Biology is the study of living organisms that covers their origin, anatomy, physiology, development, evolution, and behavior. A biologist could study a wide array of options, such as animal and plant cell structure, human DNA, neurobiology, stem cell treatments, immunology, hormones, and much more.
Biology is often called the science of life. From bacteria to whales, biologists study all kinds of organisms. Have you ever wondered why bees dance? Or how can chickens be the closest modern relatives to dinosaurs? The buzzing world is full of complex wonders like these. That’s why it’s so easy to find a biology research topic of your liking.
If you need to craft a biology essay, this article is for you. Here you can learn about research areas and fields in biology. Besides, you will find 120+ interesting biology topics to write about.
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.

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.
