Of course, I should have said: I’m sure you know this already . . .

In other words, when it comes to skull shape, the changes normal in primates such as gorillas, chimpanzees, and orangutans do not occur or are drastically retarded. If I remember correctly, this is called neoteny by biologists. That is one reason that evolutionary biologists are interested in early development.
