For the wisdom of this world is foolishness with God. 1 Corinthians 3:19
"Cambrian explosion would have required the origin of many new genes.....
These “homology groups” (HGs) are exactly what they sound like — groups of genes that are similar. A “novel HG” is a group of genes that is found in animals, or particular groups of animals, that do not exist elsewhere. This indicates that these groups of genes were necessary for these animals to exist.
Just how many novel HGs (and genes) are we talking about? The paper is open access, and readers can easily see 1189 HGs are necessary for the origin of Metazoa (multicellular organisms with differentiated tissues), as one moves farther up the animal tree, hundreds if not thousands of additional novel HGs are required:
Of course the paper’s authors assume that these organisms share common ancestors and evolved by Darwinian natural selection — ideas that are challenged by the abrupt appearance of animals in the Cambrian period and by experimental work showing the difficulty of evolving new genes by standard Darwinian mechanisms of random mutation and blind natural selection....in the most devastating manner for Darwinism, namely that the rewiring of the dGRNS was mediated by entirely new genes. The paper’s demonstration that thousands of new genes would have been required during the origin of animals is nothing short of a spectacular." EN&V

- For the origin of Eumetazoa (sponges + Planulozoa + Bilateria), 494 novel HGs are required.
- For the origin of Planulozoa (ctenophores, placozoans, cnidarians + bilaterians), 1201 novel HGs are needed.
- For the origin of Bilateria (animals with two-sided symmetry — a left and a right side), an additional 1580 HGs are required!
We discovered the first animal had an exceptional number of novel genes, four times more than other ancestors. This means the evolution of animals was driven by a burst of new genes not seen in the evolution of their unicellular ancestors.
