"report the draft genome sequence of the sea sponge"Now the evolutionist will say, "See, we use the same proteins; therefore we have a common ancestor!"
"All living animals are descended from the common ancestor of sponges and humans, which lived more than 600 million years ago"
"essentially all the genomic innovations that we deem necessary for intricate modern animal life have their origins much further back in time that anyone anticipated"
However, there is a much more subtle (and damaging) point.
If the earliest life forms have all the complexity - then deep time (the billion year hammer) buys you nothing. Later forms use multiples of these genes, often with slight modifications.
