Answer:
Since the Fertile Crescent shared that same latitude with Europe and Asia, the people were able to migrate to new areas and thrive.
As different species evolved, it can be seen that those pressures influenced how their cutaneous senses developed through the changes and sensory adaptation. In different climates and situations, one would need to adapt in order to survive. Ex. Someone who works in construction or gardening would develop callouses from the pressure of the tools they use.
Of course it's possible, because it means that sintheta=-2/5 which satisfies this -1<=sintheta<=1
