| 21. | The newly discovered material probably troubles the established scenario about human evolution and especially evolution of bipedalism,
|
| 22. | Subsequently, older " Ardipithecus ramidus " fossils were found with features that suggest bipedalism.
|
| 23. | Analysis of the footprints and skeletal structure showed clear evidence that bipedalism preceded enlarged brains in hominins.
|
| 24. | They concluded bipedalism was selected simply because it allowed for a further range of travel for hominids.
|
| 25. | Time of origin of bipedalism may well be fifteen million years ago during the miocene ape radiation.
|
| 26. | This environmental theory is used to extend the scope of our understanding of the appearance of bipedalism.
|
| 27. | These tests basically remove any doubt that the origins of bipedalism go back well over four million years,
|
| 28. | However, many anthropologists argue that these advantages were not large enough to cause the emergence of bipedalism.
|
| 29. | Dart's savanna hypothesis suggested that bipedalism was caused by a move to the savanna for hunting.
|
| 30. | Also, basicranial and postcranial remains indicate it may have had adaptations for a significant degree of bipedalism.
