nearest relatives that are left.
One thing to remember is that what we see today are only the nearest relatives left, those that did not pose a serious threat to modern humans.

Anyone so limited that they can only spell a word one way is severely handicapped!

Re: nearest relatives that are left.
There seems to be a pattern, that every Homo species that has come in contact with Homo sapiens is extinct.

Actually the Neanderthal brain size was very comparable to today's modern Homo sapiens brain size and seem to average slightly larger than Homo sapiens sapiens.

quote:
Abstract

Full brain endocast reconstructions of the Neandertals, Spy I and II, Djebel Ihroud I, and the Homo erectus specimen from Salè, Morocco have yielded accurate volumes. Spy I = 1,305 ml; Spy II = 1,553 ml; Djebel Ihroud I = 1,305 ml; Salè = 880 ml. While there are no remarkable gyral and sulcal patterns one can delineate, the brain endocasts do show evidence of left-occipital, right-frontal petalias, suggesting right-handedness, and possibly human cognitive specialization, involving symbol processing and visuospatial integration. Some speculations regarding Neandertal brain size are also offered, in which it is suggested that their possibly larger brain sizes were related to greater muscularity than in modern Homo sapiens.


From American Journal of Physical Anthropology Volume 55, Issue 3, pages 385–393, July 1981

We know that is your claim, but what is your claim based on?

No Supernatural need apply
Nor is anything outside chemistry and physics needed.

Huh?

Of course scientific facts apply to Crick and Dawkins.

Is that somehow relevant to this thread?

why you consider any opinions
It depends on the content; you test their opinions against reason, logic and reality.
