Evolutionary Developmental Biology

Evolutionary developmental biology is very different from other kinds of evolutionary scenarios, and that are important to our discussion. A developmental genes control the activity of many genes. They affect many traits. So if thereis some selective pressure for a trait to change, it's going to most likely not just change the trait under direct selection,. There's a bunch of other shifts that are going to come along for the ride, right? And then that change just remained fixed and the species.
