In the Great Lakes region of North America, gray wolves and coyotes are similar species but do not mate because their breeding periods occur at different times of the year.

Geographic isolation

Behavioral isolation

Temporal isolation

The American toad (Anaxyrus americanus) and Fowler's toad (Bufo fowleri) live in the same area. However, The American toad mates in early summer while Fowler’s mates in late summer.

Geographic isolation

Behavioral isolation

Temporal isolation

A type of isolation in which two populations become separated by a physical barrier such as a canyon, river, lake, preventing the two populations from interbreeding.

Geographic isolation

Behavioral isolation

Temporal isolation

A population of chimpanzees was separated when the forest that they lived in had a section cut down and a town was built. After a long period of time, the chimpanzees came back into contact but were incapable of breeding. Which of the following best describes the process that occurred?

adaptation

speciation

convergent selection

stabilizing selection

Which is an example of temporal isolation?

flowers that bloom in different months

birds that have different mating calls

fruit flies that mate in different locations

squirrels that have different fur colors

Genetic drift is change in the allele frequency of a population due to...

random chance

natural selection

non-random mating (sexual selection)

artificial selection

A virus killed most of the seals in the North Sea (e.g. dropped the population from 8000 to 800). In an effort to help preserve the species, scientists caught 20 of the remaining seals and used them to start a new population in the northwest Pacific Ocean. Which of the following statements would accurately describe the new population?

The new seal population is genetically less diverse than the original population

The new seal population is genetically more diverse than the original population

There is equal genetic variety compared to the original population

None of the answers

Which of the following is an example of the bottle neck effect?

Bald Eagles are hunted until near extinction, population recovers.

Small group of iguanas floats to an island, starts a new population.

Red fox pups are more likely to survive in a snowy environment if they are born white.

Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.

Which of the following is an example of the founder effect?

Bald Eagles are hunted until near extinction, population recovers.

Small group of iguanas floats to an island, starts a new population.

Red fox pups are more likely to survive in a snowy environment if they are born white.

Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.

10.

If two organisms have similar traits of DNA they are probably

share a common ancestor

share a common environment

share a common population

speciation

11.

If species A and B have very similar genes and proteins, what is probably TRUE?

species A and B share a relatively recent common ancestor

species A evolved independently of species B for a long period

species A is younger than species B

species A is older than species B

12.

Which of following in NOT a critial part of the theory of evolution?

overproduction

consistent environment

genetic variation

struggle to survive

13.

Which of the following provides molecular evidence in support of the idea of evolution?

Developing pig embryo looking like a developing human embryo

Human proteins having amino acids like monkey proteins

Fossil skull of a 12 Million-yr-old mammal resembles horse

Bones in a human arm are similar to bones in a frog's leg

14.

Which of the following is true of genetic bottlenecks?

They reduce the fertility of the surviviors

Occurs when there are major natural disasters that kill the majority of the population

Result in increased genetic diversity

Due to mutation rather than natural selection

15.

Scientists believe that the species Homo sapiens originated in Africa and migrated out of Africa to compete with existing hominid species in other territories. Which field of study would provide us with evidence that Homo sapiens came to what is now the Americas using a land bridge between Russia and Alaska that became covered with water when the Ice Age thawed?

Biogeography

Comparative Anatomy

Embryology

Molecular Biology

16.

artificial selection

reproductive isolation

genetic drift

mutations

18.

The animals in the picture do not live in the same population. They are found in different parts of the world, but are all still part of the camel family. What can be said about these animals?

They belong to the same species

It is difficult for them to find food to eat

They have a very similar skeletal structure

They descended from a common ancestor

19.

What is a genetic characteristic of favorable adaptations?

These adaptations cannot be passed on to the next generation.

These adaptations are acquired by increased use of an organ.

These adaptations reduce the organism's chances of survival.

These adaptations improve the organism's chance of survival.

20.

Hybridization

reproductive isolation

artificial selection
