All vertebrate embryos resemble each other during the early stages of development. For example, fish, turtles, chickens, mice, and humans develop tails and gill slits during early stages of development. This suggests that _________.
A.
early embryonic development is conservative

B.
ancestral vertebrates possessed genes that directed the development of tails and gill slits, and all of their descendants still retain those genes

C.
genes that modify the developmental pathways in vertebrates arose later in evolution
Which of the following is an incorrect statement about mutation?
Mutations that are favored by selection are more likely to occur.
Which of the following is a basic requirement for natural selection to be an effective evolutionary force?
A population exhibits some genetic variability.
Provide an example of how biogeography supports the theory of evolution.
Different species inhabiting similar habitats display common traits.
In what way does the human population influence evolution?
A.
Human development changes the habitats of many species, influencing natural selection on those species.

B.
Use of antibiotics by humans has selected for antibiotic-resistant bacterial populations.

C.
Humans are responsible for the many breeds of dogs found today.
The ability of organisms to pass on to their offspring physical changes that the parents developed during their own lifetimes _______.
does not occur
Which of the following lines of evidence support(s) the idea that evolution occurs?
A.

the fossil record
B.
genetic and biochemical analyses

C.
comparative anatomy and embryology


D.
artificial selection
The ostrich is a large, flightless bird. Its wings, therefore, represent _______.
vestigial structures
Which of the following would describe artificial selection?
breeding organisms for the purpose of generating certain features or traits (e.g., dog breeds)
Which of the following are the main points of Darwin’s theory of evolution?
A.
Life on Earth is quite old.

B.
Evolution is gradual and continuous.

C.
Contemporary species share a common descent.

D.
Species are formed and adapt by the process of natural selection.
Natural selection acts on _____.
