Describe the factors of biological evolution of humans, Biology

Assignment Help:

Although there are differences in interpretation of the evidence, it is generally accepted that human biological evolution has not been a linear progression from one species to the next.

In fact, there are now thought to have been between 5 and 7 hominin genera, and at several points there have been 2 or more species and  / or genera in existence at the same time. 

Significant factors involved in the biological evolution of humans include:

  • genetic drift
  • natural selection
  • cultural evolution.

Using selected named hominins, discuss how each of these three factors has contributed to the biological evolution of humans.
