it means that you can change the course of history for your Offspring based on your exercise and your diet and whether you're drinking or not and what 00:35:59 kind of habits
for - explanation - lay - natural selection happens by epigenetic change first
explanation - lay - natural selection happens by epigenetic change first - The change in narrative has enormous ramifications. - It means that you can change the course of history for your offspring based on: - your exercise - your diet - your drinking habits - and many other behavioral and lifestyle choices and environmental explosure you exist in

it's an advantage for epigenetic changes to be temporary because if the environment is only a temporary change you can forget about it if the environment is 00:35:19 longlasting it can get a similation in the genome and you've got speciation that's the extraordinary thing natural selection is not the origin of speciation it's epigenetics 00:35:34 followed by the genetic changes the epigenetic leades

key insight - natural selection happens by epigenetic change followed by genetic change - It's an advantage for epigenetic changes to be temporary because - if the environment is only a temporary change you can forget about it - if the environment is long lasting it can get assimilation in the genome and you've got speciation - That's the extraordinary thing - natural selection is not the origin of speciation, - it's epigenetics - followed by the genetic changes - The epigenetic leads - therefore, the environment leads

We might view human social organization in general in this lens: social organization exists to maximize the extraction of energy from the environment to the group and individual (X), and the efficiency of the conversion of extracted energy into offspring (E). This is identical to the claim that social organization exists to maximize the fitness of the group (Wilson and Sober 1994) and/or the individuals which compose the group (Nowak et al. 2010), given an energetic definition of fitness.

Ricklefs and Wikelski 2002)]. In this context, Pianka (1970) argued that, “…natural selection will usually act to maximize the amounts of matter and energy gathered per unit time.” Brown et al. (1993) likewise offered an energetic definition in which fitness is “reproductive power, or the rate of conversion of energy into offspring.” This reproductive power was taken to be a function of both the rate of assimilation of energy from the environment and the rate of conversion of energy to offspring (but see (Kozlowski 1996)).
