________ anatomy is the study of the similarities and differences in the structures of different species

• Human

• Comparative

• Relative

Nature has a way of causing organisms that inherit advantageous traits to survive and reproduce more successfully than the ones that don't. This process is known as...

• natural selection
• genetic variation
• adaptation
• overproduction

A beetle's ability to camouflage (blend in) with a nearby leaf allows it to escape a hungry frog's appetite.
This is an example of an:

• overproduction
• genetic variation
• selection
• adaptation

Scientists have found evidence that about 2.4 million years ago a gene regulating jaw muscles mutated and may have led to the more graceful human jaw we see today. The diagram below shows the skulls of 3 hominid species. Which statement below most closely explains the link between jaw size and hominid evolution?

• The jaws of hominids evolved to be smaller and less protruding over time as did the skull.

• The jaws of hominids evolved to be larger and more protruding over time.

• There appears to be no change in the jaws of hominids over time.

• The jaws of hominids changed over time due to a change in brain size
