SCD's Questions about Sponge Genomes

Restating these inaccurate claims is a waste of time

what inaccurate about this? evolution doesnt predict that primitive creatures were more simple than modern creatures?

Exactly. Evolution can both increase and decrease complexity. There is no arrow of evolution. And it’s already been pointed out that you can have no idea of the genomes of ancient sponges, since you reject phylogenetics.

Nope, it doesn’t.

Nope, it doesn’t.

so the first creature that evolved on earth evolved about 20,000 genes in a single step since evolution doesnt predict a simple creature as a starting point?

You should address your question to someone who wrote that. Please stop polluting our conversation with nonsense.

Nobody ever said anything about a starting point until just now. We were supposedly talking about sponges and animals in general. Very, very far from “the first creature on earth”. Further, you’re always confusing modern sponges with ancient sponges. You can’t know anything about the latter.
