I understand that genetics does modify behavior. Believe me, I know this.
I'm just trying to figure out how. What is it about some proteins, the interactions thereof, and the development of the organism that results in a specific behavior (for example, cutting long strips of material, sticking them into the feather on the back, and then building a complex cup nest).
The one thing that I can grasp is the innate behaviors of an organism. As the brain develops, certain circuits are pre-wired evolutionarily, and some of those are these innate behaviors. I can even see how changes to the DNA could end up modifying those pre-wired circuits because of evo-devo principles.
So, is that it? Is that really all there is to it?
If so, then we should be able to determine an innate behavior, find the controlling genes during development and change them to see what happens. Could give us some interesting glimpses into how neural wiring works.
Ignored by those who can't provide evidence for their claims.
