Peter Andrews discusses the Middle Pleistocene specimens from Java and China, and earlier Pleistocene forms ER 3733 and 3883 from Africa, and the later European and African forms such as Arago, Heidelberg and Broken Hill (Rhodesian Man).79 He claims the African specimens may represent different species or a separate lineage from Asian forms giving rise to separate populations of H. sapiens in the later Pleistocene - that is, Solo Man from Java may be directly ancestral to the controversial Kow Swamp and Cossack erectus / sapiens populations in Australia about 6,000 - 13,000 years ago.

Some studies have investigated how the competition with H. sapiens may have caused Neanderthals» extinction.

Rules of nomenclature say the species name technically can not be used without the genus name - so we are not sapiens, we are Homo sapiens (which can be abbreviated H. sapiens).

But it also resembles H. sapiens, with its smaller teeth and bigger braincase.

Those who see it as a valid taxon tend to see it as more closely resembling modern H. sapiens than does H. erectus.

Another problem is that Lubenow arbitrarily assigns to H. sapiens many fossils which either belong to H. erectus or other species, or are not readily identifiable.

They posit Neanderthal extinction occurring around 39,000 years ago and raise the possibility the period of contact between H. nenderthalensis and H. sapiens entering from Africa could have been as brief as a few hundred years and was no greater than 6000 years instead of the previously accepted 15/20, 000 years.

The regional differentiation between African and Asian H. erectus populations, and the eventual transition of the former into H. heidelbergensis, and between H. sapiens and H. neanderthalensis suggests that there was limited gene flow between Africa and Asia.

The Maludong endocast is broader and taller than the Chinese Pleistocene H. sapiens cranium from Liujiang (breadth 115 mm, height 95 mm), and much broader than the endocast of the late Upper Pleistocene Japanese Minatogawa I cranium (112 mm).

Another possible explanation is that the unusual morphology of the Longlin and Maludong remains results from the retention of a large number of ancestral polymorphisms in a population of H. sapiens.

The partial human skull from Longlin Cave and the human calotte, partial mandibles and teeth from Maludong both present a range of individual features and a composite of characters not seen among Pleistocene or recent populations of H. sapiens.

Ice age conditions may have driven the H. sapiens in what is now China to live and mate with Denisovans.

Even if there was no fossil evidence of the evolution from H. erectus to H. sapiens, Goodman's theory would be unconvincing.

Goodman ignores most of them, but misrepresents at least one: he calls the Rhodesian Man skull a late - surviving H. erectus, when it is, at 1280 cc., larger than any erectus skull and falls nicely into the morphological and temporal gaps which he claims separate H. erectus and H. sapiens.

Another oddity is Goodman's claim that the coexistence of two species (specifically, H. erectus and H. sapiens) shows that they can not have an ancestor - descendent relationship.

The bones came from an ancient species that looked much like H. sapiens, a team of scientists now reports.

Goodman points out, correctly, that the brow ridges of Homo erectus are more massive than those of H. habilis and H. sapiens and that this constitutes an evolutionary reversal, but says that:

«There is no evidence that this cranium particularly resembles H. sapiens or H. erectus according to either phenetic or cladistic evidence.

These skulls are intermediate between H. erectus and H. sapiens in morphology, time, and brain size, nicely filling the gap which Goodman claims exists between them.

It's possible that those H. sapiens looked different than others.

In contrast, Neanderthals show relatively thin enamel in their incisors, canines, premolars, and molars, although incisor AET values are similar to H. sapiens.

afarensis) were comparable with later Homo species, including H. erectus s. l. and H. sapiens.

Although H. sapiens might have emerged in East Africa, some researchers also categorize a previously discovered fossil skull from South Africa, tentatively dated to about 260,000 years ago, as H. sapiens.

The Jebel Irhoud lower jaw also shares much in common with H. sapiens.

Facial and dental traits of H. sapiens were established by around 300,000 years ago, whereas brain shape has continued to evolve since then, the researchers propose.
