The level of convergence in biology has been found to be amazing in recent decades. Strikingly similar designs run all through the biological world. Such similarities do not bode well for evolution because (i) they are supposed to be independently created by chance events, (ii) often they must have arisen in different initial conditions, (iii) often they are found in different environments and (iv) the design space is large. How can we understand these strikingly similar masterpieces?
Well it really isn’t so difficult after all. You see, if our eye evolved once, then why not twice? Evolution is a story of serendipity, so why not add a bit more? Accepting the evolution of life requires a credulous mind. Once evolution is accepted as fact, all kind of events can be accommodated.
Consider how evolutionist Simon Conway Morris explains convergence at the Map of Life website that documents convergences. Incredibly, for Morris, not only is convergence not a problem for evolution, it actually is yet another proof text. The message from biology’s massive convergence is “First, that evolution is true.” And how do these convergences help support such an amazing conclusion? Morris explains that biology’s very complex structures, such as the bacterial flagellar motor, “evolved independently at least twice.”
In other words, if you think complexity argues against evolution, just look—convergence reveals independent versions, which of course must have evolved. Such independent evolution proves such structures can’t be too complex. So rather than a question mark, convergence actually serves to remove a different question mark: complexity.
I guess the complexity of the eye is even more deceptive given how many times it converged:
The Map of Life documents many more examples of convergence for you to explore, and in fact in the case of the camera-eye alone there is much more to be said. The camera-eye has actually evolved at least seven times, most extraordinarily in a group of jellyfish known as the box-jellies (or cubozoans). Although these jellyfish have a nervous system, they don’t have a brain, and furthermore they belong to a phylum known as cnidarians, widely agreed to be amongst the most primitive of animals.
The more people learn about evolution, the more amazed they are. Religion drives science, and it matters.
