How has evolution shaped our species?
« on: 14/05/2012 18:12:07 »
Back in 1973, Theodosius Dobzhansky published an essay titled “Nothing in biology makes sense except in the light of evolution” so to start off we thought we’d find out how the gradual shuffling and shifting of genes over time shapes not only whole populations of living organisms over hundreds and thousands of years, but also acts on rogue cells within the body on a much smaller timescale.

As we usually understand it, evolution refers to a process of change over time, driven by natural selection - so random genetic changes in a population are selected for or against by pressures in the environment.

To get an overview of the processes driving genetic evolution and how has shaped species over time - including making humans what we are today - I spoke to Mark Thomas, Professor of Evolutionary Genetics at University College London. We started by going right back to basics, by thinking about what evolution actually means.
