Evolution is responsible for both the remarkable similarities we see across all life and the amazing diversity of that life — but exactly how does it work? Here, we’ll find out.

Population genetics and evolution takes place on a huge scale, as you know. What this means is that each environmental pressure can be thought of as a variable that lasts hundreds of thousands of years. If the pressure is short and not really that impactful, the evolution will be minimal or non existant.
