Based on current evidence, Homo sapiens evolved where?

In order for a population to evolve into new species, the following must occur. Choose all statements that are correct.  

Choose the physical features that became increasingly developed through natural selection during hominin/hominoid evolution. 

Natural selection is goal-directed and it results in perfect organisms.

If gametes (sperm and eggs) from individuals in two different populations move between the populations, genetic changes that occur in one population will spread to the other population as well. Therefore, the two populations cannot become genetically different from one another. This scenario explains why:

The biological species concept states that: 

If a specimen label was not completely filled out, which category does that fall under on the occurrence form?

Which of the following tests would be performed in surgical pathology?
