Evolution - water to land
Name: marie l todd
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.
