Here are two very interesting updates to my recent articles on alleged Ediacaran animals and the Cambrian Explosion.
Evans et al. (2021) seem to have been well aware of the circular reasoning in their argument.
The new evidence is very ambiguous and totally inconclusive. No far-reaching conclusions should be drawn from such dubious material.
The new fossils stem from a layer in the Nama Group of Namibia, just below an ash bed that could be radiometrically dated to 547.32 ± 0.65 million years.
Günter Bechly explains why the Precambrian fossil Namacalathus fails as a transitional precursor to the Cambrian explosion.
