  2. Upright walking
  3. Visual surveillance long distance
  4. Walking while foraging and hunting.
(b) The processes that were strengthened by tool making:

  1. Upright walking
  2. Increase in size and capacity of brain
  3. Visual surveillance, long distance walking while foraging and hunting.

Question 3 :
Discuss the arguments advanced in favor of the regional continuity model of human origins. Do you think it provides a convincing explanation of the archaeological evidence? Give reasons for your answer.

Answer 3 :

According to the Regional Continuity Model, the Homo sapiens evolved in different regions at different rates into modern humans. So there was a variation in the first appearance of modern humans in different parts of the world. It was based on the regional differences in the features of present day humans. The advocates of this view found that the dissimilarities are due to the differences between the Homo erectus and Homo heidelbergensis populations of the same regions.
The Regional Continuity Model does not give a convincing explanation of the archaeological evidence.

Question 4 :
Which of the following do you think is best documented in the archaeological record: (a) gathering, (b) tool making and (c) use of fire?

Answer 4 :

Tool making is documented in the archaeological record.

Question 5 :
Discuss the extent to which: (a) hunting and (b) constructing shelters would have been facilitated by the use of language. What other modes of communication could have been used for these activities?

Answer 5 :

(a) Use of language helped hunting activities of human beings in numerous ways:

  1. Now people are in a position of organizing and managing hunting expeditions
  2. They are now free to exchange their ideas about different animals in different regions.
  3. They could now discuss the nature and behavior of animals.
  4. They could now discuss regarding the types of tools to be used.
(b) Language helped in constructing shelters for early humans in the following ways:

  1. Now people could discuss regarding secure and safe places for the construction of shelters.
