For the 1st thirds of our evolutionary heritage, we hominins have been constrained to Africa. relationship from approximately million years in the past, hominin fossils first seem in Eurasia. This quantity addresses some of the concerns surrounding this preliminary hominin intercontinental dispersal. Why did hominins first depart Africa within the early Pleistocene and never past? What will we find out about the diversifications of the hominins that dispersed - their vitamin, locomotor skills, cultural talents? was once there a unmarried dispersal occasion or a number of? was once the hominin dispersal a part of a broader faunal growth of African mammals northward? What direction or routes did dispersing populations take?

Panthera cf. P. gombaszoegensis is found at this site, but no mention is made of what distinguishes UB 307 from this species of Panthera. Interestingly, Palmqvist et al. (2007) list measurements for an unpublished lower canine from 'Ubeidiya (presumably UB 14) and include width and breadth measurements that are larger than some of their M. cultridens measurements (thus suggesting their assignments of canines to species are based on something other than size). While they do not include measurements of the upper canine from 'Ubeidiya, their measurements of upper canines do not distinguish M.
How important that resource was to migrating hominins is unknown. It seems doubtful that this would be the only factor 24 or even the dominant factor enabling hominin migration out of Africa. For reasons mentioned above, regular, confrontational use of this source of carcasses might cause the resource to disappear. While there may have been few species actively dispersing from Africa to Eurasia at this time, there were indigenous species that hominins would have encountered as they moved northwards.
