When systematists study morphological or behavioral traits to reconstruct the evolutionary history of a group of animals, they assume that: a. similarities and differences in phenotypic characters reflectunderlying genetic similarities and differences. b. the animals use exactly the same traits to identify appropriatemates. c. differences in these traits caused speciation in the past. d. the adaptive value of these traits can be explained. e. variations in these traits are produced by environmentaleffects during development.
In 1798, a stuffed platypus specimen was delivered to the British Museum. Reports that it laid eggs created much confusion. To modem biologists, a platypus is clearly a mammal. It has fur and the females produce milk. Young animals have typical mammalian teeth that are replaced by hardened pads of the bill as the animal matures. Why do you think modem biologists can more easily accept that a mammal can have some reptilelike traits than scientists who were considering this animal in the late 1700s?
Which of the following could be an example of microevolution? a. a slight change in a bird populations color due to a smallgenetic change in the population b. large differences between fossils found near the groundsurface and those found in deep rock layers c. the sudden disappearance of an entire genus d. the direct evolutionary link between living primates andhumans e. a flood that drowns all members of a population

The great variety of species alive today resulted from the diversification of ancestral species. c. Natural selection drives some evolutionary change. d. Natural selection preserves advantageous traits. e. Natural selection eliminates adaptive traits.
Exaptations are traits that: a. prepare some organisms for future environmental changes. b. appear in lineages as a result of an adaptive radiation. c. evolve in anticipation of a species future needs. d. are useful in new situations before natural selection alters them for a new function. e. occur in animals, but not in plants.
