JW: Thank you Dan. I'm sure you are just the man I need to
sort this out.

If H. erectus was a warm temperate adaptation, and H.
neanderthal was a tundra adaptation, was there a cold
temperate adapted hominid? And if so, what is its modern

JW: In view of what Anton Uriarte has said concerning uvb
radiation, do you think that the H. neanderthal followed
the usual altitudinal-latitudinal route from the equatorial
tundra altitudes to the tundra latitudes? Or do you think
H. neanderthal's adaptation was a purely regional

JW: I'm thinking here of elimination of competing
predators, which is well documented in the historical
record. If this started as a behavioural adaptation at the
inception of evolution, the resulting expansion of
prey animals could have severely disrupted the floral
ecologies -- with a consequential impact on contemporary
hominid specie.

Am I right in thinking that many competing predators became
extinct during the first 100 kyrs of existence?
