What do we call a change in a species over time?
Adaptation
Evolution
Extinction
Environmental influences
An organisms with the “best” traits (adaptations) will live longer and
reproduce more than others, causing changes in the population over time by acting on traits that are heritable
Evolution
Natural Selection
Fitness
Variation
A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. This process is called
Natural Selection
Selective Breeding
Random mutations
Variations in a species
Based on the number of differences in amino acid sequence, which pair of organisms is least related to each other?
Fruit fly-wheat
Human - wheat
Fruit fly- pigeon
Human-horse
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
The ability to walk upright on two legs is called:

quadropedalism
bicyclepedalism
tripedalism
