In this chapter, I learned many new things about twins. Ashley and Mark-Kate Olsen aren't idenical twins! Wow! More importantly, I learned that even though identical twins have the same genes, they don't always have the same number of copies of those genes. Identical twins are more similar than fraternal twins when referring to mannerisms and emotions. I find this interesting because my step-dad is a fraternal twin.
I also learned more about gender differences. Men are more likely to desire sex and think about sex. This is all because of gender differences in sexuality. In everyday life, people lable guys as more sexually out there, but now I see the statistics that prove it. This is interesting because just having a certain gender makes you more or less sexual.
Another thing I learned was about mating preferences. Women prefer men who seem mature, dominant, bold, and affluent. Men prefer youthful women who are healthy and fertile with smooth skin and who could be a homemaker. This is interesting because some men do just focus on looks and being taken care of when finding a mate. Yet, some women dig a little deeper to see who is going to be a good father, stick around, and be a good man to them in general.
The Evolutionary Psycholology and Sexual Attitudes video would not play when I tried to watch it.
The Natural Selection and Evolutionary Psychology video was all about genes. Some genes will get passed on, and some genes vanish in all different kinds of species. Every species is good at something because of their genes: birds are good at flying, fish are good at swimming, humans are good at thinking. Humans are survival machines for our genes!
