Convergence, Natural Selection, 'Survival of the Fittest'

An example from "Improbable Densinites" for convergent evolution is sea snakes and beaked sea snakes. These snakes are in different parts of the world ranging from Southwest Asia to Australia. It was discovered that Australian sea snakes and the beaked sea snakes are more related to each other just like the Asian sea snakes and beaked sea snakes are to each other. Convergent Evolution is when distance-related organisms develop similar traits to one another to survive in similar environments. These snakes are examples of convergence evolution because these two organisms are from similar environments and share similar features. In the way of natural selection the two organisms started out as the same however one evolve a bit more and had to survive in a similar environment with some changes. One could have been eaten more than the other so one had to go to a different part of the ocean to be able to survive.
