Neil discov ered that human heads are conduct bid that of a extinct jawless fish which lived millions of years ago. He also says that our hands resemble fish fins in the way they are built, and lastly that parts of our genome look, and also mould like those of worms and bacteria. One burning(prenominal) discovery Shubin made is Tiktaalik, which is a 375 million year previous(a) fossil.

Tiktaalik is a fish that has scales and gills, merely its head is planate like that of a crocodile.

It would use its limbs for support like a tetrapod. Shubin shows how fin structures of fish like Tiktaalik mark the beginning of the evolution into the mammalian duo player and opposable thumb structures in the hands of todays primates. The significance behind Tiktaalik is how it proved to be the missing link which greatly shows the...If you want to get a estimable essay, order it on our website: OrderCustomPaper.com
