Evolution Review KHS

Which of the following best describes the fossils from OLDEST to YOUNGEST?

• Early horses, Dinosaurs, Armored fish, Trilobites

• Trilobites, Early horses, Dinosaurs, Armored fish,

• Trilobites, Armored Fish, Dinosaurs, Early Horses

• Early horses, Armored fish, Trilobites, Dinosaurs

What environment did the organisms in the two oldest layers, likely live in?

• Land

• Ocean

• Jungle

• Frozen Tundra

During his visit to the Galapagos islands, Charles Darwin discovered several distinct species of finches.  These groups had been geographically isolated from one another.  Many of them lived on different islands. The species of finches differed mainly in feeding behavior, beak structure, and body size. Yet, all of the species shared some characteristics. 

Which of the following statements best explains the differences between the finches?

• The beaks of the finches changed so the finches could better access different sources of food.

• The beaks of the finches changed so all of the finches could eat the same type of food.

• The beaks of the finches changed as the species of finches migrated to the same island.

• The beaks of the finches changed as the finches’ body sizes changed.

The bones that make up the forelimbs of humans, bats, porpoises, and horses are similar. Which of the following statements best supports the evolutionary relationship of these animals?

Select two.

• Divergent Evolution

• Converegent Evolution

• The animals use their forelimbs for identical activities but live in different environments.

• The animals share a common ancestry but have adapted to different environments.

This diagram shows what type of structures? What is term that best describes the process?

• Vestigial structures, Converegent evolution

• Homologous structures, Divergent Evolution

• Analogous structures, Convergent Evolution

• Analogous structures, Punctuated Evolution

Embryology is the branch of biology and medicine concerned with the study of embryos and their development. What does this indicate about these vertebrates? Choose two.

• These animals were not descended from a common ancestor.

• These animals all developed from convergent evolution.

• These animals share a common ancestor.

• These animals developed from divergent evolution.

Female peacocks pick their mate according to the male's tail. The ones with the largest and brightest tails mate more often. Today, because most breeding males have large, bright tales, it is rare to find males that do not have bright feathers.

This is an example of:

• Overpopulation

• Variation

• Selection

• Adaptation

Tawny owls (Strix aluco) come in two basic shades: brown and less brown. Though regular brown is the dominant trait, the pale brown or grayish color helps some owls blend in with snowy trees and hide from predators. More snow typically equals more gray owls.

With milder/warmer winters in Finland, one population of tawny owls showed a significant uptick in brown-plumed owls over the last 28 years.

It makes sense that natural selection might favor brown coloration because:

• With more snow, brown owls are better at blending in with the surrounding forest, giving those birds a better chance to survive and reproduce.

• With less snow, white owls are better at blending in with the surrounding forest, giving those birds a better chance to survive and reproduce.

• With less snow, brown owls are better at blending in with the surrounding forest, giving those birds a better chance to survive and reproduce.

• With more snow, white owls are better at blending in with the surrounding forest, giving those birds a better chance to survive and reproduce.

Which of the following correctly identifies the type of evolution in each graph?

• Graph A: Gradualism / Graph B: Convergent

• Graph A: Punctuated / Graph B: Gradualism

• Graph A: Divergent / Graph B: Punctuated

• Graph A: Gradualism / Graph B: Punctuated

Which of the following conclusions is best supported by the data given in this chart? Select 2

• Modern bears evolved from species that are now extinct.

• The short-faced bear was the ancestor of the Asiatic black bear.

• The Asiatic Black Bear, the American Black bear the Brown Bear are the most closely related to each other than they are to the Spectacled bear..

• Natural selection favored the brown bear over the American black bear
