One thing I learned from reading this chapter was a better understanding of Identical and Fraternal twins. I learned that although identical twins have the same genes, they might not always have the same number of copies of these genes. Also most identical twins share a placenta, but one of three sets has two placentas. I learned that fratnernal twins develop from seperate fretilized eggs and, although they share a fetal environment, they are just the same as a normal sibling to us.
Another thing I learned is how crucial the things we learn from our parents as a child, are to ou life and brain development. Parents who have poor parenting skills and set bad examples are more likely to have poorly judged, or misbehaved children. Those parents who are dedicated and set good examples for their children are more likely to have children who are well-behaved and successful.

I also found personal space is something that differs in us all greatly.  I learned that Scandinavians, North Americans, and the British prefer to have more personal space than Latin Americans, Arabs, and the French. You would assume that personal space would be a personal preferences, depending how how comfortable or affectionate a person was, but it also depends greatly on the culture they are surrounded with. In France, people traditionally kiss cheeks when they meet. You would never see that happen in America on a normal basis.

The video on sexual attitudes was interesting as well. It shows that there are different ways in choosing who you want to be with. The idea that homosexual men tend to get more sexual relations because they are with another man who want the same thing, is something that I never thought about before. The cultural differences of how we chose, doesn't seem to effect people as much as I thought it would.
