 The snowshoe rabbit has white fur in winter and dark fur in summer. What is the main survival advantage of this fur color change to the rabbit?

• The light fur keeps the rabbit from getting sunburned in summer.

• The dark fur absorbs more sunlight so the rabbit is warmer in winter
• The white fur is more valuable to fur trappers, so the animals will be trapped and better fed in the winter.

• vestigial
• analagous
• homologous
• evolutionary

 Which term is used to descibe body structures that look alike and serve a similar function but are not descended from a common ancestor?

• vestigial structures
• evolutionary features
• homologous structures

• some organisms were heavier and stronger
• some organisms were more likely to reproduce
• not all organisms had the same natural life span
• not all organisms were equally suited to gathering food

Which term describes body structures in different organisms that have different outward appearances but develop from the same embryonic tissues?

• homologous
• divergent
• convergent
• vestigial

An inherited trait that has become common in a population is an example of

• natural selection

• gradualism

• adaptation

• population

Natural selection causes the frequency of favorable alleles to
