there appears to be no change in jaw size over time
the jaw size decreased and allowed for increased brain size
the jaw size grew bigger and more pronounced over time
the jaw size became larger and more protruding, allowing for increased brain size

Answer 1

The statement that most closely explains the link between jaw size and hominid evolution is:

"the jaw size decreased and allowed for increased brain size."

This reflects the trend in hominid evolution where a reduction in jaw size was associated with an increase in brain capacity, as dietary changes and tool use allowed early hominids to require less robust jaws.
