Extinction (Hybridisation of Wildcats) Biology GENETICS AND EVOLUTION Objectives Outline the process of extinction Give examples of endangered and extinct species Explain different causes of extinction Analyse the traits of different cats to estimate their genetic composition Consider the limitations of this phenotypic data Organisms are adapted to survive and compete in their environment. If the environment changes they can struggle to survive and reproduce If this happens to a whole species it can go extinct Causes of Extinction: catastrophic events, habitat change, over exploitation, alien invasion, disease, hybridisation Use a series of questions to evaluate photos of cats and identify wildcats. Complete the table for each of the four cats using the trait descriptors. Total the scores and decide which cats are wildcats, hybrids or domestic cats. Links to BBC Winterwatch 2016.
