Fossil Non-Embryos Quench Cambrian Explosion Fuse
Alleged fossil animal embryos in Precambrian rock in China are not. Last year (06/18/2006) and before, researchers found what looked like cleaved embryos in the strata under the Cambrian “explosion” layers. Now, a paper in Nature reclassifies them as giant bacteria, not embryos.1
Some evolutionists had hoped the discovery of animal embryos would soften the explosion by pushing the origin of symmetrical body plans further back in time. In a News and Views article in the same issue of Nature,2 Philip C. J. Donoghue (U of Bristol) termed this an “embryonic identity crisis” that deflates those hopes. “The oldest known animal fossils, identified as eggs and embryos, had been expected to reveal secrets from a period of great evolutionary change,” he said. “Will the latest theory about the fossils’ origins confound these hopes?” Apparently so; he ended by admitting that evolutionists still have “overarching questions” about the timing and embryological basis of animal origins. Finding that these structures are something less than embryos means the evolutionists are back at square one; “like all other theories about Precambrian animals, the classification of these fossils is far from resolved, even at the kingdom level.”

Evolutionists have been on their own one-yard line since they took possession of the ball and got the referee to disqualify the other team. Even with their overwhelming advantage, they have been moving one yard forward, one yard back for 146 years. The crowds are getting restless.
