5 Evolution Factors Quiz

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
