The genetic “proof” for ancient aliens

I have a new, horrible obsession – the History Channel’s show Ancient Aliens.

On Saturday I found myself drinking with a group of my boyfriend Sean’s friends, when one of them announced that we must play an Ancient Aliens drinking game. I had no idea what the show was, but became intrigued when they started discussing the rules of when to take a drink:

  • Whenever someone being interviewed has no relevant credentials like a PhD
  • Whenever someone says the phrase “Some scientists say”
  • Whenever someone says the phrase “ancient astronaut theorists”
  • Whenever an ancient manuscript is displayed
  • Whenever there’s a terrible CGI reenactment
  • Whenever Giorgio starts talking

Me: Who’s Giorgio?
Them: Oh, you’ll know who Giorgio is soon enough.

This is Giorgio, by the way:

…That’s all I’m going to say.

They decided to reduce the list so we would wouldn’t get alcohol poisoning. But I found myself following my own rule of “drink whenever someone says something that blatantly defies logic or is a total non sequitur.” Which meant I was pretty much constantly drinking for an hour and a half. Especially when you’re jumping from pyramids, dragon drawings, Tesla coils, and the Bible all being proof of aliens (just to name a few).

For those of you who’ve never seen the show…I’m not quite sure how to summarize it. The footage looks professionally done since it’s on the History Channel, and some of the shots of the ancient artifacts are cool to see. But if I had to summarize the major theme, it would either be “Brown people never could have done <insert amazing feat here> because they were too lazy and/or stupid, therefore aliens had to help them.” I think my favorite mindblowing moment was when Giorgio explained that:

  • People worship “Gods”
  • But people only believe in things they have evidence for
  • They had written/drawn evidence for these “Gods”
  • Written/drawn evidence is always realistic and never abstract, imaginative, or metaphorical
  • But “Gods” don’t actually exist
  • Therefore they were actually aliens

Oh, Giorgio. How I wish point #2 was true.

Something about the show hooked me in its terribleness. My emotional reaction was actually very similar to the time when I visited the Creation Museum. Yes, I was mad at how they were twisting science, using terrible logic, and spreading blatant lies. But the absurdity of it all was oddly amusing. By the end you find yourself playing along, like you’re watching a fantasy novel… and not something people actually believe.

Also, being heavily inebriated helps.

So Sean and I plowed forward to episode two, since the first two seasons are conveniently available on Netflix. Our “game” was to guess what sort of bizzaro conspiracy theory the show would provide to explain a phenomena they were hyping before the show made the reveal. Sean was a little too excited when he correctly guessed the “Humans and aliens had sex and interbred” plotline. To which I replied, “But they’re an alien. Humans can’t even breed with chimps. Humans would have to actually be aliens seeded here or something for interbreeding to be possible.”

And then that’s exactly what the show said, and I nearly peed my pants laughing.

But the real kicker came when the show brought up the human genome. Sean and I both study genomics and evolution, so we exchanged a wary look. I’ll let you see it for yourself. The clip begins at 7:34 in the first video, and continues until 3:03 in the next.

In case you can’t watch the video or had trouble following that pristine argument, let me summarize:

  • Geneticists discovered the gene HAR1, which is unique to humans and plays a critical role in the development of the human brain.
  • Did it develop through evolution? Francis Crick says human genes couldn’t have evolved because there’s not enough time for DNA to evolve by accident. He said it would be as improbable as a hurricane going through a junkyard making a Boeing 747.
  • Since it couldn’t have evolved, the aliens performed a targeted mutation in HAR1 to make us “human.”
  • We only understand 5% of the genome. If you wanted to record an eternal message that could be decoded by a creature that eventually evolved enough intelligence to decode it, you shouldn’t put it in a monument or text that can be destroyed…put it in the DNA! OMFG THAT’S WHAT JUNK DNA IS! SECRET MESSAGES!

And now, for a quick debunking:

  • HAR1 is present in all mammals and birds, not just humans. But in all non-human species, the sequence is effectively the same, or conserved. The human copy in particular has a number of differences compared to other species, so we consider the human copy of HAR1 divergent. This is not at all the only human gene to be divergent. And all species have uniquely divergent genes – that’s precisely what makes things different species. But no one is arguing that marmosets or fig trees or syphilis are actually aliens with special alien genes inserted into them. Well, maybe people are arguing that. There’s four seasons of this crap, and I’m only on episode 3 of season one. Maybe the syphilis aliens are right after the episode titled Aliens and the Third Reich (I shit you not).
  • Francis Crick has always been a strong supporter of evolution and has spoken passionately about how evolution shaped his scientific investigation. He was one of the Noble laureates who advised US courts bogged down by creationists that “Creation-science’ simply has no place in the public-school science classroom.” He also was an advocate for making Darwin Day a British national holiday. While he was initially doubtful of the origin of the genetic code and wondered if panspermia could be the answer, he later published a retrospective article where he and his colleague “noted that they had been overly pessimistic about the chances of abiogenesis on Earth when they had assumed that some kind of self-replicating protein system was the molecular origin of life.” So, um, no.
  • Francis Crick did not come up with that 747 argument – Fred Hoyle did. That’s why it’s called Hoyle’s fallacy. It’s already debunked a bajillion times by biologists – Dawkins wrote two books about it – so I won’t waste time trouncing it here.
  • Whatever alien thought junk DNA would be a great place for an eternal message is a dumbass. Because junk DNA doesn’t code for a protein or have some sort of regulatory role, it’s what geneticists refer to as “neutrally evolving.” It means it’s at liberty to gather mutations because they don’t have any major effect that would weed them out via natural selection. This is especially true when the show’s premise is that the message was placed there eons ago, and had tons of time to accumulate changes. It also doesn’t explain why chimps share a lot of junk DNA with us, or why a huge proportion of junk DNA are remnants of ancient viruses. I’m sure Giorgio would say that those aliens were trying to throw us off the scent by making it seem like our genomes had evolved through natural processes.
  • They never address the fact that the hypotheses they present throughout the show aren’t even internally consistent. At one point they say all life on earth was put there by aliens, and it evolved naturally. Then they say we ARE the aliens. So what, were the aliens unicellular organisms? How can we interbreed – like they say we do – if we’re that distantly related?! But then they say the proof that we’re aliens is that we look like the aliens…so how about those billions of years of evolution?

In poking around the internet about this show, I discovered that Giorgio had a twitter account, which included this gem:

Lizard people? Total nonsense. Aliens? Of course, duhhhhh.

Oh, History Channel. How the mighty have fallen. I remember when I was little and I’d watch you with my history-buff dad, and learn all sorts of cool things about Egypt and Rome and WWII. But now I watch you to point and laugh.
