  1. Selective Breeding GioRaagas, Alyssa San Jose, Nora Hartel, Astrid Crowley

  2. What is it? • Selective breeding – When animals and plants are bred for specific traits • Selective breeding has produced many types of animals and foods that nature could not have done alone • Ex. Dogs are subject to selective breeding for their coats, size, color etc. • When given a variety of an animal, we choose the types of variations with specific traits, and continue to interbreed them and create a new variation

  3. Validity of selective breeding If selective breeding is successful and more common, it is a stronger piece of evidence for evolution

  4. Artificial Selection Selective breeding is also called ‘artificial selection’ the same genetic process as ‘natural selection’. The only difference is that in artificial selection it is not nature but humans influencing the evolution of a particular species.

  5. Natural Selection Selective breeding provides evidence for natural selection because it shows that ‘selection’ can indeed lead to “cumulative change in the heritable characteristics of a population”. E.g. when people select their mates to their preferance, e.g. taller people = taller children
