Another line in the Grand Blueprint
Biologists are realizing that the most common types of fish did most of their early development in rivers and lakes, not in the sea.
Needless to say, this goes along with the earlier realization that fish genes already contain the code for land-walking legs.
At some point a real scientist following good old Ockham will have to conclude:
You can't assume that all life branched out from one location.
That's an arbitrary axiom that needs to be independently proved before you can use it. Otherwise you're running in circles, missing most of the story.
If life randomly started in water, why do the genes of swimming fish contain the code for walking?
If life randomly started on land, why do many land critters have an instinctive 'gait' for water?
The only tenable hypothesis is that life was prepared to live in all sorts of locations, from deep salt water to soil to deep rocks to land surface to fresh water to the clouds.
Where did it begin? Possibly in all of those locales.
