Why did fish move onto land?

And since it takes generations upon generations to evolve like that, it can be difficult to track. This is why this study can be a very unique opportunity. But one reason why, if predation were the primary driver for the initial transition, that we aren't seeing it much is because it isn't safe on land for everything, anymore. They mention that this island provides that sanctuary, but when the transition first occurred there were no land predators, because there were no creatures on the land. The predators, though, evolved to follow their prey, and so other evolutionary developments had to occur.

Obviously it's not something that will happen in a matter of a 20 year case study. Realistically, every living organism is undergoing evolution; it's just not change we recognize as such. Deer are currently evolving to withstand vehicular impact, unfortunately for them it's at a slower rate than the speed of a sedan.
