Epigenetics: Why Inheritance Is Weirder Than We Thought

YouTube Description:

Want to learn more about the topic in this week’s video? Here are some keywords/phrases to get your googling started:

epigenetics: genetic control by factors other than an individual’s DNA sequence

epigenetic inheritance: transmittance of information from one generation of an organism to the next that affects the traits of offspring without altering the DNA sequence

So, the survivors of a famine (ie. the strongest ones) had strong children? There could be another explanation besides epigenetics...

I see what you're saying, but I'm assuming they controlled for this in their research. Epigenetics is really interesting, as people used to think the germ line was untouchable.

Exactly! the implications are huge in the understanding of evolution and even society, since say, the selfish gene in humans/red hair/disease/etc can be triggered or turned off, or say that there is an extra feedback mechanism in males´offspring! It could explain the enormously fast adaptability in the evolution of species and the programmed role of males in society and their EXPERIENCES/fears/emotions! Sperm production (gametogenesis) is constant in males, and nature is no dummy; one could hypothesize nature finds feedback mechanisms into genetics to compete and gain advantage with other males, even for future generations (?). This should have huge implications if the proper research is continued and these very interesting hypotheses and other´s are seriously questioned.
