I promised last year to follow up on more alleged Ediacaran animals. Now is a good moment to come back to this, with a new study having just been published in the journal Nature Communications.
A new fossil worm from the closing days of the Ediacaran is being celebrated as a missing link that demonstrates a gradual Cambrian diversification, not an explosion.
It’s circular: “Because evolution innovates things, it will innovate things if given the opportunity.”
Simple, small, and worldwide in distribution, the placozoa don’t fit any clear evolutionary picture.
The top-down pattern of appearance of animal phyla during the Cambrian explosion represents major conflicting evidence for Darwinian evolution.
