Mesowear study of ungulates from the early Pleistocene site of 'Ubeidiya (Israel) and the implications for early Homo dispersal from Africa

Results do not support the notion that 'Ubeidiya was an open grassland habitat during the early Pleistocene and hominins did not preferentially occupy such environments. Thus it the adaptability of Homo to novel habitats out of Africa lend support to the climate variability hypothesis.
