A new fossil called Darwinius was discovered in Germany. It lived around 47 mya. It had a small brain, short snout, and postorbital bar. Its diet probably included a lot of fruit and leaves. It did not have a dental comb. It had nails instead of claws and was probably an arboreal quadruped. Researchers disagree about whether the fossil is more similar to living haplorhines (the group that includes tarsiers, Old and New World monkeys, apes, hominins) or more similar to strepsirrhines (lemurs, lorises) Required:
a. Describe two features that the fossil shares in common with living haplorhines.
b. Describe two features that the fossil shares in common with living strepsirrhines.

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
