Which species’ DNA is most similar to the DNA of the toothed whale?

Hippopotamus

Baleen Whale

Grazing Mammals

Camels

The similarities of organisms in which two areas numbered in the picture provide the best evidence for common ancestry?

1 and 2

3 and 4

5 and 6

7 and 8

Some organisms that share a common ancestor have features that have different functions, but similar structures. These are known as

vestigial structures

analogous structures

anatomical structures

embryology

What conclusions can be made based on this table shown?

the American black bear and the giant panda are most closely related

the giant panda and the red panda are most closely related

the red panda and the racoon are the most closely related

the giant panda and the racoon are most closely related

The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that -

they live in the same type of environment.

have slowly evolved to become herbivores.

have a common ancestor.

Which layer is the youngest

10.

Which layer is the oldest

11.

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

are descended from a common ancestor

Have very similar skeletal structures

belong to the same species

must range great distances to eat

12.

The similarities of the bones in the diagram provide evidence that---

The organisms shown lived in the same natural envionrment

The organisms shown may have developed from a common ancestor

The organisms shown have the same genetic diseases

All vertebrate species have identical forelimbs

13.

In stage one (top row) of these embryos, most of the embryos________

look very similar.

have very different features.

show different stages of development.

have only a tail if they are non-human.

14.

Which scientist visited the Galapagos Islands and came up with the theory of natural selection?

Theodor Schwann

Gregor Mendel

Charles Darwin

Rudolf Virchow

15.

In recent years "SuperBugs" (bacteria that aren't effected by antibiotics) are becoming more and more common. How could natural selection explain this?

Superbugs survive antibiotics and reproduce

Antibiotics cause bacteria to become superbugs

We have always had the same amount of superbugs; modern media just discusses them more.

There is no reliable data on the origin of super bugs.

16.

Why do peppered moths tend to be the same color as the trees on which they live?

The coloring goes along with tasting like the tree.

It keeps the moth the same temperature as the tree.

It makes the moths faster than the birds

It makes the moths harder to see.

17.

Why are advantageous traits more likely to be passed onto offspring?

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

18.

Which organisms are most likely to survive?

the best adapted

the fastest

the strongest

the most domesticated (tamed)

19.

Yellow toucan birds seek out one another to make babies together and tend to avoid the green toucan birds.

Genetic Drift

Non-random mating

Gene flow

Mutation

20.

Mutations are important because they bring about

death of the organism in which they develop

genetic variation needed for a population to evolve

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population
