6.  

How do the skulls of adult chimpanzees and humans differ? (Activity 24B)

Adult chimpanzees have a less angled skull.
Adult chimpanzees have less massive jaws.
Adult chimpanzees have heavier brow ridges.
Adult chimpanzees have flatter faces.
Adult chimpanzees have more rounded faces.


7.  

Click on the diagrams to start the animations.
The differences between chimpanzee and human observed in these animations is attributable to differences in _____. (Activity 24B)

life span
skull structure
bone composition
allometric growth
the appearance of the fetal skulls


8.  

What accounts for human infants having large heads on small bodies? (Activity 24B)

formation of the head before the rest of the body during fetal development
allometric growth
the need to get the infant out through the birth canal
head cells having a different genotype than the cells of the rest of the body
at birth the human head is NOT relatively large compared to the rest of the body


9.  

Variations in allometric growth patterns demonstrate how _____. (Activity 24B)

relatively large genetic changes can have a minor impact on phenotype
relatively small genetic changes can have a major impact on phenotype
chimpanzees and humans could not have a common ancestor
adult chimpanzees are basically juvenile humans that have gained the ability to reproduce
differences in the fetal skulls of chimpanzees and humans lead to very similar adult skulls


10.  

Which of these is a difference between the skull of an adult chimpanzee and the skull of an adult human? (Activity 24B)

The chimpanzee skull is sharper and more angular.
The chimpanzee skull has heavier brow ridges.
The chimpanzee skull has more massive joints.
They result from different patterns of allometric growth.
All of these are differences between adult chimpanzee and adult human skulls.
