==62:2. THE DAWN MAMMALS==  

62:2.1 A little more than one million years ago the [http://en.wikipedia.org/wiki/Mesopotamia Mesopotamian] dawn [[mammals]], the direct descendants of the North American lemur type of [http://en.wikipedia.org/wiki/Placental_mammals placental mammal], suddenly appeared. They were [[active]] little [[creatures]], almost three feet tall; and while they did not habitually walk on their hind legs, they could easily stand erect. They were hairy and [[agile]] and chattered in [http://en.wikipedia.org/wiki/Monkey monkeylike] fashion, but unlike the [http://en.wikipedia.org/wiki/Simian simian] tribes, they were [[Carnivorous|flesh eaters]. They had a [[primitive]] [http://en.wikipedia.org/wiki/Opposable_thumb opposable thumb] as well as a highly useful grasping big toe. From this point onward the prehuman species successively [[developed]] the opposable thumb while they [[progressively]] lost the grasping power of the great toe. The later [http://en.wikipedia.org/wiki/Apes ape] tribes retained the grasping big toe but never developed the [[human]] type of thumb.

62:2.2 These dawn [[mammals]] [[attained]] [[Maturity|full growth]] when three or four years of age, having a [[potential]] life span, on the [[average]], of about twenty years. As a rule [[offspring]] were born singly, although twins were occasional.
