1. History of life
|
1.1 Life has been on Earth for a long time
|
|
1.2 Present day life forms are related to past life forms
|
|
1.3 Large scale environmental changes (caused by geological, geophysical, astronomical factors) and biological evolution are linked
|
|
1.4 Anthropogenic environmental changes and biological evolution are linked
|
|
1.5 Many life forms that once existed have gone extinct
|
|
1.6 Rates of evolution vary
|
|
1.7 Life forms/species/ change through time
|
|
2. Evidence for Evolution
|
2.1 Similarities and/or differences among existing organisms (including morphological, developmental, and molecular similarities) provide evidence for evolution
|
|
2.2 Evolution can be directly observed
|
|
2.3 The fossil record provides evidence for evolution
|
|
2.4 The geographic distribution of extant species provides evidence for evolution
|
|
2.5 Artificial selection provides evidence for evolution
|
|
2.6 Organisms’ features, when analysed in relation to their environment provide evidence for evolution
|
|
3. Mechanisms of Evolution
|
3.1 Evolution is often defined as a change in allele frequencies within a population
|
|
3.2 There is variation within a population
|
|
3.3 Living things have offspring that inherit many traits from their parents but are not exactly identical to their parents
|
|
3.4. Evolution occurs through multiple mechanisms
|
|
3.5. Natural selection acts on the variation that exists in a population
|
|
3.6 Inherited characteristics affect the likelihood of an organism’s survival and reproduction
|
|
3.7 Sexual selection occurs when selection acts on characteristics that affect the ability of individuals to obtain mates
|
|
3.8 Genetic drift acts on the variation that exists in a population
|
|
3.9 Fitness is reproductive success—the number of viable offspring produced by an individual in comparison to other individuals in a population/species
|
|
3.10 Species can be defined in many ways
|
|
3.11 Speciation is the splitting of one ancestral lineage into two or more descendant lineages
|
|
3.12 Evolution does not consist of progress in any particular direction
|
|
4. Studying evolution
|
4.1 Scientists study multiple lines of evidence about evolution
|
|
4.2 In everyday life we can find applications of evolutionary biology
|
|
4.3 Classification is based on evolutionary relationships
|
|
5. Nature of Science
|
5.1 Science is a human endeavor (achievement)
|
|
5.2 Science provides explanations for the natural world
|
|
5.3 Science is based on empirical evidence
|
|
5.4 Scientific ideas can change through time
|
|
5.5 Scientific theories are built through a transparent collective endeavor
