PLEASE ANSWER IN PARAGRAPH FORM

The fossil and genomic record tell us that our species originated in Africa around 200,000 years ago (These numbers might now go back further). The first 100,000 years were spent in Africa and soon after our species began to expand into different world regions. Your task will be to explore the complex fossil and genetic history of modern humans as they left Africa for the first time.

You can choose one of the following world regions: The Americas (you will be including both North and South), Australia, East Asia, Europe, Pacific Islands.

You will be graded on the following:

All world regions have complicated population histories that are the result of the fact that they are the result of a number of populations that have come together to form the current population. What insight do genomic studies of ancient fossils and modern populations give us in reference to the number of founding populations of your chosen world region?

Make sure you give citations

Explanation / Answer

Fossil evidence from Asian region

Fossils of Homo floresiensis are found in Indonesia (Peter J Obendorf 2008) .They are smaller humans compared to present day humans.Homo sapiens dated to 45000 to 65000 years are found in southeast Asia.Skull bones, jaw bones and teeth are found in Tam Pa ling (TPL) cave ( Demeter et al 2009 ). Genomic studies in this TPL region shows that there is overlapping traits and the frequency of traits varied in the Indochinese peninsular region (Bovin et al, 2013). Modern fossils in the range of 12000 years are also found in china but these fossils are not clear (Saidin 2012) because of the temperature conditions in this region .Human skulls in china , Xujiayao in 1976 (Petraglia et al 2007). In the zhirendong region of china, the fossils are dated back to 100000 years ago.A toe bong which is 65000 year old is found in phillipines (Salvador Mijarus et al 2010). Fossils of Denisovans , who have similar DNA structures as modern humans are also found in East Asia. It is also found that fossil evidence suggests that Denisovans and modern humans interbred(Malaspinas et al 2006).
