[QUOTE]Originally posted by zarahan- aka Enrique Cardova: [QB] Perchance spontaneously when the Celestials landed to... well Marvel fans would know.. :) ------------------------------------------------------------- But one clue, anyhow... "Tracing the paths of modern humans from Africa "In the 1980s, genetic and fossil evidence began to call attention to Africa’s preeminence in the origins of modern human populations (1), but this evidence could be interpreted in two fundamentally different ways (2). Was Africa’s role greater than other continents because it always harbored a larger human population (size) or because modern humans arose in Africa first and subsequently expanded their range across the world (time)? In the 2000s, improvements in DNA sequencing technology and genetic sampling of more present day human groups made it possible to accurately characterize the genetic diversity of groups from different regions of the world, and it became clear that within- group genetic diversity decreased predictably with increased geographic distance from sub-Saharan Africa (3, 4). Subsequently, similar, albeit weaker, relationships were found between within-group variation in aspects of skeletal morphology (cranial, dental, and pelvic measurements) and distance from sub-Saharan Africa (5⇓⇓–8)." --Weaver 2014-Tracing the paths of modern humans from Africa-PNAS v111-n20,7170-7171 [/QB][/QUOTE]
