What most likely caused the finches on the Galapagos Islands to have beaks that were differnt from the finches living on the South American mainland?

• They were different types of food available on the island.

• The finches on the islands had to drink salt water.

• There were different types of predators living on the island.

What is it called when an organism is best adapted to its environment, it will survive and reproduce more successfully than other organisms less adapted?

• cloning

• evolution of all species

• natural selection

• selective breeding

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the trait is an acquired phenotype.

Natural selection is when ____________ decides who survives and who doesn't

• nature

• humans

• animals

• years
