Over AtBC, one Timothy Horton, ignorant coward extraordinaire, told me that evolution is a mechanism of evolution. And that giraffes evolved from non-giraffes via evolution! From there the moron moved to "evolution by common descent" as the alleged mechanism that can produce giraffes from non-giraffes.
And yet "evolution by common descent"
can only produce more voles starting with populations of voles! It can only produce more bacteria starting with populations of bacteria!
Not only that, the mechanism of "evolution by common descent" is too vague and as such it is a coward's choice. It definitely isn't science. "Descent with modification" is also useless unless you can specify what gets modified. Merely saying "the genome is what gets modified" just proves that you don't know. Descent with modification gave us the voles. All voles have the same body plan. And yet the genomes have evolved "
60-100 times faster than the average vertebrate in terms of creating different species".
Natural selection was Darwin's choice of an evolutionary mechanism that he alleged to have creative powers. It has FAILed, miserably, in that regard. And that brings us to my point- there isn't an evolutionary mechanism capable of producing eukaryotes starting with populations of bacteria (prokaryotes and archaea). Given single-celled eukaryotes there isn't a mechanism capable of producing metazoans. That list goes on and on.
So how do evos "test" their claims of universal common descent? Phylogenetics, which only looks at similarities. and the alleged divergence, ie range of differences. Similarities that are easily accounted for via a Common Design, and of course convergent evolution. From a Common Design point of view, the differences are due to different requirements of the organisms.
The main problem with phylogenetics is mechanisms dictate patterns. So without a mechanism any alleged evolutionary pattern generated by phylogenetics is bound to be incorrect, or not even wrong. And taking a look at the differences in genes that still produce the same protein will NEVER say anything about the obvious anatomical and physiological DIFFERENCES observed between two species that are alleged to share a common ancestor. Phylogenetics assumes there is a mechanism capable of producing the diversity of life starting from some unknown populations of bacteria. That means it assumes the very thing that requires a scientific explanation. And that is putting the horse before the cart.
