14.- Natural Selection

By changing the color of trunks

By changing the color of moths

Contaminating the environment

Guided changes in allele frequency

Random changes in allele frequency

Random changes in gene proportion

It was the first study of Darwin

The study showed how finches had evolved

It was an example of how finches had adapted to different environment

Individual variation ,heritable variations, adapted descendants and competition for resources

Individual variation, heritable variations, adapted descendants and reproduction

Individual variation, heritable variations, too many descendants and natural selection

Competition among living things for getting food

Competition for resources needed to live

Competition for reproduction and ensure the survival of the specie

Individual

Population

Both

Because he was very far away from them

Inbreeding resulted in weaker and sickly descendant

Inbreeding resulted in infertility

Because of natural selection against short necks

Because of natural selection for long necks

Because of natural selection against long necks

Natural selection for extreme phenotypes

Natural selection against extreme phenotypes

Natural selection against medium phenotypes

Selection against common traits

Selection for common traits

Selection for extreme traits without any change in the environment
