Evolution

Butterfly and bird wings are structually different, but are both used for flying. This evidence shows that...

• the species are closely related

• the species share a common ancestor

• The environment favors flying

Modern day whales have bones that look like hind limbs (legs), but serve no purpose. This is an example of

• homologous structures

• analogous structures

• vestigial structures

 

A catepillar turning into a butterfly is an example of

• Evolution

During the evolution stations, you found that humans and rabbit embryos look very similar. What does this evidence most strongly suggest?

• The similarities are a coincidence

• They share a common ancestor

• Rabbits and humans live in the same environment

• Rabbit and human embryos were mislabeled

 

A giant storm kills off many coyotes that cannot swim. However, some coyotes that can swim survive. This is an example of

• directional selection

• disruptive selection

• stabilizing selection

 

Butterfly and bird wings are structually different, but are both used for flying. This is an example of

• colorblind or not

• various colors

• varied meat doneness
