You do not seem to understand that many more fossils have been found since the time that PE was proposed. It is still a well accepted hypothesis, that there are periods of very rapid evolution, and it is now supported by transitional fossils.
Of course part of the problem is the denial of science by creationists. They cannot afford to understand the concept of scientific evidence, nor can they afford to understand the concept of transitional species either.
Of course when transitional fossils are provided then creationists demand to see transitionals between the transitionals.
That’s bogus.
Transitional fossils are still missing in all the important areas.
And common sense knows that there can’t be short periods of intense macro evolution, to the point of creating new body plans.
Wildlife biologists who work with endangered species- the epitome of isolated populations- confirm that isolated populations lose genetic diversity - thus the facts are diametrically opposed to the PE hypothesis.
And the above came from no creationis
But PE is a good example of the fact that evolutionists are willing to accept any half-baked theory tif it promotes ToE.
You might want to brush up on your research, because none of that it correct.
Hint, the appearance of "complex" eyes pre-date the Cambrian.
Second hint, squid didn't exist in the Cambrian - some cephalopod ancestor species can be traced to the late Cambrian.
Spriggina, Marywadea and Kimberella are annoyed at you right now.
The squid is one of many soft bodied creatures that appear suddenly and with a complex human-type eye, with not one transitional form eye predating it.
I’ve seen the research on what the strata below the Cambrian contains, and it contains nothing that is needed to prove phyletic gradualism.
The trilobite also has very complex eyes of a completely different type from the squid eye, and there is not one transitional eye found on any creatures below the Cambrian.
It’s called the Cambrian explosion and called life’s Big Bang, for a reason.
Vertebrates appear suddenly with no transitionals in lower strata, along with complex eyes.
It’s understood that evolutionists have to live in denial and desperately spin the facts, when anything endangers their precious ToE.
