Instead, it is much more likely that extant human P. vivax represents a lineage that survived after spreading out of Africa. This scenario explains the reduced diversity of the human parasites as resulting from an out-of-Africa bottleneck, as seen in P. falciparum ( Conway et al., 2000 ; Tanabe et al., 2010 ) and in humans themselves ( Ramachandran et al., 2005 ).

2 de jul. de 2016 · Plasmodium falciparum is highly prevalent in sub-Saharan Africa where it is responsible for nearly 200 million clinical cases ( Bhatt et al., 2015) and over 300,000 malaria-related deaths annually, predominantly in children under 5 years of age (World Health Organization, 2015). Plasmodium vivax is rare in sub-Saharan Africa, but endemic in ...
Out of Africa or single origin model. The ‘Out of Africa’ model was the most widely favoured explanation accounting for the origins of modern humans. It suggested that modern humans originated in Africa within the last 200,000 years from a single group of ancestors.
However, in arguing for African ancestry, neither Protsch nor Bräuer contended that early humans of modern form in Africa implied unique African origins. The Out of Africa hypothesis— the idea of an African origin for a recent modern human species—owes its genesis to interpretations of mtDNA, which suggested that the ancestors of recent ...
