Firstly, adaptation is age-specific, with Hamilton\u2019s forces of natural selection leading to much greater adaptation at earlier ages than later ages. This of course is how evolutionary biologists explain the existence of aging in the first place. Secondly, when environmental conditions change, it takes surprisingly few generations for populations to adapt to such new conditions, at least at early ages when natural selection is intense. Thirdly, at later ages, when the forces of natural selection are weak, natural selection will often fail to produce adaptation to a selective environment that is not evolutionarily ancient. All three of these themes will be illustrated using both explicit mathematical theory and findings from experimental evolution. At the end of the presentation, we will apply these general scientific insights to the case of human evolutionary history, human aging, and optimal human diets.<\/p>\n<p><!-- Link: <a href=\"https:\/\/www.youtube.com\/watch?v=4-9S8M78iRY&feature=youtu.be\">https:\/\/www.youtube.com\/watch?v=4&#45;9S8M78iRY&feature=youtu.be<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Human health depends on age and evolutionary history.
