What are the main differences between human and chimpanzee skulls?
Chimp skulls have heavy brow ridges that extend well in front of the cranium. By contrast, the forehead of a human skull rises directly from the brows. Between the eyes, a pronounced nasal bone in the human skull contrasts sharply with the flat curve that leads to the chimpanzee nasal opening.
Which primate has Y 5 molars?
hominoids
Whereas Old World monkeys have bilophodont molars, hominoids have Y-5 molars , which feature five cusps separated by a “Y”-shaped groove pattern (Figure 5.31).
How do teeth of Old World monkeys and apes differ?
How do the teeth of Old World monkeys and apes differ? Apes have a Y-5 pattern of cusps, whereas Old World monkeys have a bilophodont pattern. Old World monkeys have a 2/1/3/3 dental formula, whereas apes have 2/1/2/3. Apes have a tooth comb, but Old World monkeys do not.
What is the difference between human and chimpanzee?
It was found to differ from the human genome with which it was compared, nucleotide-for-nucleotide, by about 1.23 percent. This amounts to about 40 million differences in our DNA, half of which likely resulted from mutations in the human ancestral line and half in the chimp line since the two species diverged.
Which dental trait is present in great apes and humans?
Ape premolars have only one cusp, which is useful for sharpening canines. Also, the front teeth of apes are generally larger than the back teeth, while in humans, the back teeth are generally larger than the front. Canines in apes are pronounced, while in humans they are blunt and reduced.

are characteristic and enable them to move arboreally. The ape dental formula is the same as humans, but there is an emphasis on the front teeth, and the canine teeth can be pronounced in some ape males, primarily for display purposes.

How does the ape foot differ from the human foot?
The ape foot is dexterous, allowing for flexible mobility. Compared to the double-arch of the human foot, the ape foot is flat, though both humans and apes walk plantigrade (heel to toe). The hallux (big toe) on each ape foot is opposable. The opposability
