Biology Unit 7 - Variation and evolution
Following on from Unit 6 Students will find out about how gene mutations occur and how on rare occasions can affect the functioning of the animal or plant. They will link this idea of variation generated by mutations and sexual reproduction to the work of Charles Darwin as they student natural selection and how species evolve.
An understanding of these processes has allowed scientists to intervene through selective breeding to produce livestock with favoured characteristics and in more recent times how it has become possible to clone individuals. Students will look at how scientists have discovered how to take genes from one species and introduce them in to the genome of another by a process called genetic engineering. Students will consider the huge potential benefits that this technology can offer, and why genetic modification still remains highly controversial.
