• examples of fossils.

• acquired traits.

• examples of natural variation.

Biogeography is the study of:

• how extinct species can be related to living species.

• where species and their ancestors live.

• how different species can interbreed.

• how animals migrate over time.

How did Charles Darwin view the fossil record?

• As evidence that Earth was very young.

• As evidence of similarities of species long extinct.

• As evidence that traits are acquired through use or disuse.

• As interesting but unrelated to the evolution of modern species.

Why do DNA and RNA provide evidence of evolution?

• Because no two organisms have exactly the same DNA.

• Because each RNA codon specifies just one amino acid.

• Because all organisms use the same molecules (amino acids, codons & nucleotides).

• Because there are lots of similarities among the genes of most species.

Darwin’s concept of natural selection was NOT influenced by __________.

• the geologic work of Charles Lyell.

• his trip on the H.M.S. Beagle.

• the work of Gregor Mendel with genetics

• the work of Malthus on populations

How does comparing the skeletons of these animals provide support for the theory of evolution?

• It provides information about the organisms' habitats.

• It shows possible common ancestry between organisms.

• It provides information to determine the organisms' ages.

• It shows chromosomal similarities between organisms.

The similarities of the darker brown bones provide evidence that

• the organisms may have evolved from a common ancestor

• all species have one kind of bone structure

• the cells of the bones contain the same type of mutations

• the animals' limbs have adapted to different niches (ways of movement)
