Homo ergaster is a name given by some archaeologists to what others consider to be Homo erectus found in
Africa
The first hominid species to be widely distributed in the Old World was
Homo erectus.
Davidson Black found a Homo erectus he termed
Peking Man.
What characterizes early Homo so that we begin to see the start of new trends in hominid evolution?
a. expansion of the brain c. modification of female pelvis b. general reduction in the size of teeth d. all of the above
Sexual dimorphism in Homo erectus is
about the same as in Homo sapiens.
Among the cultural adaptations Homo erectus may have made is a. use of fire. b. use of clothing. c. better organization for scavenging, hunting, and defense against predators. d. all of the above
all of the above
One early tool of the Acheulian tradition is known as the hand-axe. We think the hand-axe was mostly used for
butchering large animals.
The widening of the female pelvis is related to
c. larger brained babies.
One of the biggest differences between culture and other forms of animal behavior is that in culture, it is learned and shared. Why is this so?
cultural behavior is not innate and it has to be learned
When Homo erectus hunted they may have used fire. How would this be an advantage?
d. animals were driven out of their hiding places into hunters positioned downwind
The creation of home bases or home ranges among early Homo groups may have increased the likelihood of
food sharing.
Generally, the greater the sexual dimorphism, the _________ the social dominance of males over females.
greater
The fundamental difference between culture and most other forms of animal behavior
learned and shared.
Why is there no consensus on how to characterize the Olduvai sites which contain concentrations of stone tools and animal bones?
making tools is a pattern of behavior shared by a group of individuals
According to Theodosius Dobzhansky, socialization and learning processes on which the transmission of culture
the length of the dependency period of human infants.
Archaeologists have experimented with the Oldowan tools. They did this because
they wanted to know what the tools were used for.
Richard Potts suggests that caches of stone tools and stones for tool making were left at various sites in East Africa
to facilitate recurrent food collecting and processing.
We cannot accurately determine the lifestyle of early hominids from early tool sites because
very little else was found with the tools that were dug up.
Acheulian sites were usually located close to
water sources
