Eli5 how genetic memory and instinct works?

315 views

I dont understand how instinct is transferred from parent to the child through genetics. How can a memory or behaviour be stored in genes? For example a snake has the instinct to hiss but how was that transferred from the parent to the child through genes? And how does it go from being just a genetic memory to actually go into the brain of the new animal and make them perform that behaviour?

You’re getting confused. Genetic memories, as depicted in works like Assassin’s Creed, aren’t a real thing.

A snake doesn’t necessarily have the genetic instinct to hiss. But it’s a thing it can do, it’s advantageous for it to do so, and it’s probably seen other snakes doing it. So it hisses.

I mean, think about the noises you make with your mouth. You weren’t born with the ability to speak your native language. You didnt interit it from your parents. You heard others around you speaking it, and picked it up.
