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:
Universal scientific methods
A universal type of research paper has the following characteristics:
Modeling – a technique when a certain viewpoint of an objective is presented, the scientists gather evidence to back up their standpoint.
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.
Individual scientific methods
An individual type research paper is written through:
Observing a natural phenomenon
Making a hypothesis
For a true hypothesis, find more evidence to back it up
For a false hypothesis, change your angle of research or create a new hypothesis
Conclude your findings
Structure of a biology research paper
A good research paper aligns the writer’s 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 a 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 discoveries, 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 in an area of biology you are interested in. 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 a 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 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, and 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.
During the 19th century, new disciplines such as cytology, embryology, and bacteriology began to emerge. Learning about the history of biology brings you closer to understanding the evolution of science. Here are a few biology research topics that explore the history of the field.
