Can you breed broccoli with cabbages?
Yes. That's how you produce
Broccolini.
No. It's incomplete enough to not have a perfect record, but, again, there are PLENTY of obviously transistory fossils if you look.
Species not changing.
Fundamentally, if they change, they will eventually drift far enough to have incompatible gametes and thus become a different species.
Good news then, science has overwhelmingly proven that species never change. A chihuahua is still fertile with a wolf if you get the mechanical aspects out of the way, and that's a massive number of generations and thousands of years to play with their genes. Somehow, all we got out of it was funny-shaped dogs, never any other species, and they always remain the same species, according to their kind as the Bible calls it.
Multiple experiments have shown that speciation never occurs. One of the interesting brick walls evolution keeps ramming its head into is the
Law of Recurrent Variation. Decade after decade of mutation experiments showed that a species has only a limited number of variations possible, as they continued to produce mutants, somehow the
same mutants kept arising from different strains and experiments and no new species could ever be created.
A century of
Fruit Fly Mutation experiments proved as well that evolution simply wasn't happening. Millions of generations of fruit flies have been carefully bred and mutation encouraged by every possible means, equivalent to several million years of human evolution. They evolved into... the same damn fruit flies. A fruit fly could be pushed to certain limits within its genome (They cataloged about 3000 variations), and then you produced nonviable flies, not a new species. But soon the law of recurrent variation raised its ugly head and they found themselves breeding identical mutants from totally different strains. Even worse, a second recurrent problem with evolution came to the fore: The genome repaired itself over time, and attempts at breeding the mutant flies began to produce the original strain as the mutations worked their way out of the system.
Even an experiment to try to
Breed New Bacteria covering 20 years and 40,000 generations could not produce a new bacterium, only variants of the already-existing species they started with.
“After observing mutations in fruit flies for many years, Goldschmidt fell into despair. The changes, he lamented, were so hopelessly micro that if a thousand mutations were combined in one specimen, there would still be no new species” -Darwin Retried, page 22
Needless to say, the media and establishment have never been eager to trumpet these results and it's as hard to find mainstream media admitting to proof that speciation occurred as it is proof that Trump won the election in 2020.
