The “sturdlefish” is the offspring of sturgeon and paddlefish—separated by 184 million years’ evolution

They were produced via an accident involving genetic engineering:

The researchers were trying to breed Russian sturgeon in captivity through a process called gynogenesis, a type of asexual reproduction. In gynogenesis, a sperm triggers an egg’s development but fails to fuse to the egg’s nucleus. That means its DNA is not part of the resulting offspring, which develop solely from maternal DNA. The researchers were using American paddlefish sperm for the process, but something unexpected happened. The sperm and egg fused, resulting in offspring with both sturgeon and paddlefish genes.

That should cause the rest of us to think twice about freelance genetic engineering but, sticking to our topic here:

Hundreds of “sturdlefish” are swimming in the tank now. It is not known of those could have fertile offspring. Many other unusual hybrids, like ligers (lion + tiger) or zonkeys (zebra + donkey) or good old mules (horse + donkey) are sterile. The surprise in this case, though, is that the sturgeon and paddlefish are said to be separated by 184 million Darwin Years of evolution – much more distant than the other hybrids. They are also separated by the Atlantic and Pacific oceans. What’s an evolutionist to do with this situation?

David F. Coppedge, “‘Impossible’ Hybrid Suggests Non-Darwinian Change” at Creation-Evolution Headlines


Coppedge reports on various attempts to make this situation coincide with Darwinian dogma, including one at Phys.org: “The researchers also believe the offspring, like most crossbred offspring, are infertile.” Crikey, they’d better hope so. For sure, don’t let them into local waterways. (Oh, wait, they’re planning to breed them in fish farms… )

We are also informed that both fish are “living fossils,” which is supposed to settle the matter.

Read more of Coppedge’s account of the amusing explanations here. Their main strength, as in the YouTube above, is that they uphold Darwinian thinking.

And that’s not the only weird news on tap either: Claim: Microbes that are— individually—100 million years old, come out of hibernation… ScienceDaily: Morono was initially taken aback by the results. “At first I was skeptical, but we found that up to 99.1% of the microbes in sediment deposited 101.5 million years ago were still alive and were ready to eat,” he said.

    This isn’t really good news at all:(

    They can use this to support common to send and then try to replicate the technique and create a humanzee. Which they want to create to prove that we are nothing more than animals

    No, Stalin already tried and failed at creating an army from human-chimp hybrids:

    184 million years of evolution will produce a large number of mutations in these widely separated species. The “sturddlefish” supposedly has a mix of genes from the Russian sturgeon (Acipenser gueldenstaedtii) and the American paddlefish (Polyodon spathula).

    The two species share only their taxonomic order, Acipenseriformes, which includes sturgeons, spoonfishes, and paddlefishes.

    Such a hybrid would be the taxonomic equivalent in the following orders:
    Primates: Orang-orilla (orangutan + gorilla)
    Carnivora: Skonkgoose (skunk + mongoose)
    Ciconiiform: Shoeron (shoebill + heron)

    Since evolution is now considered a fact by scientific consensus, this story must obviously be a hoax!

    However if by some fluke, offspring were produced, they should immediately be destroyed for the sake of science! Otherwise, opponents of evolution will try to get back into schools and raise serious doubts in the minds of impressionable children! 😉

    Not true. Hybrids of (lion + tiger) and (horse + donkey) have produced offspring and in some cases these have also been fertile. This is not surprising if they have a common ancestor and are separated by a few thousands of years of evolution rather than millions.

    Arceng at 3: Thee are even names for the groups of offspring of the errant kitties. For example:


    A liliger is an offspring of a male lion and a female liger (ligress). The world’s first liliger cub was born in Russia, when a female liger (ligress) successfully mated with a male lion. That liliger cub was born in Russia’s Novosibirsk Zoo in September 2012. The birth of the liliger cub was also a major development, because previously it was thought that ligers (A cross between male lion and a female tigress) are sterile and they cannot reproduce. The birth of the liliger has certainly proven that female ligers are fertile and they can easily breed just like normal big cats as well. Furthermore; the birth and the introduction of the liliger cub also included Russia, within the limelight of hybrid animals as well.

    Please note that lions and tigers are species classified in the same genus. Organisms in the same genus are much closer than family, which is much closer than order.

    Querius @ 5. I don’t have references to hand but I recall some cross genera hybrids that also produced fertile offspring. I believe one was a whale dolphin cross (Wholpin).

    It will be interesting to see if the sturdlefish turns out to be fertile.

    Perhaps the real answer is that the taxonomic system is only an approximation to the real relationships between life forms, not a cast in stone scientific fact.

    Aarceng,

    I had to look it up, but the Wholpin cross is at the family (Delphinidae) taxonomic level. However, the taxonomic order would be Artiodactyla, described as even-toed ungulates, which along with cetaceans includes hippos, giraffes, camels, and cattle.

    Perhaps the real answer is that the taxonomic system is only an approximation to the real relationships between life forms, not a cast in stone scientific fact.

    Yes, I think so, too. There seems to be a fair amount of discussion on the roles and reconciliation between classical taxonomy and something called “DNA Barcoding.” From the reading that I’ve been doing, it seems that DNA Barcoding is being used as a tool to be used “alongside” classical taxonomy for the purpose of identifying species. I get the impression that broader applications of DNA Barcoding may have been producing complex and confusing results.
