  all the islands.

• Different species of finches lived on

  different islands.

• Various species of finches lived on

Charles Darwin found fossils that looked like ancient versions of living species.

From this evidence Darwin suggested that Earth was

• much more than 6000 years old.

• less than 6000 years old.

• only 6000 years old.

• about 1000 years old.

What is the process in which humans breed organisms for certain traits?

• natural selection

• inheritance of acquired characteristics

• artificial selection

• descent without modification

Individuals that are well adapted to their environment will survive and produce

• fewer mutations

• more offspring

• stronger genes

• better traits
