BSHS Evidence of Evolution and Primate Evolution

1. The scientific theory of evolution is supported by different types of evidence. These diagrams show the skeletons of two different animal species.

How does comparing the skeletons of these animals provide support for the scientific theory of evolution?

• It provides information about the organisms' habitats.

• It shows possible common ancestry between

  organisms.

• It provides information to determine the organisms'

  ages.

• It shows possible chromosomal similarities

  between organisms.

According to fossil records, the horses that lived 50 million years ago were much smaller, weaker and slower than modern horses. Which process is most likely responsible for the changes that have led to the increased size, strength, and speed in horses?

• artificial selection

• inbreeding

• migration

• evolution by natural selection

The diagram illustrates an embryonic stage of two organisms.

Which of the following can be determined by observing the embryos shown in the diagram?

• The organisms share a common ancestry.

• The organisms belong to the same genus.

• The organisms are native to the same geographic areas.

• The organisms will grow into anatomically similar adults.

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 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.

• 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.

• Species 2 is most closely related to Species 3

• Species 3 is most closely related to Species 7

• Species 5 is most closely related to Species 6
