A Level Biology Revision "Evidence for Evolution"

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/...

In this video, we look at the evidence for evolution by natural selection. First we explore Darwin's theory of evolution and how he developed this. We also look at Alfred Russel Wallace. We then look at how Darwin's theory of evolution is supported by evidence from fossils, comparative anatomy (including the pentadactyl limb) and comparative biochemistry.
