200+ best biology research topics for college students

Biology research assignments are technical and daunting. It is common for students to experience challenges while writing them. Fascinating biology research topics need to be attention-grabbing, engaging, and academically appropriate. A great topic sets the foundation of a scientific argument that contributes valuable knowledge to science.

This article contains more than 200 great research topics on biology that will help you in your research. You do not need to pick a topic and write on it, but rather you can use it to build your idea.

How to write a biology research paper

If you are reading this, you probably are searching for the importance of having a good writing strategy for your biology paper. Before writing your research  paper, plan properly and have a strategic reflection on your work. This will enable you to write quality work and save time while writing your paper.

Since biology is a science, there are two ways to write your scientific paper. Universal and individual scientific methods:

  1. Universal scientific methods

A universal type research paper has the following characteristics:

  1. Modeling – a technique when a certain viewpoint of an objective is presented, the scientists gather evidence to back up their standpoint.
  2. Observation – research is conducted through observation and measurement of an objective. Data verification is obtained through experiment repetition and observation.
  • Experiment – a technique that provides solutions to a problem by providing numerical and observed results from experiments.
  1. Individual scientific methods

An individual type research paper is written through:

  1. Observing a natural phenomenon
  2. Making a hypothesis
  • For a true hypothesis, find more evidence to back it up
  1. For a false hypothesis, change your angle of research or create a new hypothesis
  2. Conclude your findings

Structure of a biology research paper

A good research paper aligns the writers thought process consistent with the objectives of the paper. Here is a simple guide to drafting your paper:

1. Title

The title of your paper should be a question or an introductory statement based on the topic of the paper. It should be clear and concise to the reader.

2. Abstract

This is a summary of the contents of your paper. The objective of the paper should be clearly defined in the abstract. The reader should have a vivid idea of what the paper entails and the results of the study.

3.Introduction

An opening discussion is a chance for the author to explain what the paper is trying to solve. The introduction may contain the thesis statement for the paper.

4.Methods

Methods describe how tests were carried out and the procedure of the experiment. The procedural steps should be directive, short, and clear.

5.Results

This section contains the results of the experiment or any calculated data findings. The results can be figure-based or observational.

6.Discussion

Discussion is an argument by the author on how the results affect or are relevant to the study. You may highlight the limitations of the study. Additionally, the author may also discuss their opinions and make recommendations.

7.Bibliography

This contains references to all cited works. It is an important part of your research paper as it depicts the originality of your work.

How to choose a topic for biology research paper

Choosing a research topic is a daunting task for any student since you are expected to write about something new. At the same time, you are not expected to make any radical discovery, especially in the earlier years of your study. The following are simple strategies you can deploy to choose a compelling topic;

Choose a field of interest

To write a good research paper, explore your options on an area of biology that you are interested. Take time and think about what you are passionate about in your field of study and make that your starting point. Once you have browsed through your topic of interest, you should check on the available materials that will aid your research.

Make a research question

Creating a research question is the most challenging task compared to writing the paper. A good research question should be thought-provoking and with a certain objective. Your research question should attract readers to go through your paper even if they don’t know much about the subject.

Come up with research topic ideas

A good place to start is going through your course material for some inspiration. Alternatively, you may write down a list of interesting facts and concepts that you heard in class and see good topical ideas. Your mentor or instructor can also offer good advice on possible research proposal topics you should work on.

Create a thesis statement

A thesis statement acts as a ground statement for your biology research paper. It clearly defines your topic of research and the points that validate or invalidate your object of study.

What are some biology topics?

Biology is a wide field consisting of various sub-fields. If you are looking for a research paper to write on or a major biology option, here are a few modern and exciting options.

1.CRISPR and genetic engineering

CRISP is a search, pick, and paste function for editing DNA. This organizational sequence naturally occurs in bacteria and archaea.

2.  Epidemiology

Epidemiology is the study of how diseases spread in a population. This branch of biology offers a lot of avenues for exploration with recent epidemics such as Ebola and COVID-19.

3. Cancer biology

Cancer is an umbrella term for many diseases whose main characteristic is abnormal cell growth. With advanced research, the path to finding cures and eradication measures for certain types of cancer is on track.

4. Endangered species recovery

Many organisms, both big and microscopic, that keep the earth’s ecosystem running are going extinct. Working as a wildlife biologist to make conservation efforts more fruitful could be a very fulfilling path.

5. Astrobiology

This is the study of what and how life forms exist beyond earth in the cosmos. It is a relatively new field in biology open for exploration.

6. Synthetic biology

Synthetic biology studies the design of organisms to perform useful tasks. For example, you can study the production of medical-grade insulin through microorganism engineering.

7. Epigenetics

This is the study of the transfer of genes from one generation to the other. The stress our forefathers underwent affects us today through our genes.

History of Biology

Biology is the study of life. Ancient Greeks are the first explorers of the anatomy, physiology of living things and organisms. Enormous contributions were made in ecology, botany, zoology, and taxonomy through Theophrastus, a biological work by Aristotle.

Medicine became more prevalent in the middle ages. It is believed that Islamic scholars were the first to introduce medicinal science. The Neolithic revolution brought attention to ancient practices of animal husbandry and farming.

The modern and Renaissance periods greatly influenced the flourishing of Botany. Plants were considered to have incredible medicinal properties.
