1. How might early humans have made tools from stones? 2. If the tools found at Jebel Faya were different to those found in Africa, why would this mean that the two groups of humans using these tools were probably different? 3. The findings of the researchers suggested that early humans may have travelled inland rather than follow the coastlines. Why might the climate at that time have allowed humans to travel inland rather than use the coastlines? 4. Why do you think that humans didn't move from Africa for so many years? What may have caused them to begin moving out of Africa? 5. The archaeologists who worked on the exploration of Jebel Faya believed that the tools they found were similar to those found in parts of Africa. Why do you think this would suggest that people must have travelled from Africa to Arabia? I know this is a lot to ask but i'm really looking for help, So pleaase help me

1. Knapping

2. Different technique implies different people

3. The desert areas of nowadays Arabia were once green areas.  

4. Food shortage and/or climate changes

5. See explination nr. 2

Explanation:

1. 'Knapping' is the process of knocking of flakes of a stone.

2. Theories of archeologists are very often based on (logic) assumptions. When there is a certain stone tool technique in one and another in a different place, they assume they must be from different people.

3. The migration by land was made possible through climate changes that ranges from an ice corridor that once connected Alaska with Iberia, to more hospitable environments of lakes and rivers with an abundance of plants and animals in what is now the Arabic desert.

4. The same climate change (warming up) that caused more hospitable environments - deeply connected with foodsupply - along the mediterranean sea might have caused a dryer and less hospitable environment in East Africa.

5 is answered the same way as question nr. 2 but now with the same tools, and thus the same people who must have traveled.

P.S. Archeologists agree on the emigration of early humans from Africa to other continents; they don´t agree on When. Genetic study claims that it was about 60.000 years ago, but the findings at Jebel Faya and other places suggest that this might have happened (much) earlier.
