Anthropology Question and Answer

 

 

Question: How did hominins adapt to the different phases of the Pleistocene period, both culturally and physically?

  1. I was surprised by the transformation of Africa between the glacial and interglacial period. Africa, unlike Europe, which lost its glaciers from the changing environments, because more habitable with increased rainfall and better vegetation. The transformation indicates why Africa has more favorable environments and climate that can support both wild vegetation and animals. The changing Pleistocene surroundings in Africa were associated with colder temperatures in the northern part of the continent and arid conditions in the southern region during the glacial period. The interglacial period warmed the temperatures in the northern latitudes and made the southern latitudes wetter. Consequentially, the extensive Saharan desert faded over time with forests and green vegetation sprouting due to the increased rainfall (Chapter 10, pp. 9-11). The changing environments in Africa were different from Eurasia in that during the glacial period, Eurasia comprised of a Scandinavian continental glacier and during the interglacial period, the glacier shrunk in size, allowing Eurasia to be more hospitable to hominins. Europe thus became densely populated in the interglacial period.
  2. The major contradiction between the replacement model and global continuity model is that the first human being came from Africa. The replacement model utilizes the “Out of Africa” perspective in which all people in the world are believed to have a common ancestry from the continent, while the global continuity model asserts that every group of persons has an antiquity, which means that the Chinese emerged from an ancestor in their region and the Africans arose from a different ancestor from their region. The conceptualization of the global continuity framework aids in understanding regional varieties as products of subsequent regional species. However, by incorporating regional diversities, the model interferes with the evolution myth of gene flow and replacement of people over time for better and more adaptable species. I support the replacement model because a lot of anthropological evidence is available to suggest that Africa was the homeland for modern hominins from the Dmanisi discoveries to the Nariokotome skeleton (Chapter 9, pp 19-30).
