Changes

62:3.6 [[Compared]] with the [[ancestral]] [[species]], the mid-mammals were an improvement in every way. Even their [[potential]] life span was longer, being about twenty-five years. A number of rudimentary [[human]] traits appeared in this new species. In addition to the [[innate]] propensities exhibited by their [[ancestors]], these mid-mammals were capable of showing [[disgust]] in certain repulsive situations. They further [[possessed]] a well-defined hoarding [[instinct]]; they would hide [[food]] for subsequent use and were greatly given to the [[collection]] of smooth round pebbles and certain types of round stones suitable for [[defensive]] and offensive ammunition.

62:3.7 These mid-mammals were the first to exhibit a definite construction [[propensity]], as shown in their rivalry in the building of both treetop homes and their many-tunneled subterranean [[retreats]]; they were the first [[species]] of [[mammals]] ever to provide for [[safety]] in both [[arboreal]] and underground shelters. They largely forsook the [http://en.wikipedia.org/wiki/Trees trees] as places of [[abode]], living on the ground during the day and [[sleeping]] in the treetops at night.

62:3.8 As [[time]] passed, the [[natural]] increase in [[numbers]] [[eventually]] resulted in serious [[food]] [[competition]] and [[sex]] [[Competition|rivalry]], all of which culminated in a series of internecine battles that nearly destroyed the entire [[species]]. These [[struggles]] continued until only one [[group]] of less than one hundred [[individuals]] was left alive. But [[peace]] once more prevailed, and this lone [[surviving]] [[tribe]] built anew its [[treetop]] bedrooms and once again resumed a [[normal]] and semipeaceful [[existence]].
