摘要: After having traveled from ecology to physiology, endocrinology, metabolism, and immunology, we will return once again the basic drawing board of ecology. Ecology evolution are foundations all these arguments, one should not lose touch with foundation at any time. The dynamics populations is a very fundamental process evolution, it certainly important in physiology medicine too, but its importance appreciated sufficiently areas science. Population level processes individual’s behavior have subtle far-reaching influences on each other, this an area that has yet received sufficient attention. Ecologists realized [1–3] some extent, physiologists paid attention it. I would attempt make case below for why how population bound affect individual need understand processes. If am able convince reader about point, logically follow today’s unprecedented density human supernormal stimulus could change as well substantially, ultimately consequences health.
