Beyond the human eye exists an entire world, one that forms the foundation of life as we know it. In this installment of our Introduction to Biology series, we’ll take a closer look through the microscope at genes and DNA.
What is a species? To this day, scientists disagree. The idea of what a species truly is incites quite a bit of extensive, often circular discourse, so here’s a quick look at one of the major schools of though on the definition of a “species.”
It’s difficult to tell species apart. This can be especially challenging when you have little to distinguish them but physical features. The biological species concept attempts to solve this problem by setting a clear definition of species based on reproductive capabilities. Here’s a brief overview of this school of thought.
Biology is the foundation of the life sciences. Without a basic understanding of this branch of science, you will be hard-pressed to thoroughly understand other topics. This biology series will introduce you to basic concepts of biological sciences and reproduction.
