Work in a small group or alone to complete this exercise. Theropithecus lived in Africa at the end of the Pliocene and the early Pleistocene. It had two premolars in each mouth quadrant and bilophodont molars. Its teeth indicate an unusual diet that emphasized grasses. It had larger canines and a much larger body size than its living primate relatives. Its postcranial traits suggest it was a well-adapted terrestrial quadruped.
1. Based on this information, do you think this fossil has more in common with living colobines or cercopithecines?
2. Describe one trait you used to make this identification.

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?

Dermal tissue in plants stores 1.extra food 2.transports water and nutrients 3.transports waste materials 4.is similar to epithelial cells in animals
