It hardly falsifies evolution, it just shows how poor the fossil record is from 500 million years ago.
Classic, evolution cites the fossil evidence as one proof of evolution and when there's a dire absence of such evidence you claim the evidence would exist but was inexplicably not preserved.
Tell me what evidence can you present that shows the Cambrian fauna did evolve? None, without the fossils you have no evidence for the claim and you really can't go around demeaning those who point this out.
How do you know these untold millions of generations of evolving animal phylae actually ever existed at all?
There's
nothing wrong with the fossil evidence, we have pre-Cambrian fossils of delicate jellyfish even amoeba, perfectly preserved, so why do you claim the missing fossils are not evidence of absence?
The situation is very clear, the fossil record
shows that the Cambrian fauna (40+ phylae) arose almost spontaneously without any long drawn out evolutionary process, that's the most rational interpretation of the fossil record.
If the Cambrian fauna did not evolve we'd expect to see exactly what we do see in the fossil record!
The Cambrian fossils and the accompanying absence of credible precursors is a pattern repeated all over the earth, it seems to be universal, not just a local absence.
It is equally reasonable to say it proves evolution since suddenly (only a geologist could call tens of millions of years 'suddenly') new species appeared. There is zero evidence of new species appearing by any other process.
It is geologists and paleontologists who named this an "explosion" it is they who describe it as "sudden" I am just using terms that they use!
As for the "process" that gave rise to these animals, a true scientific thinker doesn't teach and promulgate a fairy story just because they don't know what actually happened, instead they say "I don't know" something the evolution cultists cannot bring themselves to admit.
They are as fanatically religious as the theological fundamentalists we see around us, insisting they know when they don't, insisting conjecture is fact, attacking anyone who dares to question their dogma, they are no better intellectually than those who imprisoned Galileo, dogma is dogma.
