Chapter 3: Handy Genes

This chapter was the most exciting, yet, somehow disgusting chapter so far. The experiment on chicken and shark using ZPA and Sonic Hedgehog to create the mirror image of chicken’s wing and shark’s fin. I didn’t quiet understand in written words, but, I finally got it through some grotesque picture. I have just read about creation of mutant. Through the subtitle within the chapter, it got me bit scared of wonder of human’s ability, about how they can manipulate genes of creature and turn into something new. The existence of Sonic Hedgehog in both human and animal signifies the theory of evolution.
