Students have asked these similar questions
Based on height calculations of Homo erectus fossils, biological anthropologists estimate that their average height was
A. Similar to that of Australopithecines.
B. Short, with most being approximately three feet.
C. More than 70% taller than Homo habilis.
D. Tall, within the range of modern humans.
The “cooking hypothesis” suggests that Homo erectus
A. Significantly increased the available food and nutrition and decreased tooth size after learning to control fire.
B. Took much longer to evolve than other hominins because cooking made life much easier and more survivable for them.
C. Started to use fire to keep animals away from their camps, thus allowing them to survive the long African nights.
D. Began to cannibalize (and cook) other hominins, thus decreasing competition and increasing food availability at the same time.

A.
Decrease in the number of incisors
B.
Reduced canine size
