The artist did all the things doable to make this dinosaur look ducky,
but when it swam, it might need accomplished so in sand.
What number of readers of science information have a look at the photographs as a substitute of the info? Right here once more is one other catchy artist rendition that misleads the attention as a substitute of informing the thoughts. That is how evolutionary dogma advances: one visualization fallacy at a time.
The Non-Duck Duck
Newly found dinosaur has a streamlined physique like a diving hen (New Scientist, 1 Dec 2022). Reporter Corryn Wetzel posted a big picture of Yusik Choi’s rendition of a creature from bones that’s virtually as excessive because the case within the cartoon above. For one factor, the fossil was present in Mongolia in 2008, removed from water. But Choi portrays it swimming on its breast like a duck, paddling with its hind ft, and sporting a coat of feathers.
A brand new species of dinosaur is the primary discovered to have a streamlined physique like diving birds however not belong to the feathered class of dinosaurs that modern-day birds developed from. This suggests that streamlined our bodies developed independently in several lineages of theropods, a bunch of hollow-boned dinosaurs that walked on two legs and primarily ate meat, together with Tyrannosaurus and Velociraptor.
The toothy snout was made as beak-like as doable. And but all of the stories are calling the creature a dinosaur. The discoverers gave it the identify Natovenator polydontus, “swimming hunter with many enamel.” And but there isn’t a proof it did swim. It had a “smooth physique” and “goose-like neck,” however that’s it. Many of the interpretation is suggestion. With none proof of abdomen contents, they “posit that it ate fish and bugs.”
Mongolian fossil is first recognized species of streamlined non-avian theropod dinosaur to stroll on two legs (Phys.org, 2 Dec 2022). Bob Yirka additionally reproduced the artist rendition on the high of his write-up, and proceeded to birdify this wingless dinosaur as a lot as doable.
The researchers additionally famous that its ribs pointed towards its tail, one other frequent function of waterbirds. However it was not avian—there was no signal of wings. The researchers additionally famous that the general form of the skeleton prompt very strongly that it didn’t use its forelimbs for strolling, probably giving it a penguin-like gait.
New toothy diving dinosaur found ( by Nature Publishing Group through Phys.org, 2 Dec 2022). This press launch printed by Phys.org solely reveals the bones, not the art work. Discover that similarity doesn’t show this creature, no matter it regarded like, was a swimmer and diver.
A brand new species of non-avian dinosaur with a streamlined physique just like these of contemporary diving birds, resembling penguins and auks, is described in a examine revealed in Communications Biology. The findings symbolize the first case of a non-avian theropod—a kind of carnivorous dinosaur that walked on two legs—to have a streamlined physique.
Evolutionary paleontologists, satisfied that birds are dinosaurs, use the time period “non-avian” dinosaur or theropod to seek advice from the lineage that did not evolve into birds. So why cowl it with feathers and make it swim like a duck?
Noodle-necked swimming dinosaur might have been a diving predator like a penguin (Stay Science, 1 Dec 2022). Mindy Waisberger included extra of the art work, exhibiting a second particular person diving deep below the water like a penguin. Like all the opposite gullible reporters, Mindy appeals to the ability of evolution to work miracles.
Ever since the primary vertebrates crawled out of the oceans to dwell on land, “many alternative teams have secondarily tailored to aquatic environments,” the scientists wrote within the examine. Whales, for instance, developed from four-legged terrestrial mammals earlier than adapting to dwell completely within the oceans. Amongst dinosaurs, solely birds and a few of their extinct ancestors developed aquatic or semi-aquatic types.
A non-avian dinosaur with a streamlined physique reveals potential variations for swimming (Lee et al., Nature Communications Biology, 1 Dec 2022). That is the scientific paper. The investigators clearly imagine the fossil represented a swimming dinosaur, however let’s study the precise proof to see how ducky this creature was.
- Any wings? No.
- Any feathers? No.
- Any webbed ft? No.
The physique form solely “suggests” that this creature was something like what the artist depicted. The drive of suggestion is powerful within the imaginations of those evolutionists.
The brand new specimen features a well-preserved skeleton with a number of articulated dorsal ribs which might be posterolaterally oriented to streamline the physique as in diving birds. Moreover, the extensively arched proximal rib shafts replicate a dorsoventrally compressed ribcage like aquatic reptiles. Its physique form suggests that Natovenator was a doubtlessly succesful swimming predator, and the streamlined physique developed independently in separate lineages of theropod dinosaurs.
And so “convergent evolution” involves the rescue once more.
The streamlined physique of the Natovenator additionally displays the excessive variety of physique shapes amongst non-avian dinosaurs and exemplifies convergent evolution with diving birds.
Two feedback have been made by others not a part of the crew. Certainly one of them famous that the genus Homo additionally has a dorsally compressed ribcage. The opposite requested, “This taxon was discovered buried in desert sands. The place is the precise water for the authors’ speculation?” He additionally famous associated taxa that have been desert creatures.
We’ve seen this sort of artwork manipulation earlier than. Keep in mind the platypus-duck-dinosaur 5 years in the past? It was additionally described years after it had supposedly been present in Mongolia. We noticed a great deal of interpretation happening in that case, and the evolutionists waved their magic wand of “convergent evolution” then, too. What’s it with these Mongolian fossils? Is there a racket happening?
The evolutionists say this was a “non-avian dinosaur” due to the strata and site through which it was discovered and due to a few of its skeletal traits. However non-swimmers typically have compressed ribs, and a few animals with lengthy necks weren’t geese (sauropods, giraffes). Many of the traits these evolutionists are saying “recommend” a diving dinosaur could possibly be in any other case interpreted.
A talented artist might in all probability have made this new creature appear like a platypus or a duck-billed Homo in that case inclined, full with imaginary feathers and webbed ft.
We don’t know what this creature regarded like on the skin, as a result of all we have now are bones. No scientist witnessed its life-style and habits. Maybe it did spend a while in water, however plenty of animals do this.
If the Darwin Celebration was not a totalitarian dictatorship, there could be some onerous questions being requested. Evolutionists must quit their magic wands and thought bubbles. They must do rigorous evaluation and stop interesting to the ability of suggestion.
