150 Actual Biology Research Paper Topics


Biology is one of the most fascinating fields of study these days. There are so many incredible developments going on. If you want to be a biologist or scientist in the future, there is no better time to start than right now.

One of the best ways to dip your toes into the field is by writing a research paper. Before you do that, you need to know what are some good biology research topics. They should be suitable topics for biology students rather than cutting-edge researchers.

What Is Biology? What Topics Might Biologists Study?

Biology is simply the study of living things. That includes you and me, as well as the plants, animals and everything bigger and smaller all around us. It is about studying how living things grow, develop and interact with each other. Biology research topics encompass all these and more.

It is impossible to list every single topic or sub-field Biologists might study. But if you want some interesting biology topics for research, you are certainly in the right place. There are many exciting biology topics to research or to use in projects.

Plant Biology research topics are all about studying the plants around us – how they exist as a part of the ecosystem, their life cycle, what kind of resources they can give us, how we can preserve them from climate change, and so on.

Human Biology research topics are all about us. These topics focus on different parts of the body such as the human brain, the human immunological system, the nervous system, etc. They include studying genetic disorders and DNA modification in humans.

Environmental biology research topics are also quite important. Climate changing is becoming a bigger threat every day. By studying environmental biology topics 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. It’s important to know about them so we can understand what makes us sick and how to combat it.

Molecular biology research 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.

How to Choose Topic for Biology Research Paper?

You have probably heard of different subfields of biology before – Botany, Zoology, Microbiology, Immunology, Neurobiology, etc. There are dozens more. Any biology research paper topics you pick should try to be relevant under one or more fields.

Biology research is extremely important to today’s world. By doing research, we can learn more about genetic disorders, immune disorders, mental health, natural disease resistance and other things. Knowing about each of these could possibly save lives in the future.

The first thing to do when choosing biology research paper topics is to find one that is interesting to you. Passion is very important in research, after all.

Next, study up on 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, then the paper could end up too short. Analyze the topic and how to approach it so you can strike a balance between the two.

Then it’s time to learn about 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.

When choosing a topic, make sure it has plenty of resources available. A research paper on xenobiology or cutting-edge nanobiology might sound interesting, but you may have a hard time getting data and resources for those unless you are a researcher at a government lab or something.

Data, resources, hard numbers and statistics are all invaluable to writing a paper about these biology topics.

That is why we have selected a range of biological topics. The topics on this list are all hopefully interesting biology research topics you could write a great paper on.
