although Lamarck hypothesized that adaptations to the environment did occur, he also believed that

• mass extinctions did not occur

• offspring inherited characteristics acquired by their parents during the lifetime

• similar organism do not share the same common ancestor

• natural selection is the source of all diversity

according to Lamarck's ideas if a parent lost an arm then that persons children would

• inherit one arm

• inherit three arms

• inherit one arm stronger then the others

• inherit two arms weaker then the other

the Patagonia hare and the European rabbi are both small mammals which are distantly related but are very similar in their overall appearance, Darwin's explanation for this is that

• the similarity of the two unrelated species is simply coincidence

• each have adapted to very similar ways to similar environment

• the two species were created to have similarities

• the two species must be related

This image shows that 

• These animals have no simliarities in their structures. 
• two different species may have evolved from a common ancestor. 
• These animals are from the same species. 
• These animals likely evolved from different ancestors due to their differences.

the presence of a vestigial organ supports evidence of evolution because

• both the vestigial organ and the functional organ perform the same function

• the vestigial organ is similar to a functional organ in a related species, having been passed down through ancestors

• the vestigial is unique

• the vestigial represents variation in a species
