The Historical past Channel presents self-appointed challengers of science who tackle the concept that aliens brought on the extinction of non-avian dinosaurs
Till now, I’ve assiduously prevented Historic Aliens. I had a sense that if I watched the present—which popularizes far-fetched, evidence-free idiocy about how human historical past has been molded by extra-terrestrial guests—my mind would jostle its means out of my cranium and stalk the earth in the hunt for a kinder host. Or, on the very least, watching the present would kill about as many mind cells as a weekend bender in Las Vegas. However then I heard the Historical past Channel’s slurry of pseudoscience had taken on dinosaurs. I steeled myself for the ache and watched the mind-melting insanity unfold.
I’m really glad that my editors don’t enable me to cuss a blue streak on this weblog. In the event that they did, my total evaluate could be little greater than a string of expletives. Given my restrictions, I’ve little selection however to attempt to encapsulate the shiny, documentary-format garbage in a extra coherent and reader-sensitive means.
The episode is what you’d get if you happen to dropped some creationist propaganda, Erich von Däniken’s Chariots of the Gods and inventory footage from Jurassic Battle Membership right into a blender. What outcomes is a slimy and incomprehensible combination of idle hypothesis and outright fabrications which pit the enthusiastic “historic alien theorists,” because the narrator generously calls them, in opposition to “mainstream science.” I’d say “You’ll be able to’t make these items up,” however I’ve a sense that that’s precisely what a lot of the present’s personalities have been doing.
There was a lot unsuitable with the Historic Aliens episode that I might spend all week attempting to counteract each incorrect assertion. This can be a widespread approach amongst cranks and self-appointed challengers of science; it’s referred to as Gish Gallop after younger earth creationist Duane Gish. When giving public displays about evolution and creationism, Gish quickly spouted off a collection of misinterpretations and falsehoods to bury his opponent underneath an avalanche of fictions and distortions. If Gish’s opponent tried to dig themselves out, they’d by no means have the ability to make sufficient progress to free themselves to tackle Gish immediately. Historic Aliens makes use of the identical tactic—the fictions come quick and livid.

Whereas the primary level of the episode is that aliens exterminated dinosaurs to make means for our species—a sci-fi situation accompanied by some hilarious, mashed-together footage of dinosaurs fleeing from strafing alien craft, maybe a preview of Dinosaurs vs. Aliens the film—the varied historic alien consultants do little greater than assert that such an occasion will need to have occurred. Shock, shock, they supply no precise proof for his or her claims. As an alternative, they borrow proof for fundamentalist Christians, who’re by no means really recognized as such. Creationist Michael Cremo is recognized solely because the writer of Forbidden Archeology, and Willie E. Dye is credited as a biblical archaeologist with none point out of his younger earth creationist views. Historic Aliens producers clearly didn’t care concerning the credentials or experience of the speaking heads they employed—simply as long as somebody mentioned the appropriate issues in entrance of the digicam.
And the creationists didn’t disappoint. About midway via this system, Cremo says, “Some researchers discovered human footprints alongside the footprints of dinosaurs.” The quote is a line out of context from Cremo’s interview, however is performed in a bit claiming that American Museum of Pure Historical past paleontologist Roland T. Chicken discovered human footprints related to dinosaur trackways within the neighborhood of Glen Rose, Texas.
Chicken didn’t discover any such factor. He discovered many dinosaur footprints and trackways—certainly one of which he and his crew partially excavated and anachronistically positioned behind the AMNH’s “Brontosaurus“—however no human tracks. Surprisingly, although, hoaxed human tracks did have a job to play in Chicken’s choice to initially go to the tracksites.
Chicken wasn’t the primary particular person to note the dinosaur tracks, and promoting the sauropod and theropod tracks was a cottage business within the neighborhood of Glen Rose. And some native individuals carved faux human tracks in the identical stone. Chicken really noticed a pair of such forgeries at a buying and selling put up in Gallup, New Mexico, together with dinosaur tracks faraway from the Glen Rose space, shortly earlier than he left to research the location himself.
Chicken wasn’t fooled by the fakes. He noticed them for what they have been, and was far more fascinated about the actual dinosaur tracks imprinted in the identical stone. However some creationists, blinded by dogma, have put their religion behind fakes and even dinosaur tracks that they’ve misinterpreted as being human footprints. When theropod dinosaurs squatted down, for instance, the backs of their decrease legs, the metatarsals, left barely curved depressions within the Cretaceous sediment, and creationists have misconstrued these markings to be the footsteps of historic individuals.
Dye takes up the usual creationist line that people and dinosaurs coexisted and reappears just a little later within the episode to throw his help to a special icon of creationist nonsense—the Ica stones from Peru. These well-known fakes are stones engraved with photos of dinosaurs and people interacting. They have been created by farmer Basilio Uschuya and his spouse, utilizing popular culture depictions of dinosaurs in books as their guides. Regardless of this, each Dye and the Historic Aliens program current the stones as in the event that they have been genuine historic artifacts that document the survival of dinosaurs reminiscent of Triceratops to virtually the current day. Dye says that historic individuals will need to have identified loads about dinosaurs as a result of the stones are engraved so exactly, though we all know that precision got here from Uschuya copying mid-Twentieth century dinosaur artwork so rigorously. Our narrator says that scientists are skeptical concerning the origin of the stones, however nothing extra.
The present affords just a few different terrible gems. Our narrator goes on at size about how carbon-14 courting is unreliable for telling the age of dinosaurs, however paleontologists don’t use carbon-14 to estimate the age of non-avian dinosaurs. Radiocarbon courting solely works for carbon-bearing supplies as much as about 60,000 years previous. As an alternative, paleontologists use completely different radiometric courting strategies to constrain the historical past of non-avian dinosaurs. In uranium-lead courting, for instance, geologists examine the relative abundance of uranium and lead, the aspect uranium decays into, to find out the age of the rock the supplies have been sampled from.
Totally different courting techniques are used for rocks of various ages, and these strategies have put time estimates on when dinosaurs lived. The secret’s discovering layers reminiscent of ash beds that include radioactive supplies and are above or under layers containing dinosaurs. Since dinosaur bones themselves can’t be reliably dated, geochronologists decide the age of the under- or overlying rock to constrain the timeframe for when the dinosaur lived. Historic Aliens, reliant on drained creationist speaking factors, casts aspersions over a course of that the present’s creators clearly don’t perceive.
However my favourite little bit of babble includes the final word destiny of the dinosaurs. The present can’t even maintain its personal story straight. Fringe tv persona Franklin Ruehl makes a case for the trendy or current existence of non-avian dinosaurs by the use of the coelacanth. These archaic lobe-finned fish, which Ruehl rightly factors out have been round lengthy earlier than the primary dinosaurs advanced, have been regarded as extinct earlier than a stay one was hauled up off South Africa in 1938. Since then, a handful of fossil coelacanth finds has bridged the hole between their trendy representatives and those who lived on the finish of the Cretaceous 66 million years in the past. Their surprising reappearance has typically been utilized by cryptozoologists and true-believers of varied stripes to assert that another prehistoric lineage might actually nonetheless be on the market, even when there’s no precise proof to counsel that is so.
As paleontologist Darren Naish has identified a number of instances, although, the coelacanth is a purple herring. In strata from the previous 66 million years or so, no less than, coelacanth fossils are uncommon and exhausting to determine. It’s probably not stunning that their fossil document seems to have petered out. Non-avian dinosaurs, nonetheless, had bones that have been much more diagnostic. The truth is, the decision of prehistoric eras will get higher as we examine slices of time approaching the current. If creatures as giant and distinctive as Triceratops, Stegosaurus, Apatosaurus and Tyrannosaurus actually did thrive for hundreds of thousands of years after the end-Cretaceous asteroid influence, they’d have turned up within the fossil document by now. The proof is obvious—apart from avian dinosaurs, all different dinosaur lineages went extinct about 66 million years in the past.
Shortly after Ruehl makes his proclamation, nonetheless, this system solely forgets what he mentioned. Close to the present’s conclusion, the narrator speculates that aliens manipulated dinosaur DNA to show the imposing creatures into smaller, less-dangerous animals just like the coelacanth. By no means thoughts that coelacanths have been already current on the planet’s oceans greater than 360 million years in the past—greater than 130 million years earlier than the very first dinosaurs advanced. The suggestion is unadulterated bunk (as is that they entire present, actually). After which crazy-haired alien fanatic Giorgio Tsoukalos throws out one other concept. The coelacanth actually did go extinct, he suggests, however was revived by a “direct assure from extraterrestrials” hundreds of thousands of years later. Why? Tsoukalos doesn’t appear to care. And his speaking head friends usually mutter about aliens clearing the best way for our species in some way.
The present can’t appear to determine whether or not aliens exterminated dinosaurs 66 million years in the past or whether or not dinosaurs in some way survived to the trendy period. Which is it? Did aliens clear away dinosaurs in order that we’d stay? Or did some dinosaurs escape extinction in some way? Competing concepts bounce round like ping-pong balls throughout the entire episode. Grandpa Simpson tells extra coherent tales.
There have been just a few actual scientists on this system. Paleontologists Luis Chiappe and Mark Wilson, for instance, make appearances all through the present. I can’t assist however really feel dangerous for them, and ponder whether scientists ought to merely boycott showing on such packages. Whereas I believe it’s worthwhile and important to name out false claims made within the identify of science—reminiscent of clever design and myths of dwelling dinosaurs—packages like Historic Aliens solely abuse scientists. Accountable researchers are sometimes taken out of context to assist arrange unsupported fictions spewed by the alien fan membership. Exhibits like Historic Aliens, MonsterQuest and Discovering Bigfoot apparently have little or no real interest in really speaking about science. Probably the most sensationalist hypothesis will all the time triumph. On these exhibits, scientists simply can’t win.
Historic Aliens is among the most noxious sludge in tv’s bottomless chum bucket. Precise consultants are introduced in to ship sound bites which might be twisted and brought out of context whereas fanatics are given free reign. Fiction is offered as reality, and actual scientific analysis is so grossly misrepresented that I can solely conclude that this system is actively mendacity to viewers. To current the present as a documentary, on a non-fiction community, is a loathsome transfer by the Historical past Channel spinoff. (Technically, Historic Aliens airs on an offshoot of the Historical past Channel referred to as H2.) If the community and the present’s creators need to current Historic Aliens as a lightweight survey of fringe concepts and make it clear that the concepts aren’t meant to be taken significantly, I can’t quarrel with that. However Historic Aliens and exhibits prefer it winnow away at precise scientific understanding by selling absolute dreck. Historic Aliens is worse than dangerous tv. This system exhibits a sheer contempt for science and what we actually find out about nature.
