Derived characters are traits that characterize the last common ancestor that a particular collection of species share. evolved after the last common ancestor that a particular collection of species share. are less suited to the environment than ancestral characters. are more complicated than ancestral characters.

Derived characters are traits that characterize the last common ancestor that a particular collection of species share. evolved after the last common ancestor that a particular collection of species share. are less suited to the environment than ancestral characters. are more complicated than ancestral characters.

A grade is a grouping of organisms that reflect a branch of the evolutionary tree, Prosimii and Anthropoidea are an alternative grade-based classification Genetic evidence suggests that Tarsiers are more closely related to Lemurs and Lorises than they are to haplorhines None of the above
All of the following pieces of evidence can be used to determine relatedness among organisms EXCEPT: - examination of the fossil record for evidence of common ancestry; - similar amino acid sequences in proteins; - similarities in life cycle and development; - morphological similarities due to convergence; - similar DNA sequences.
by studying the limbs and fossils of different animals, such as a horse leg and a human leg, scientists have noticed that there are similarities in their bone structures. this is evidence that their bone structures and limbs may have evolved in similar ways. The scenario is describing a relationship known as causation . The scenario is describing intermediate fossils . The scenario is describing a relationship known as correlation . The scenario is describing transitional fossils .
