectious-disease-causing agents are responsible for things like mad cow disease, chronic wasting disease, and (possibly) Alzheimer's disease .

They work by essentially turning brains into Swiss cheese. Prions aren't fully living organisms like bacteria or parasites; rather, they're bits of misshapen proteins that cause other proteins to become deformed in a chain reaction until the brain is literally full of holes.

Because prions aren't truly alive, there's no real way to "kill" them. As a result, they can persist in the environment and stay contagious for years, even surviving normal sterilization techniques at hospitals and labs. Scientists are trying to understand how prions work on a basic level, and how to prevent them from accumulating in the environment and causing disease.

4. Climate Change

Despite what some governments might think, climate change has emerged as one of the most pressing issues of our time. Scientists have measured the chemical signal from greenhouse gases and determined that it's a direct result of human industrial activity .

Climate change is one of the most pressing issues of our time.

The battle against climate change seems daunting. First, scientists must convince the general public — especially legislators — that the phenomenon exists. Then, there's the huge task of identifying possible solutions.

With global consequences, climate change scientist is a job that's not likely to end within our lifetimes, meaning there's plenty of room for new environmental specialists.

5. Cancer Biology

About 2 out of every 5 people in the U.S. will develop cancer in their lifetimes, according to the National Cancer Institute .

What scientists are learning now is that "cancer" is more of an umbrella term for many different diseases that all have the same outcome: uncontrolled cell growth and, eventually, death. It's not as simple as finding the solution to one disease because cancer is actually many diseases, each with its own cause, progression, outcome, and treatment.

Now that scientists know more about cancer, the path forward is clear: More research on each type of cancer is needed before we can understand and ultimately eradicate it.

6. Behavioral Economics

You know you should pay off your debt and save more money , but most of us don't do that. Why not? And what are scientifically backed ways that we can learn how to do these things?

Behavioral economics is about how your biology affects both your finances and happiness.

This is what the captivating new field of behavioral economics aims to answer. The multidisciplinary approach combines two vastly different areas — economics and behavior — in an effort to understand how humans can live happier lives.

One major paper on the topic linked peak happiness levels to an income of around $75,000. Yet in 2018, the median household income fell short of that mark by almost $15,000 . In other words, behavioral economics is the study of how your biology affects your finances and happiness.

7. Endangered Species Recovery

It's estimated that up to 8,700 species go extinct every year. At this rate, we're due for the biggest mass extinction since the time of the dinosaurs.

And it's not just pandas, caribou, and other cuddly things that are dying out — many of the smaller organisms that keep the ecosystem running smoothly are disappearing, as are "ugly" animals that are still very important to the environment.

Even though the public is generally supportive of recovery efforts, the government conservationists responsible for this work almost always face budget shortfalls. If you're willing to deal with the challenges of working as a wildlife biologist , it can be a highly rewarding career.

8. Astrobiology

We haven't discovered life outside of Earth — yet. Astronomers have crunched the numbers and found overwhelming support for the idea that somewhere out in the cosmos, there's a good chance life exists. Astrobiologists study what those life forms might look like, such as how they reproduce and survive.

Even before we find extraterrestrial life, though, there's plenty of work for astrobiologists to do now with preparing current Earth-dwellers for when we'll eventually jet off this planet. Astrobiologists study things like how gravity affects astronauts' bones, how plants grow in space, and what happens to circadian rhythms on planets with a different day/night cycle.

9. Synthetic Biology

Evolution hasn't created the perfect version of everything yet, but it's come pretty close in a lot of areas. There are lessons we can learn about all kinds of things from the natural world, such as how to design the quietest aircraft by studying owl feathers .

Other synthetic biologists focus on how to redesign organisms to perform useful tasks. For example, you could specialize in engineering microorganisms to produce medical-grade insulin or help with bioremediation efforts in polluted areas.

10. Epigenetics

What if I told you that the stresses your grandparents endured, such as famines, wars, and inequality, could still be affecting you today through your genes ? It's not such a far-fetched idea when you consider the field of epigenetics.

Epigenetics is the study of how genes are inherited and whether they're active or inactive.

Epigenetics is the study of how genes are inherited in either a switched-on or switched-off state. Even though you inherit certain genes from your ancestors, some might not actually be "turned on" despite being present in your DNA. Just like a light switch, genes that have been "turned off" are technically inactive.

Epigenetics is a relatively new field of biology that adds a whole new layer of complexity to the already exciting realm of genetic research.

A scientist gazes at a screen displaying color-coded genetic patterns, the images reflecting off his glasses.

Never Stop Learning

These 10 biology topics are some of the hottest areas in scientific research today, but don't limit yourself — there's more than enough knowledge to satisfy a curious mind in any field. You might just have to look a little closer under the microscope to find an entirely new world.

General Education


One of the hardest parts of writing a research paper can be just finding a good topic to write about. Fortunately we've done the hard work for you and have compiled a list of 113 interesting research paper topics. They've been organized into ten categories and cover a wide range of subjects so you can easily find the best topic for you.

In addition to the list of good research topics, we've included advice on what makes a good research paper topic and how you can use your topic to start writing a great paper.

What Makes a Good Research Paper Topic?

Not all research paper topics are created equal, and you want to make sure you choose a great topic before you start writing. Below are the three most important factors to consider to make sure you choose the best research paper topics.

#1: It's Something You're Interested In

A paper is always easier to write if you're interested in the topic, and you'll be more motivated to do in-depth research and write a paper that really covers the entire subject. Even if a certain research paper topic is getting a lot of buzz right now or other people seem interested in writing about it, don't feel tempted to make it your topic unless you genuinely have some sort of interest in it as well.

#2: There's Enough Information to Write a Paper

Even if you come up with the absolute best research paper topic and you're so excited to write about it, you won't be able to produce a good paper if there isn't enough research about the topic. This can happen for very specific or specialized topics, as well as topics that are too new to have enough research done on them at the moment. Easy research paper topics will always be topics with enough information to write a full-length paper.

Trying to write a research paper on a topic that doesn't have much research on it is incredibly hard, so before you decide on a topic, do a bit of preliminary searching and make sure you'll have all the information you need to write your paper.

#3: It Fits Your Teacher's Guidelines

Don't get so carried away looking at lists of research paper topics that you forget any requirements or restrictions your teacher may have put on research topic ideas. If you're writing a research paper on a health-related topic, deciding to write about the impact of rap on the music scene probably won't be allowed, but there may be some sort of leeway. For example, if you're really interested in current events but your teacher wants you to write a research paper on a history topic, you may be able to choose a topic that fits both categories, like exploring the relationship between the US and North Korea. No matter what, always get your research paper topic approved by your teacher first before you begin writing.

113 Good Research Paper Topics

How to Write a Great Research Paper

Even great research paper topics won't give you a great research paper if you don't hone your topic before and during the writing process. Follow these three tips to turn good research paper topics into great papers.

#1: Figure Out Your Thesis Early

Before you start writing a single word of your paper, you first need to know what your thesis will be. Your thesis is a statement that explains what you intend to prove/show in your paper. Every sentence in your research paper will relate back to your thesis, so you don't want to start writing without it!

As some examples, if you're writing a research paper on if students learn better in same-sex classrooms, your thesis might be "Research has shown that elementary-age students in same-sex classrooms score higher on standardized tests and report feeling more comfortable in the classroom."

If you're writing a paper on the causes of the Civil War, your thesis might be "While the dispute between the North and South over slavery is the most well-known cause of the Civil War, other key causes include differences in the economies of the North and South, states' rights, and territorial expansion."

#2: Back Every Statement Up With Research

Remember, this is a research paper you're writing, so you'll need to use lots of research to make your points. Every statement you give must be backed up with research, properly cited the way your teacher requested. You're allowed to include opinions of your own, but they must also be supported by the research you give.

#3: Do Your Research Before You Begin Writing

You don't want to start writing your research paper and then learn that there isn't enough research to back up the points you're making, or, even worse, that the research contradicts the points you're trying to make!

Get most of your research on your good research topics done before you begin writing. Then use the research you've collected to create a rough outline of what your paper will cover and the key points you're going to make. This will help keep your paper clear and organized, and it'll ensure you have enough research to produce a strong paper.
