Main similary between Darwinian beliefs and the ideas of Lamarck
gradual evolution by passing down of genetics
5 factors of evolution
Genetic drift, sexual selection, mutation, gene flow, natural selection
Occurs when genetic frequencies in a population change randomly because of random deaths - impactful in small populations
Genetic Drift
Main difference between Darwiniam beliefs and ideas of Lamark
Lamark said evolution happens within lifetime
What he might also use to refer to genetic drift
Small population
New genes are introduced to the population randomly during reproduction in the change of gene structure
Mutation
Preference by one sex for certain characteristics in individuals of the other sex
Sexual selection
What he might also call sexual selection
Nonrandom mating
The transfer of genetic variation from one population to another
Gene flow
Adapts for better traits in a particular environment, advantageous genes become more present in the gene pool
Natural selection
Which factors increase variety in the gene pool
Mutation, gene flow
Which factors decrease variety in the gene pool
Genetic drift, sexual selection, natural selection
