A Level Biology Revision "Adaptations"

????

In this video, we look at the adaptations of living organisms. First we explore what is meant by anatomical, behavioural and physiological adaptations, giving examples of each. We then explore what is meant by convergent evolution and look at how this is seen in placental moles and marsupial moles.
