Biogeographical Evidence

DNA evidence is also known as -

Molecular Evidence

Front

Structures that are no longer used by organisms, such as whales' pelvic bones, are known as what type of structural evidence?

Back

Vestigial

Front

Structures that are similar in different organisms are called -

Back

Homologous

Front

Vestigial structures provide evidence of evolutionary history. For example, ostriches may not fly, but they do have wings indicating that they -

Back

have an ancestor that used to fly

Front

According to molecular evidence, which organism is least related to the other two? Options: Lemur, Gorilla, Human

Back

Lemur

Answer explanation

Lemurs have the most differences between the gorilla and the human. This means that the human and gorilla are more closely related in evolution that the lemur is with either.

A rapid change in evolution followed periods of being unchanged is known as -
