The Six (6) Physical Transmutations of the Human Family

There are many different lists of human developments.  The great Senegal scholar, Dr. Cheikh Anta Diop, has one of the most clear and concise levels of Humanity’s physical, mental and spiritual growth.  He identifies two lines of Australopithecine and four forms Homo Humans.  In Dr. Diop’s book, Civilization or Barbarism, he cites,

The Six (6) Physical Transmutations of the Human Family

Australopithecine Line

1. Australopithecus Robustus (Robust)
2. Australopithecus Gracile (Slimmer than Robust/Graceful)

Homo Line

3. Homo Habilis (Tool maker)
4. Homo Erectus (Human Standing Erect)
5. Homo Sapiens (Thinking Human)
6. Homo Sapiens Sapiens (Creative Thinking Human)

Scientific Studies develop an understanding of the role of climate on pigmentation, physiology (physical appearance) and morphology (body type).  The following three rules explain some of these concepts.

-Gloger’s Rule – named after zoologist Constantin Wilhelm Lambert Gloger, who first remarked upon this phenomenon in 1833 in a review of covariation of climate and avian plumage color.

-Allen’s Rule - Allen’s rule is a biological rule posited by Joel Asaph Allen in 1877.  

It states that endotherms from colder climates usually have shorter limbs (or appendages) than the equivalent animals from warmer climates.

Allen’s rule states that endothermic animals (mammals and birds) with the same volume may have differing surface areas, which will aid or impede their temperature regulation.

-Bergmann’s Rule - Bergmann’s rule is a zoological rule named after a biologist named Christian Bergmann who first formulated the rule in1847.

It is an eco-geographical rule that correlates latitude with body mass in animals.  Broadly it asserts that within a species the body mass increases with latitude and colder climate, or that within closely related species that differ only in relation to size that one would expect the larger species to be found at the higher latitude.  The rule is often applied only to mammals and birds (endotherms), but some researchers have also found evidence for the rule in studies of ectothermic species.  

Another relevant scientific principle important to human development is the role that the bio-chemical 7-Dehydrocholestrol plays in the production and distribution of Vitamin D3 and calcium in the human skin and body.

7-Dehydrocholestrol is a biochemical substance.  It is a zoosterol.  Sterols or steroid alcohols are a subgroup of steroids.  Sterols of plants are called phytosterols and sterols of animals are called zoosterols.  An important sterol is “cholesterols”.  Cholesterol is a lipid found in the cell membranes of all animal tissues, and is transported in the blood plasma of all animals.  Cholesterol is also a sterol (a combination steroid and alcohol).  The name originates from the Greek chole=bile and sterols=solid and the chemical suffix ol=alcohol.

7-Dehydrocholestrol functions in the serum as a cholesterol precursor, and is converted to pre-vitamin D3 in the skin, therefore functioning as pro-vitamin-D3.  The presence of this compound in human skin enables humans to manufacture vitamin D3 from ultra-violet rays in the sunlight, via an intermediate isomer pre-vitamin D3 (Cholecalciferol).  It is also found in the milk of several mammalian species.
