Evolution Ought To Be Rewritten

By Dr. Tas Walker, BiblicalGeology Blog, September 12, 2012:

Paleobiologist Simon Conway Morris, of Burgess Shale fame, says that examination of the fossil evidence demands a radical rewriting of evolution. Why so? In an interview with the University of Cambridge’s alumni magazine (Issue 65, Lent 2012, pp. 32–35) Conway Morris says it’s because of “convergence”.

That’s the tendency of very different organisms to evolve similar solutions to biological problems. He wrote of this phenomenon extensively in his 2003 book Life’s Solution.

Conway Morris illustrates with the “camera eye”—“the kind of eye which you are using to read this feature.” That eye comprises a lens suspended between two fluid-filled chambers.

Conway Morris points to the octopus, which:

“has a camera eye which is remarkably similar to our own. … And yet we know that the octopus belongs to an invertebrate group called the cephalopod molluscs, evolutionarily very distant indeed from the chordates to which we belong.

“The common ancient ancestor of molluscs and chordates could not possibly have possessed a camera eye, so quite clearly they have evolved independently. The solution has been arrived at by completely different routes.”

Or, as the interview explained, “evolution has converged on a solution.” (…)
