The origin of species, as well as the origin of the various races under those various species - still is a result of a specific set of processes.
First you need a specie.
Than you may get various types/forms of this specific specie.
With time specific forms would develop into local characteristics - that would grow ongoing generations with the same characteristics. That would define a specific "trail" or "race" from the original line (location) of this specie. That is what we used to call "a race". Today its rather called "sub-specie", although I'm not sure that sounds any better...
Arctic and Tropic
You may find cats and crockodiles of different races - all over the tropical world.
You may find cats and dogs of different races - all over the arctic world.
We may say that there are two (major) types of nature, in biology and botanics is termed as "tropical" vs. "arctical". So we have arctic races and tropical races of cats and dogs - and human beings.
Then we have various trails - as in a number of races - within the arctic as well as the tropical hemisphere. All these "rays" would have emenated from the orginal form of man - that we MAY recognize as "Homo Erectus".
Since the time of early H Erectus the face of the globe have changed a few times. A consequence would be an enduring isolation between various groups that came to inhabbit the various continents, subcontinents and islands and island-groups. As ice-times came and went the contact between larger populations would obviously be obstructed.
What we look for is the original couple that produced our "homo antecessor". That time and history have spread the human family all around the globe and made us look different should not be held against it...
Thus we may allow a scientific observation - of a 900.000 flint-tool - to take precedence over old theories from Leakey and the mere hypothesis' about "migration-patterns". What we just got a look at from South East England (links above) is nothing but an advanced knife ("handsize, two-edged scraper").
Flint is not that commonly found in England, so hopefully a minaral-analyzis of the material could releave its place of origin. Still it belongs to the Mousterian level of tool-making, for sure. The later culture - called "Solutrean" - is nothing but an 'evolutionary' development from the first part of Paleolithicum; of stone-quarries, new tools, improved production-tecniques and a variety of standards within design and decoration.
The English Channel/North Sea is obviously a place were they were able to survive during both cold and warm periods of Paleolithic time. Thus we may find a logic explanation to how these very early Europeans - caugth by the term "erectus" - could have excercised a specific set of cultural skills AND shown a row of very specific, genetic abilities nessecary to survive the arctic wiinter - already 900.000 years ago...?
That would explain the phrase "homo erectus" as something else than "different from us, as in different specie". Now we have to admit that the humans that went skijumping in England already 900.000 years ago had to be rather smart. Moreover they just confirmed that the present Europeans are related to the Neanderthals too.
Perhaps we should rather look at the neander and the other erectus's as different "races" of the Paleolithics. By the end of ice-time we also saw the end of the geographical isolations that have existed during the last million years. Consequently we have seen the peculiar set of greater civilisations that we know to have evolved around political centras on all four continents - as of 10.000 years ago...
During this time of reunification and civilisation the archaic races - from the various continents and subcontinents - got modified. By the growing relationships between the ruling families the inter-change of genetic material would anyway be mixed and ministerd by the contemporary nobility. Thus the genetic exchange within the higher nobility could influence on all the families of Mesolithic Europe - that became Neolithic and Bronze Age Europe and Asia.
To survive under the hostile climate of the arctic the homo erectus would have had to invent a complete new set of skills and social values. The first arctic population would have no one to lean on, nor borrow ideas, find the forms and make a fashions from their neighbours. Since nature hardly makes the same anamoly twice - such as retarded mammals, like the lactose-persistent - we still have to explain how this nature came to produce the pigmentless sub-specie of Homo sapiens, called Caucasians...?!
From what we now know they developed during a refugia in the North Sea - where they seem to have stayed ever since the time they were called Homo Erectus...
