Evolutionists want to claim that they are "living fossils". You know, those things that have not changed much in the alleged "millions of years" from what we see now, and the impressions they made in the fossil record. And yet, they contradict themselves. Darwin's Cheerleaders are carping that the sturgeon does not cooperate with the expected rate of change. Nor do they change enough. But they "evolve" too fast. (Note the bait-and-switch on the word "evolution", which is grossly misapplied.)
There is speciation (expected in the creationist models), but not a shred of evidence of molecules-to-man evolution; you must remember this, a fish is still a fish. A sturgeon is still a sturgeon. They did not care about the evolutionary presuppositions that they are wrecking.
Sturgeon, thought to exist in only around 29 species worldwide, have long been considered living fossils. But now a study published in Nature Communications has dubbed them winners in the race for rapid evolution in defiance of accepted evolutionary principles.
Molecules-to-man evolution, which has never been observed, is generally assumed to be a process requiring a series of changes over millions of years. Darwin coined the term “living fossil” to describe living organisms that have remained unchanged for millions of years. But rapidly appearing variations in an organism, such as those that may ultimately produce new species, are often cited as examples of rapid, observable evolution.
Within this framework, the authors of “Rates of speciation and morphological evolution are correlated across the largest vertebrate radiation” point out:Perhaps learning the truth is giving you a haddock. Nevertheless, you should reel in the rest of "Sizeable Sturgeons Set Evolutionary Speed Records?"
