EVOLUTION + SPECIATION - AQA A LEVEL BIOLOGY + EXAM QUESTIONS RUN THROUGH

In this video, I explain ALL of the content required for the "Evolution + Speciation" section for AQA A Level Biology. This includes: causes of variation, effect of selection on allele frequencies, types of selection, allopatric speciation, sympatric speciation and genetic drift. Time stamps are in the comments! I also go through a few exam questions and explain their mark schemes. The content in this video crosses over with other exam boards too. Please leave a comment if you have any questions, I'll be more than happy to answer them!!! :)
