Who proposed the patchy forest hypothesis?

Peter Rodman
Peter Rodman and Henry McHenry’s Patchy Forest Hypothesis i. Human origins and bipedalism related to the greater efficiency in some habitats of moving on two limbs rather than four. ii. Bipedalism arose in areas where forests were fragmented and food resources also became scattered.

What caused bipedalism in humans?

There are different hypotheses that explain how and why bipedalism evolved in humans. The possible reasons for the evolution of human bipedalism include the freeing of the hands to use and carry tools, threat displays, sexual dimorphism in food gathering, and changes in climate and habitat (from jungle to savanna).

How is a theory different from a hypothesis?

In scientific reasoning, a hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: it’s a principle formed as an attempt to explain things that have already been substantiated by data.
