In anotherchapter, you will learn of evidence that primates, especially fossil species in the Hominin group that apparently led to our currentHomo sapiens sapiensspecies identity. Many of the fossils of pre-human species have been found where geologic evidence indicates changes in climate, habitat, and terrain. The theoretical relationships among the earlier “human” populations in response to changes, support
- punctuated equilibrium, allowing selection that favored different traits of body form.
- gradualism, allowing species to develop mutations and gene pool changes at a uniform rate.
- sympatric speciation, as the populations had to initially coexist before they diverged geographically from each other.
- parapatric speciation, where the survival of the populations had to rely on slow growth of their ranges.
- None of these answer options are supported by evidence in human evolutionary theory.
