Innovation and Speciation: pre-planning (Evolution)

DAVID: More evidence of living processes antidating need by a billion years:
http://phys.org/news/2014-05-human-heart-billion-year-old-molecular-mechanism.html-QUOTE: "Basically," he says, "when we compare a human and a sea anemone, we're looking at somewhere between 700 million and a billion years' evolutionary separation. Anything that's not fundamentally critical to life as a mobile, multicellular animal is different. And the things we have in common were there in the nervous system of the animal we both evolved from; they were there in the ancestor of virtually all modern animal life other than sponges and comb jellies. Only the fundamental mechanisms are conserved. And this gives us a window into what things we have in common that are extremely important. It tells us a lot about the history of how animals evolved."-Read more at: http://phys.org/news/2014-05-human-heart-billion-year-old-molecular-mechanism.html#jCp-... stuff, but pre-planning is surely going a bit far, as is your "antedating need". The starlet sea anemone, which is still in existence, needs these fundamental mechanisms just as much as we do. May I suggest an alternative to the idea that your god planned the unnecessary sea anemone just so that later on the mechanisms could be used for us all-important humans between 700 million and a billion years later? Could it be that the starlet sea anemone's nervous system is just one of many innovations used and adapted by subsequent organisms to survive or exploit changing environmental conditions? And that all organs go back in the same way to earlier organs, just as all organisms go back to earlier organisms, whether they survived or not in the history of the higgledy-piggledy evolutionary bush? Or do you insist that every innovation leading to speciation (including those that have not survived) was part of your god's plan to produce humans?
