Okay, so it seems that everyone is lavishing Mr. Shubin's story with praise in his enticing story. But to me, it leaves me confused. I understand that the flesh and the bones--they all change. But what about the organs? How to fish become mammals? Do organs also start to adapt to certain situations? Will forcing fish to "breathe" on land give the fish lungs capable of breathing air? So that probably means that we, as humans, can go back to living in water--if forced to.
Personally, I try to stay away from evolution. The fact that we even evolved makes me wonder what we started as, and what we're going to become. Shubin shows us the linchpin that connects fish and mammals, and all I can say is that his argument--about us being related to fishes--is quite logical. But I'd really want to hear what his "supporting details" are.
...Apart from all that, though, I am really intrigued by his mentioning of the always-changing landscapes, and how mountains become valleys, etc. Personally, I did not know anything about changing terrains, besides lakes turning into deserts from the movie Holes.
