How did animals evolve from swimming to walking on land?

The standard theory is that they used their fins to move in the mud near the water. Those that were better at this were more successful and survived to propagate and over the generations we got to bigger and better fins and finally legs. One book that tells some of the story is Richard Dawkins, the Selfish Gene. There are lots of other books that will tell this story well.
