Fish to amphibians

[Ray K]

The next time some questions the likelihood of this evolutionary transition, point out the following real-world examples:

Fish with feet: http://www.derwentriver.tas.gov.au/content/derwent_factfile/spothand.html


Fish with lungs:

Note that one species has primitive lungs, and another requires breathing out of water.

Here is another great example from the fossil record. This actually appears about 30 Myr before the first fossil amphibians.

I hate it when the simple and substantive threads wind their way to the bottom, while prevarications and groundless denials stay on top...

Well, obviously there's a reason for that.
