I learned about fraternal and identical twins in this chapter. I never knew that Mary-Kate and Ashley Olsen were actually fraternal twins. I found this very interesting, along with the differences. Another thing that was interesting were the set of identical twins who were on their way to give each other Christmas presents and ended up colliding with each other on the way there.
One other thing I learned were that fraternal twins actually don't share the same DNA, whereas identical twins have identical DNA make-up. Identical twins are formed from one fertilized egg that splits into two. Fraternal twins are made from two separate fertilized eggs.
The final interesting thing I learned was the nature and nurture issue. I learned how parents influence your life, and how who you live with will influence you in to being the person you are. If your parents drink alcohol a lot, there is a better chance that you will also. If your family is very church oriented, there is a very good chance that you will be also.

I also find the story about the twins crashing into each other very interesting. What are the chances of that ever happening again. I guess sometimes weird things just happen.
