I have level 2 culture, and I get lots of skills applied to my kids when they are attending lessons. A lot of them are being birthed by skilled villagers, too. I'm not sure what's causing it, but it's happening. One of my kids I think will already be at trainee level once he's old enough to work! I like it, because it makes it so much easier to pick their interests, when you know what their aptitudes are ahead of time.
