B6.1: How was the theory of evolution developed?

#B6.1.1

state that there is usually extensive genetic variation within a population of a species

#B6.1.2

recall that genetic variants arise from mutations, and that most have no effect on the phenotype, some influence phenotype and a very few determine phenotype

#B6.1.3

explain how evolution occurs through natural selection of variants that give rise to phenotypes better suited to their environment

#B6.1.4

explain the importance of competition in a community, with regard to natural selection

#B6.1.5

describe evolution as a change in the inherited characteristics of a population over a number of generations through a process of natural selection which may result in the formation of new species

#B6.1.6

explain the impact of the selective breeding of food plants and domesticated animals

#B6.1.7

describe how fossils provide evidence for evolution

#B6.1.8

describe the work of Darwin and Wallace in the development of the theory of evolution by natural selection

#B6.1.9

describe modern examples of evidence for evolution including antibiotic resistance in bacteria

#B6.1.10

explain the impact of these ideas on modern biology and society

B5.6
What can happen when organs and control systems stop working?
B6.2
How do sexual and asexual reproduction affect evolution?
