Describe the specific changes to the brain and skull first seen in archaic Homo sapiens. Why does the shape of the skull change so dramatically from Homo erectus?
Homework Answers
The cranial capacity of archaic Homo sapiens was from 1200-1400 c.c. and they were different from modern human in skull structure by possessing thick skull with prominent supraorbital ridges and lack of prominent chin.
Brain size in archaic Homo sapiens expanded from 900 c.c. in homo erectus to 1300 c.c.
This dramatic change of skull size was necessary for the cognitive and speaking skills which made their survival better. They used to live in groups of approximately 120 individuals as they had developed language skills.

Until recently, there were two competing theories about the
origin of our species- "modern Homo sapiens". The first (single
African origin) is that all modern humans descended from a recent
ancestor in Africa, less than 200,000 years ago, and that our
ancestors replaced the archaic human species they found in their
migrations, including Neanderthals and Denisovans. (In the last few
years evidence from nuclear genomes of fossil humans has indicated
that there was limited interbreeding between the ancestors of
modern...

Essay: Homo erectus differs from earlier hominins in having a subsistence pattern that includes higher amounts of meats and foods that required extractive foraging. 1) Describe the relationship between brain size, body size/limb proportions and this shift in subsistence patterns for H. erectus. Be sure to include specific references to biological adaptations related to the subsistence pattern. 2) How does culture (think stone tools and social behaviors) influence these factors? Your answer should include a definition/discussion of the biocultural feedback...

Topic 4 -- How does the fact that humans ancestors seem to have always moved around the globe help argue that the “Regional Continuity Model” is plausible? Be specific using language from genetics. Regional Continuity advocates claim that gene flow helps explain the differences between local populations around the globe. O Regional Continuity advocates describe gene flow as a main feature of why modern H. sapiens are so similar today. With interbreeding between migrating H. sapiens and the local populations,...

Until quite recently, aprominent hypothesisin the origin of humans was that bipedalism and increased brainsizeevolved simultaneously. What evidence is calling this hypothesis into question now? 13.
