There are two hypotheses to explain the pattern of Human Evolution:
1) Progressive Evolution of a Single Lineage ; 2) Evolutionary Radiation
Which of these hypotheses are supported by evidence, and briefly explain why?
Homework Answers
The progressive evolution and the evolutionary radiation (adaptive radiation) are the hypothesis to explain the patterns of evolution.
Human evolution cannot be called as adaptive radiation. Because,Adaptive radiation is an evolutionary process that a small number of ancestral species in one taxon diversifies into a larger number of descendant species, occupying a broader range of ecological niches, which is not in the case of human evolution.
Human evolution is an example of ORTHOGENESIS or ANAGENESIS which is a gradual process that took place slowly in time.
