I think the interesting thing is that, in theory, it should be much easier for a modern human's descendants evolve into 'fish' than a modern fish's descendants evolve into a 'human'.

Generally, when animals evolve, they won't lose all their genes used by their previous form. The function of those genes will either be altered, or they simply won't be expressed (the genes are turned off).

In other words, a human should still contain much of the programming to produce a fish, where as a fish would have very little programming to make a human; only things from archaic systems that a human inherited from his fish ancestors.

Do you think a fish could evolve into a human given hundred of thousands of years and the right environmental pressures?
