New Darwinian Water to Land Transition Story: Big Eyes Did It

Science Daily calls it a provocative study, and it is.

Darwinian tales tend to be goal-oriented or teleological.

Why do we have four limbs? an evolutionist might ask. The answer: because we have a belly.

This brings us to the new water-to-land transition story:

A new study suggests it was the power of the eyes and not the limbs that first led our aquatic ancestors to make the leap from water to land. The researchers discovered that eyes nearly tripled in size before -- not after -- the water-to-land transition. Crocodile-like animals saw easy meals on land and then evolved limbs that enabled them to get there, the researchers argue.”

So, marine animals were able to direct their evolution to get “easy meals”.

This is exactly what biologist Aldemaro Romero warned researchers of in an essay he wrote in 2016: He pointed out that they should not expect to see predestination or preadaptation in biology, as evolution had no plan or purpose.

In other words, the blind watchmaker can’t see.

However, everything in us and the animal kingdom looks designed and the most logical explanation is that it is designed.
