A popular explanation for why
H. erectus/ergaster
was the first hominin to leave Africa is that they:
A/ were the first hominin to develop boat technology.
B/ were well adapted to savannah grasslands which spread all the way to China at this time.
C/ were the first species to develop effective clothing for use in colder latitudes.
D/ were chased out of Africa by
Gigantopithecus
.

The evidence from Dmanisi that early hominins took good care of older members of a group is:
A/ cut marks on the skull of an old man indicating corrective surgery.
B/ the skeleton of an old man who had lived for decades after losing all his teeth.
C/ the skeleton of an old man who had lived for decades after losing a leg.
D/ the discovery of the remains of an old man in an elaborate grave.

‘Biochronology’ refers to:
A/ using rates of change in DNA to date the evolutionary split of related species.
B/ the order of the evolution of related species, as presented in hominin phylogenetic trees.
C/ changes in plant and animal ecosystems following climatic changes.
D/ the use of changes in extinct species of animals to date associated hominin sites.
58.
The most widely accepted explanation for the small size of
Homo floresiensis
is:
A/ the well-known evolutionary phenomenon “Arboreal Dwarfism.”
B/ that they directly evolved from Australopithecines who were almost as small.
C/ the well-known, though rare, pathology called ‘Microcephaly.’
D/ the well-known evolutionary phenomenon “Island Dwarfism.”

Traits, like body hair coverage, that can change relatively quickly in response to changing environments and changing selective pressure are called:
A/ Apomorphic traits.
B/ X-men traits.
C/ Plastic traits.
D/ Polymorphic traits.

Homo habilis
was originally seen as a likely candidate for the earliest stone tool maker because:
A/ cut marks have been found on animal bones in
Homo habilis
sites.
B/ they appear about the same time as stone tools, have larger brains, and modern-looking hands.
C/ cut marks have been found on their hand bones.
D/ theirs are the only fossil hominins found near the sources of stone used for making tools.
