Chapter six was also an interesting chapter, especially with all of the pictures and diagrams, they really help explain what he's talking about in the chapter. This chapter had alot to do with chapter 3 and how embryos develop over time. The part I found most weird was when he talked about the blastocytes and how some of them implant on the rectum or uterus I had never heard of that so I thought that was interesting. I also thinks its interesting how alot of animals whether mammals, reptiles, birds etc. all essentially begin developing in the same manner. I really liked the hox genes picture with the flies and the human figure it explained alot.
Now off to Chapter 7...
