John Hawks, on the chimpanzee .... "I am inclined toward an alternative interpretation. The reason there weren't chimpanzees in East Africa in the Pliocene is...
... OK. On a related point, can I ask why you consider the habilis to be the first of genus Homo? When it is known to have co-existed in the same part of...
... Yes, or rel.thin (Oreop): they have nothing to do with Homo, they were possibly more folivorous. Most early apes had thick enamel: in this respect Hs & Po...
... MW: Oreopithecus, Sahelanthropus, and Ardipithecus all had intermediately thick molar enamel-- not thick molar enamel. Australopithecus and Homo had thick...
... No, no, Marcel: apiths are less derived (still thick enamel, bunodont cheekteeth, shorter arms & hands, more vertical & bipedal locomotion etc.) than...
... MW: That's not very likely since Pan shows very few cranio-dental and postcranial similarities with Australopithecus. It would also require the ancestors...
Human-specific transcriptional regulation of CNS development genes by FOXP2 Export G Konopka cs 2009 Nature The signalling pathways controlling both the...
... If the Ardipithecus were in that particular area, I agree it is likely that a number of them would have been likely to have survived on the 'island' ... it...
... MW: Ardipithecine fossil remains are found as early as 5.6 million years ago and as young as 4.3 million years ago. And they are the only hominin known to...
The first Oldowan tools ever discovered were initially associated with Paranthropus (Zinjanthropus) boisei until Homo habilis remains were finally discovered...
First of all, I assume that any hominins that did survive the flooding of the Red Sea were confined to the largest island in the Afar/ Red Sea region. And this...

... Elaine, Yes, Darwin did not coin the phrase "survival of the fittest" himself that 'honour' goes to one of his colleagues - Herbert Spencer who coined it...
... Thanks for ref., Marcel There is a good illustration of a possible island on page.9 of your paper ... Afar island ... it would appear to be roughly 20/25...
... A map of the Northern Afar region during the Early Pliocene can be found in the files section in my 2006 paper 'Morphological evidence of marine...
... Not necessarily ... Darwinian survival of the fittest ("only the fittest organisms will prevail") would work to eliminate those mildly deleterious...
... Would agree not all high ground would have become islands when the Red sea flooded, but if the area was roughly the same as it is today those areas north...
... Morning Algis, 3.5 Mya seems to have been sufficient time for human and chimpanzee to be distinct species some two million years ago, when H.erectus was...
