Instinctual Behavior Vs Intelligent Decisions

Either it is not transferred or it is learned by the next generation.If there is variety in the next generation regarding the ability to learn this skill, then we might find that those with the brain structures that make learning the skill easier and quicker (as a result of their particular genome) will more successfully reproduce meaning the generation that follows them will inherit those same brain structures leading to an increase in frequency of quick learners. For any specific crow, this is true. And crows don't get a choice in the matter, it is not a case of being stupid. Evolution is a population wide phenomenon, though. So in the population there is likely to be variation in learning speed. If there are suitable selection pressures we might find the learning speed approaches zero over time. If that happens what was once a learned skill is now instinctual.

Yes. Through the genes. I don't follow the question. I'm going to answer: When the brain develops. In so much as behaviour has an impact on the destiny of a population. Yes. Maybe, thought there are certain brain structures that I believe that are unique to humans. No.

My limited understanding of genetics would suggest that the idea that there is a 'gene for x behaviour' or a 'gene for y trait' is erroneous thinking, possibly fueled by journalistic reporting of genetic studies which merely indicate that certain genes may be involved in some way with said traits.But I would say that I think studies in mice and other similar animals have shown that instinctive traits such as 'aggression' have a genetic component, but I don't know the details. I guess you could look them up with a bit of searching around if you are genuinely interested.I do seem to remember that when scientists domesticated foxes, making them less aggressive this had an impact to their coat colour because coat colour was on the same developmental pathway as adrenaline or something along those lines. This was thought to be genetic.I'd hunt around for something more specific, but since it isn't really the topic of this thread, I don't feel compelled to throw this thread in an off topic direction for you.Edited by Modulous, : No reason given.

Right. So why ask

Had ever been found a specific gene related to a specific instinct or part of it?

If you already knew the answer? But the way intelligence is inherited is via the genes, that was the question I was answering. The way it develops is through interaction with the environment.
