Consider that you just have been requested tips to verify human survival. the place may you start? Conservation of assets jumps to brain. we have to preserve assets so that fiscal actions could proceed. lamentably, this can be a fake begin. assets are continually outlined by way of a given financial system, and merely it determines what's and what's no longer a source. for this reason, holding assets implies simply the perpetua­ tion of the fitting economic climate. Conservation of assets as we all know them has not anything to do with the survival of mankind, however it has a great deal to do with the survival of the economic procedure and society we are living in this present day. we need to commence, accordingly, at a extra uncomplicated point. This point, a few might argue, is addressed by means of making sure for humans "clean genes. " back, this can be a incorrect starting. it really is completely mistaken-for purposes of technological know-how. it's a fake begin simply because malfunctioning organs and morphological constructions usually are not basically because of deleterious hereditary components yet rather because of adverse environments in the course of early progress and improvement. in addition, eugenics isn't applicable to any yet a small fraction of society. Eugenics will not be beside the point to our destiny, yet is untimely and may be of little problem till we know how human genes and setting interact.

Moreover, a knowledge of it permits insights into the process of communication and its limitations, and sheds some light on environments we can and cannot cope with. It gives insight into goal-directed behavior, as well as the old nature-nurture controversy, and lays the groundwork for the following chapters dealing with aggression and status displays. The following will not be an exhaustive review of the speculative subject of the physiology or, better still, "natural history" of cognition. Rather, it will be a sketchy review with emphasis on aspects that pertain directly to a better understanding of the rules governing the life of higher creatures such as ourselves.

We are dealing here primarily with parental investment, a subject formally and elegantly treated by Trivers (1972, 1974) and Trivers and Willard (1973) (see also Wilson 1975). Trivers' model is a powerful predictor of the behaviors of males and females according to the amount of resources each sex invests in offspring; it permits one to evaluate the costs and benefits of various strategies of reproduction and predict the actions of the male and female, as well as that of the offpsring, and even the sex ratios of offspring most likely to be produced by individuals.

Also, in kin-selected populations, there ought to be group actions in which individuals perform actions in harmony. The harmonious performance of individuals in schools of fish or flights of birds should not be confused with the above-mentioned performances. Schools and dense swarms of birds appear to be adaptations against predators (see Wilson 1975, p. 38); perfect close-order drill, and thus acting as a unit, is advantageous to individuals, since in so doing they avoid acting discordantly and being at once selected and pursued by a predator.
