Sample text

Furthermore, should there be periods of food shortage that strike during the growth and development of an individual, then the smallerbodied individual has a better chance of growing brain tissue than a large individual. Small body size, while excelling at agility and acceleration, suffers from lower strength, maximum running speed, and endurance. Body mass is thus based on a compromise of factors that allow optimum performance in the tasks demanded by adaptation. The evolutionary road to periglacial environments is virtually a one-way road to herbivores and omnivores.

In the subsequent savanna species the “selfish herd” becomes prominent as a primary security adaptation against predation. This is associated with a dramatic switch in weapon systems and mode of combat. That is, as individuals become gregarious, they fight mainly via wrestling or head-butting, and minimize cuts to the body that could attract predators. They also evolve “sporting” modes of combat, sparring Grzimek’s Animal Life Encyclopedia Vol. 12: Mammals I Ice Age giants matches, in which there are no winners or losers.

However, most of the extant mammals (nearly a half of all genera) maintain the basic mammalian niche. They are terrestrial, mostly nocturnal or crepuscular, and forage for different food resources that are available on the ground. In a tropical forest this may be seeds and fruits falling down from the canopy and the invertebrate or vertebrate animals feeding on them. In the subtropics and temperate regions, the significance of this habitat increases as the soil surface becomes the most significant crossroads of ecosystem metabolism.
