Evolution Test Remediation

The picture shows the development of a chicken and human. Number 4 on the chicken and human both have tails. What do these similarities tell us about the two organisms?

• They share a common ancestor.

• Humans are birds

• Birds are humans

• They are not related at all.

Which layer contains organisms that became extinct FIRST?

• 6

• 4

• 3

• 1

Natural selection is essentially when organisms with ​ (a)   traits can reproduce and pass on the traits to their ​ (b)   . These offspring can also ​ (c)   . The organisms without the favorable traits could die and become ​ (d)   .

• desirable
• offspring
• reproduce
• extinct
• parents

Salmon Females lay anywhere from 1,000 to 17,000 eggs and bury the eggs in the gravel at the bottom of the stream. What is the advantage to laying so many eggs?

• Having a large number of offspring encourages competition for finite resources.

• Having a large number of offspring increases the chances that some will survive.

• Having a large number of offspring promotes the chance of favorable mutations.

• Having a large number of offspring allows for more gene flow between populations

Speciation, a process in which a new biological species arises, occurs in stages and results in a species with an improved “fit” for its environment. Speciation can result when two populations have become –

• Too Small

• One population

• Reproductively Isolated

• Extinct

How does natural selection produce change?

• Some individuals in a population survive and reproduce to pass on advantageous traits.

• Some individuals in a population survive and become sterile, causing advantageous traits to be concentrated among the individuals that are born with them.

• Some individuals in a population survive and produce the same amount of offspring as others, causing harmful and advantageous traits to be equally dispersed throughout a population.

• Some individuals in a population survive and produce fewer offspring than others, causing harmful traits to be eradicated within a population.

What is an adaption?

• Self-pollination

• Two animals reproducing

• A change based on the environment.

• When two animals are not related

Which of these most likely determines if a mutation will become an adaptation in a species?

• Natural Selection

• Mitosis

• Genetic Variation

• Succession

Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called natural selection. (a)  

• Survival of the Fittest
• Extinction
• Derived trait
• Artificial Selection

What is the term for a feature that allows an organism to survive in its environment?

• adaptation
• variation
• homologous structure
• vestigial structure
