would have been markedly changed. The immediate lemurlike mother of the dawn-mammal species escaped death no less than five times by mere hairbreadth margins before she gave birth to the father of the new and higher mammalian order. But the closest call of all was when lightning struck the tree in which the prospective mother of the Primates twins was sleeping. Both of these mid-mammal parents were severely shocked and badly burned; three of their seven children were killed by this bolt from the skies. These evolving animals were almost superstitious. This couple whose treetop home had been struck were really the leaders of the more progressive group of the mid-mammal species; and following their example, more than half the tribe, embracing the more intelligent families, moved about two miles away from this locality and began the construction of new treetop abodes and new ground shelters—their transient retreats in time of sudden danger.

Soon after the completion of their home, this couple, veterans of so many struggles, found themselves the proud parents of twins, the most interesting and important animals ever to have been born into the world up to that time, for they were the first of the new species of Primates constituting the next vital step in prehuman evolution.

Contemporaneously with the birth of these Primates twins, another couple—a peculiarly retarded male and female of the mid-mammal tribe, a couple that were both mentally and physically inferior—also gave birth to twins. These twins, one male and one female, were indifferent to conquest; they were concerned only with obtaining food and, since they would not eat flesh, soon lost all interest in seeking prey. These retarded twins became the founders of the modern simian tribes. Their descendants sought the warmer southern regions with their mild climates and an abundance of tropical fruits, where they have continued much as of that day except for those branches which mated with the earlier types of gibbons and apes and have greatly deteriorated in consequence.

And so it may be readily seen that man and the ape are related only in that they sprang from the mid-mammals, a tribe in which there occurred the contemporaneous birth and subsequent segregation of two pairs of twins: the inferior pair destined to produce the modern types of monkey, baboon, chimpanzee, and gorilla; the superior pair destined to continue the line of ascent which evolved into man himself.

Modern man and the simians did spring from the same tribe and species but not from the same parents. Man's ancestors are descended from the superior strains of the selected remnant of this mid-mammal tribe, whereas the modern simians (excepting certain pre-existent types of lemurs, gibbons, apes, and other monkeylike creatures) are the descendants of the most inferior couple of this mid-mammal group, a couple who only survived by hiding themselves in a subterranean food-storage retreat for more than two weeks during the last fierce battle of their tribe, emerging only after the hostilities were well over.

Going back to the birth of the superior twins, one male and one female, to the two leading members of the mid-mammal tribe: These animal babies were of an unusual order; they had still less hair on their bodies than their parents
