Selection
What this topic asks you to be able to do
- Describe natural selection by referring to: the variation within populations; the large number of offspring produced; the struggle for survival, including the competition for resources; individuals better adapted to their environment than others going on to reproduce; and these individuals passing their alleles on to the next generation
- Describe how natural selection can cause a population's inherited features to evolve over time
- Outline the emergence of antibiotic-resistant bacterial strains, including MRSA, as a case of natural selection
- Describe artificial selection (selective breeding) by referring to: humans choosing plants or animals that have desirable features; crossing the chosen individuals to give the next generation; picking out the offspring that show the desirable features; and repeating this over many generations
- Outline the part played by artificial selection in creating plants and animals of economic value
