Reproductive strategies are major contributors to evolutionary fitness and can vary substantially between species.
He explains how aspects of political conservatism, namely tribalism, emphasis on female sexual control, and its hawkish and territorial nature, are rooted in male mate competition, and how the roots of liberalism come from efforts to rein in dominant males and prevent them from monopolizing resources and impinging on the evolutionary fitness of those with less power, and how it is based on the task of rearing offspring.
Synopsis: In "The Awakened Ape: A Biohacker's Guide To Evolutionary Fitness, Natural Ecstasy, and Stress-Free Living", author Jevan Pradas uses evolutionary psychology to hack the human mind and body to answer the question: "How can we enjoy life to the fullest?" The results, while unexpected, are completely backed by science.
Dynamic capabilities exhibit technical fitness if they lead to intended outcomes, and evolutionary fitness if they secure a firm's success in the marketplace (Helfat et al.
One theory is that these traits suggest something about the male bird's evolutionary fitness: a brightly coloured bird might be healthier, a good dancer, quick and dexterous; a guy with a beautiful bower clever enough to keep his house in order.
Coming to additionally believe that one's pain is bad for one would seem to add little or nothing to one's tendency to avoid such feelings, and so to one's evolutionary fitness. Indeed, in creatures who already hate their own pain, adding a belief in the badness for them of pain might, at least in certain circumstances, reduce their fitness by leading them to focus excessively on immediate pain relief to the exclusion of more important things (such as the survival or flourishing of kin or certain long-term interests of their own).
One could ask, of course, why are we excited about the studies of these long-lived mutants if their evolutionary fitness is more likely reduced than enhanced?
"We think we know a lot about the biology, but surely we don't know everything." Synthetic chromosomes that damage yeast's evolutionary fitness or fail to produce viable yeast may teach researchers how chromosomes evolved and give clues about the minimal requirements for eukaryotic life, he says.
"We now know that "altruistic" helping can actually increase evolutionary fitness in various ways - people might preferentially help their relatives, with whom they share genes, or they might target their helping toward others who are likely to reciprocate in the future."
dentricus is particularly important to understanding the evolutionary fitness costs of sexual versus asexual reproduction as Maynard Smith's "cost of males" only applies if the offspring produced by asexual reproduction have the same fertility/ hatchability as the offspring produced by sexual reproduction (Bergerard 1958).
By 'becoming' media, we enhance our understanding and, as a consequence, our evolutionary fitness. Whether media or humans are the symbiotic driver of what might broadly be referred to as 'technological' selection is, however, left open to debate.
"Somehow you have the impression that there is some reality attached to it, but the actual mathematical description of any evolutionary process shows that evolutionary fitness is an unnecessary concept."
