Essays On Biology

Biology is one of the most exciting areas of science, after all, without biology, we would not exist; our development as creatures is what makes everything else possible.

And it is also an incredibly diverse area of science. When many think of biology, they often think of the subjects they studied at school, things like cells or anatomy. However, biology includes some of the most dynamic fields of science, and there is still more to discover.

Essays about biology might focus on the more straightforward aspects of the subject, for example topics like cells and cell division, or comparative anatomy and the similarities between animals even from very different parts of the animal kingdom.

You might take a wider view of biology. And how living creatures adapt to their habitats and each other. This can be anything from looking at how humans manage to thrive whether they are in arctic wilderness, torrid deserts, or humid rainforests. Or even how animals themselves have adapted as humans have increasingly encroached on their habitats.

Or it could take a longer term, looking at how genetics and heredity work within organisms. And on an even longer term, how these contribute to evolution, and how those small adaptations eventually create new species.

The latest science also provides plenty of topics, biotechnology, and genetic engineering gives modern humans the potential to do things that might have taken millennia before. It means that we might be on the threshold of seeing previously devastating illnesses eradicated. But it might also mean rogue states can threaten us with a targeted virus or antibiotic resistant bacteria.

And, of course, you could explore the ethics of biology. Just because we can selectively alter our genes, should we? Do we risk creating inequality because of access to technology? And how do we handle emotive issues, like genetically altering animals to provide medicines or even organs for human use?

Because biology is the study of life, the range of essay topics is as diverse as life itself. But whatever topic you choose, it’s important to keep a scientific mind, and even on subjective issues, remember to back up your arguments with strong evidence.

When writing an essay on Biology, try looking through the samples on this page. They will help you see different people’s points of view and create your own masterpiece!
