SCB-M4 U4.3 Adaptation and Evolution

Multiple Choice

Darwin theorized that individuals having an advantage due to their traits or abilities will be more likely to survive and reproduce.  This theory is known as

• evolution

• speciation

• adaptation

• natural selection

Multiple Choice

The differences among a species, like different bird beaks, are called

• genes.

• variations.

• traits.

• theories.

Multiple Choice

The struggle for existence against other members of an organisms species is

• Competition

• Natural Selection

• gene flow

• genetic drift

Multiple Choice

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

Multiple Choice

What factor must be in place for natural selection to occur?

• struggle for existence (overproduction)

• genetically identical individuals

• random mating

• no immigration or emigration 

Multiple Choice

Genetic differences between organisms of the same species

• Variation

• Adaptation

• Behavior

What is an adaptation?

• A trait that increases the fitness of an organism.

• A trait that an organism acquires without genetic influence.
