A Surprise for Evolution in Giant Tree of Life

• arclein

This controversial proposal stems from efforts by Hedges and collaborators to build the world's most comprehensive tree of life ?" a chart plotting the connections among 50,000 species of Earth's vast menagerie. Their analysis suggests that speciation is essentially random. No matter what the life form ?" plant or animal, insect or mammal ?" it takes about 2 million years for a new species to form. Random genetic events, not natural selection, play the main role in speciation.

Evolution continues to fail in many points, but two of them are major. These point revolve around the word "random." "Random" does not mean "spontaneous." There is nothing that we know of in the universe that rises spontaneously, all by itself, without one or more causes. Sometimes we know the cause, and sometimes we don't. True spontaneity doesn't even make sense in physics. (Continued below.)

(Continued from above.) This leaves us with the understanding of what "random" really means. "Random" simply means that we don't know the cause. As far as we know, the cause could have been this, or it could have been that. Since we don't know, why don't we say it that way. We don't know that the tree of life chart is anywhere near correct or not. This means that evolution is as it always has been >>> something we don't know anything at all about.
