Ch. 2: Getting a Grip

As I began reading this chapter, what I found interesting was the introduction. Shubin was explaining about his experience at the medical school anatomy lab and I thought to myself, 'How does this relate to anything?' Soon enough, I found out his intention in trying to relate his emotional discovery on the human hands to his discovery in the ancient fossil hands. And something that I though was really interesting was his finding of the half fin and half limb fossil. He explained how it was difficult to find the transitional fossil between the sea creature and the land creature and I thought it would be impossible. However, he did find that fossil and in page thirty-nine, he demonstrates his discovery with the picture. I was surprised to see that the Tiktaalik actually had a wrist similar to a human's.

As Shubin went on, his explanation of ancient creatures having the ability to do push-ups was pretty unique. Through the picture in page forty, he thoroughly explained Tiktaalik's hand/wrist structure, being able to glide across the bottom of the ocean. Although I'm still a bit skeptical of the whole evolution from fish to human, I find many of Shubin's explanations pretty interesting and am looking forward to more of them.
