Every animal that is born already knows some basic stuff instinctively. How? I often read that this is genetic. But how is that stored in genes?
In: Biology
Well, the short answer is we don’t fully know yet, because it’s quite complicated. Instinctual behavior is usually the result of many, many different genes working together in harmony to cause a certain action. So there isnt a single gene that is responsible, for example, the instinctual behavior of birds migrating. There will be many different genes acting in concert to cause this: some may start months in advance triggering extra hunger, while others cause these calories to be turned into larger fat stores, hormonal balenced can be changed to increase or decrease feelings of anxiety/fear/boldness/etc, increased sensitivity to climate temperature, and many more.
