What Processes May Have Caused the Changes in Hominin Morphology

Question

Examlex · Accepted Answer

The Answer is Several processes may have been at work during the Pleistocene to spur the changes in morphology and technology:
a. Continual climatic change would have created new selection pressures;
b. Tool technologies may have been adaptive modifications in particular regions of the world. For example, in Africa, there may have been slow, gradual change through the modes of tool production; and
c. Repeated invasions by later populations of hominins from Africa could have replaced those in Eurasia. Technological shifts in Eurasia seem to be timed with interglacial periods when hominins could have migrated out of Africa and into Eurasia.
