Sorry I had to do this blog a little late I was planning on putting up my blog on Wednesday but I had a small fever as soon as I came back from Italy, which was Tuesday night. Thankfully this chapter was short otherwise it might have taken longer for me to read since it was hard to concentrate on reading rather than vomiting. Although this chapter was short, it was still very much interesting. And I agree with Pars, this was an easy chapter. The introduction was the most interesting yet! Reading about the development of DNA from Shubin is much more interesting than reading it form a text book plus he describes how to extract DNA from simple things for example: Chicken liver. Then he started talking about scent. Its true smelling does help people a lot, like smelling for rotten foods or drinks or for smoke when there is a fire. I never knew that water mammals used to use their blowholes to smell, I always thought it was to breathe but I guess that’s a result from mutations.
