Nature, Nurture, And Human Diversity

I learned that fraternal twins are not completely the same, they develop from two separate eggs. They can look the same though, but not usually.

I learned that separated identical twins growing up in different environments can still psychologically be identical. The two Jims had the same names and same traits right down to the name of their dogs. That is just weird.

I learned that heritability of certain traits can be in siblings, like Venus and Serena Williams. They are both very could at tennis, but, on the other hand, having to very athletic parents doesn't mean that their child will be athletic.

In the video Natural Selection/Evolutionary Psychology I found it interesting that some of our genes have been passed down from our ancestors in the caveman era. The survival instincts are deeply imbedded into our brains, it won't come out until we are in survival mode. I just thought that it was very interesting that some certain genes could be passed that far along.

In the other video, I thought their findings were somewhat true about what we are looking for in the opposite sex. Men are looking more for a home maker and women are looking more for a provider. In our day and age though, it is getting less common because our gender equality. Still, I think that, like the survival skills, it is in our brain to think this way.
