Evolution Basics

Evolution is best defined as:

• the process which organisms die.

• the process which organisms change over time.

• the process which organisms that are extinct become revived.

• the process which non-living things fossilize.

• Vestigial Structures

• DNA

Adaptations are:

• physical or behavioral tendencies.

• physical or behavioral traits/characteristics that help an organism survive and reproduce.

• physical or behavioral traits/characteristics that do NOT help the organism

• genetic mutations that have gone wrong.

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

A species is defined as:

• a group of organisms that are extremely different.

• a group of organisms that have similar characteristics and always live in the same place.

• a group of organisms with similar characteristics and can reproduce to make fertile offspring.

• any two organisms to make a hybrid.

What statement is true regarding why natural selection can be easily seen in insects and bacteria?

• Natural selection only occurs in prokaryotic cells

• Insects and bacteria can reproduce faster than more complex organisms and pass on selected traits quicker

• Insects were the first multi-cellular organism to live on land

• Bacteria have directly evolved from insect traits.
