"Conservative Dogma"???
The Burgess Shale?
The Chengjiang fauna???
Really?
Nobody is saying "Darwin got it wrong" because we're finding fairly impressive fossils from the Cambrian.
Yes, the Cambrian explosion is interesting. It doesnt' disprove evolution. It certainly doesn't make the Bible true or prove there's an invisible sky pixie.
Actually, real scientists are saying just that:
Darwin got it totally wrong.
4. Not only does the evidence of the Burgess Shale, and of the Chengjiang deposits, run counter to Darwin's views, but it is in the Chinese Communist party paper, "The People's Daily," that we find Chinese paleontologists stating that these discoveries challenge a Darwinian view of the history of life.
a." Marine biologist Paul Chien at the University of San Francisco was one scientist who followed the news closely. What drew his attention were a couple of articles that were published in the People's daily, the official newspaper from the Communist Party in China. The article stated the
Chinese fossils drew the attention of scientists worldwide and this fossil find actually challenges the theory of Darwin's evolution.
b. ... December 4, 1995,
Time Magazine published a cover story entitled Evolution's Big Bang. The story included great detail about the Chinese fossils. Since 1996 Paul Chien has made several trips to conduct his own investigation in China of the fossil site.... the Cambrian explosion absolutely challenges the idea of the traditional view of evolution. The problem is that all of the various fossils and animal species found have clearly appeared in a very brief period of time. This is very difficult to explain from the evolutionary point of view.
c.
Paleontologists have determined that the Chinese fossils were older than those excavated in the Burgess Shale in previous years. Yet, anatomically they were often even more complex. "

As you are a novice, let me point out again the significance of "...
anatomically they were often even more complex. "
For Darwin to have been correct....the early fossils had to have been simpler.
In "Origin," Darwin provided his famous tree diagram, which illustrated
his idea of universal common descent, with higher taxa emerging from lower ones via the accumulation of slight variations. "The diagram illustrates the steps by which small differences distinguishing varieties are increased into larger differences distinguishing species.."
Darwin, "On The Origin of Species," p.120.
In short, diversity would precede disparity ( 'disparity' refers to major differences that separate phyla, classes and orders.)
But
the actual pattern in the fossil record contradicts this prediction. In actuality, the fossil record shows representatives of separate phyla appearing first followed by lower-level diversification.
