Bio Lesson 7: Evolution & Natural Selection

Why are advantageous traits more likely to be passed on to the offspring?

• Because parents with those traits can teach their offspring
• Because parents with those traits can surive and reproduce better
• Because parents with those traits care more about their offspring

Do organisms "decide" to adapt?

• Yes, if they don't adapt they will die
• No, they can't adapt.  They either have adaptations or they don't
• No, they adapt by random mutations during their lifetime
• Yes, they can force mutations in one lifetime

An adaptation is

• how animals change over time.
• a characteristic that helps an organism survive and reproduce
• a theory of how organisms change.
• the genes in an organism that determine how an organism is going to look.

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce more, therefore passing down their genes to their offspring?

• Evolution

• Variation

• Adaptation

• Natural Selection

The diagram shows fossils in different rock layers. Using relative dating methods, which of these statements about the age of these fossils is most likely correct?

• Fossil A and C are the same age

• Fossil B is older than fossil C

• Fossils A is older than fossil B

• Fossil D is older than fossil C

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, thus light mice have more offspring.

• The hawks eat more light mice than dark mice because they can see the light mice more easily, thus dark mice will have more offspring.

• The hawks eat more dark mice than light mice because they can see the dark mice more easily, thus the light mice have more offspring.
