article_snippet: The evidence also suggests that big bodies and long legs were not prerequisites for spreading out of Africa into Europe and Asia.
article_snippet: The evolution of larger bodies and longer legs can no longer be assumed to be the main driving factor behind the earliest excursions of our genus to Eurasia,' said co-author Manuel Will, from Tubingen University in Germany.
article_snippet: geographical trends for the evolution of body size among early Homo….suggesting that migrations into Eurasia were not contingent on larger body sizes,’ the study says .
article_snippet: Body size has been implicated as a factor contributing to both brain evolution and the first hominin dispersals into Eurasia .
article_snippet: One argument suggests that as lower limbs lengthened and hominins assumed limb proportions more similar to modern humans, they became more mobile and changed they foraging behaviour and diet.
article_snippet: By this point, the dispersals already happened, suggesting that migrations into Eurasia were possible without a significant increase in body size and possibly lower limb length.
highlights_snippet: It has been said ancestors left Africa as a result of developing longer legs .
