Evolution, Melanin And Brain Power
There is a whole bunch of nonsense around on the topic of why some people have a lot of melanin and others have little. Melanin is the chemical compound that makes for skin color.
The most common argument is that melanin is somehow affected by heat producing more in the tropics and less in the temperate zones. According to this argument Caucasians are Negroes who have lived in the North for a long time thus losing their melanin. No attempt to offer a mechanism for the process is offered.
The argument can then be used to say that mankind has evolved to a point some hundred fifty thousand years ago when Homo Sapiens severed connections with the Last Hominid Predecessor and no further. A big bronx cheer for that notion.
In fact evolution has been continuing unabated since the LHP. Much of that evolution has been in the development of the capabilities of the brain. Now, when some physical change to an organ takes place the matter for the change must come from the existing reservoir of matter. It is impossible for new matter to be added to the reservoir to facilitate the change.
Thus if some function is added to the brain then the matter to do so must come from somewhere else in the organism. If one organ is increased or added then another must be diminished or eliminated.
Now, if the continuing evolution takes place in one species of Homo Sapiens and not the others that must create a visible physical difference. It has to be.
I am going to suggest that the material for the evolution of the Caucasian brain was provided by the conversion of melanin to the changes in the Caucasian brain. The use of the melanin left the Caucasian White or pale. Thus without the evoltuion of the brain the Caucasian would still be Black while still standing at the intellectual capacity of the Black African.
I don’t need to quote the views of James Watson but there you have it.
Thus the thermometer has nothing to do with skin color but the surfeit or lack of melanin probably has something to do with IQ.
I have said it before and I see no reason as yet to change my opinion, Blacks and Caucasians are two different species of Homo Sapiens or well on the way to being so.
