Question

QUESTION 11

Homo erectus was able to migrate out of Africa because:

		he developed extra body hair to survive in cold areas (like northern Europe)
		he doubled the amount of body fat which provided insulation in cold areas
		by eating meat, he could migrate wherever animals are found, and live in cold areas where plant-eaters (like Australopithecus) could not have found food during Ice Ages
		all of the above

QUESTION 12

Eventually, Homo erectus migrations were limited to certain areas; they could not inhabit certain areas because of a climatic change known as the Pleistocene
which was:

		a period of global warming
		a period of changing extremes, from warm to cold
		an ice age
		an age of desertification (extreme dryness which killed off plant food resources)
		all of the above, at different times

Answer 1

(11)by eating meat he could migrate wherever animals are found,and live in cold areas where plant eaters could not have found food during ice ages.

Homo erectus was the first species to migrate to africa only by following its prey because it did not possessed technical characters like using fire.They just followed their prey and migrated where there was nothing interfering there route.

(12)an ice age

It is a geological epoch which lasted from 2588000 to 11700 years ago spanning the world's most recent period of repeated glaciations.

(13)North America(present canada,USA,and Mexico)

(14)in the americas

There are no evidences of neanderthals in america till now.

(15)shorter and more muscular than modern humans.

They also had many similar anatomical characters to modern humans.
