Answer 1

Basic Idea of Natural Selection

Individuals with specific inherited traits will survive and reproduce with individuals with other traits

Evolutionary Adaptation

inherited characteristics that enhance organisms' survival and reproduction in a specific environment become more common

5 types of Evolution

- edward from Fossils

- evidence from homologies

- evidence from evolutionary trees

- evidence from natural selection

- evidence from population

The Finches lived in areas with a lot of hard shelled nuts had strong thicker beaks, compared to those who lived in areas with insects and fruit had more delicate beaks

all organisms struggle to survive

- some are better adapted to the environment than others

one example of natural selection

pesticide residence in insects

population

a group of individuals of the same species that live in the same area and interbreed

genetic variation

- sexual reproduction

- mutations

gene pool

all copies of every type of allele at every locus in members of the population

what is genetic drift

a change in the gene pool of population due to chance
