Weekend Feature: "Intelligent Advanced Versions of Earth's Dinosaurs May Have Evolved Elsewhere in Universe"

New scientific research raises the possibility that advanced versions of T. rex and other dinosaurs — monstrous creatures with the intelligence and cunning of humans — may be the life forms that evolved on other planets in the universe. "We would be better off not meeting them," concludes the study, led by Ronald Breslow, University Professor in the Departments of Chemistry and Biology at Columbia University. 

The study focuses on the century-old mystery of why the building blocks of terrestrial amino acids (which make up proteins), sugars, and the genetic materials DNA and RNA exist mainly in one orientation or shape. 

There are two possible orientations, left and right, which mirror each other in the same way as hands. This is known as "chirality." In order for life to arise, proteins, for instance, must contain only one chiral form of amino acids, left or right. With the exception of a few bacteria, amino acids in all life on Earth have the left-handed orientation. Most sugars have a right-handed orientation. How did that so-called homochirality, the predominance of one chiral form, happen?

Breslow describes evidence supporting the idea that the unusual amino acids carried to a lifeless Earth by meteorites about 4 billion years ago set the pattern for normal amino acids with the L-geometry, the kind in terrestial proteins, and how those could lead to D-sugars of the kind in DNA.

"Of course," Breslow says, "showing that it could have happened this way is not the same as showing that it did. "An implication from this work is that elsewhere in the universe there could be life forms based on D-amino acids and L-sugars. Such life forms could well be advanced versions of dinosaurs, if mammals did not have the good fortune to have the dinosaurs wiped out by an asteroidal collision, as on Earth. We would be better off not meeting them."

maybe some of earth's dinos got intelligent and left the planet a long time ago...
I mean 160 million is enough time to evolve intelligence we did it so far in under 3 million...

Knowing that we can use gravity to magnify an image and that light can bend around a star (and other large objects even dark matter). It should be possible to actually look from Earth’s orbit, at Earth through a Kepler like telescope. My theory is that the sky is filled with so many stars that we should be able to horseshoe our view back to Earth and we should also be able to determine how far back in time we can see depending on the trajectory we use and the distance of the stars we bend on. If the light we see bends around a star by only 1%, then we would only need 360 stars to work with. Even if light only bends 1/10th of a degree, the necessary stars needed would only be 3,600. I think that our own galaxy can provide that. That being said, the farther we train our Kepler like telescope, the farther back in time we should be able to see. Looking through a telescope, 65 million light years means that we would be able to see the Earth as it was 65 million years ago.

Is that even possible to look back in time by hooking around the gravity of stars? I'm a Biologist Jim, not an astrophysicist!

Funny because the Mayans and Babylonians separately reported visitations from winged serpent-like beings that came from the sky and taught them mathematics.

GORN!!

@JohnJohn

Interesting idea, but not theory, it is a hypothesis. {sorry it bugs me when people use those terms wrong). And wouldn't it be only 180 degrees? We the view to come back towards us, 360 would be the same position we started.

We were as welcome in their dinosaur theocracy as Darwin at a creationist convention.

I almost never post in here, but this article deserves to be smacked down hard. The article has nothing to do with dinosaurs on other planets; It's just an overwrought extrapolation made by the author at the end. This blog should be ashamed for giving it play on the internet.

Amoeba people would also have had time to develope intelligence . Or perhaps bacterial intelligentsia . Preon intelligences going viral . What a silly blog this is becoming . I guess reality is becoming to pedestrian . Like doing something real right now in neo or the places that we can actually reach.

I agree with GalacticChimp, this article is rubbish. The chirality of amino acids and sugars have no relationship whatsoever with the intelligence or any phenotype for that matter of organisms derived from said amino acids (as far as we know).
Orientation of amino acids wouldn't change a thing because they are mirror images and if instead of L-amino acids we have D-amino acids, D-sugars will simply be replaced by L-sugars and the polypeptide chain of the proteins will remain unaffected.
Author of this article needs to educate him/herself.

@JohnJohn That's a cool idea, but it wouldn't work as well as you think. The stars you would be bending around would have to all be moving uniformly in relation to earth for long enough to actually see something. That never happens. If an astronomer did calculate exactly where to point his telescope so that for a split second he could see earth as it was 65 million years ago he wouldn't be able to actually see any of the species on earth. It would just be a faint blue speck that just blips up really quick.

Nice concept . i really like the imagination. take a look at my blog too.

I think it would be impossible to know exactly where to look if you were able to bend the light around stars since earth and the sun are orbiting our galactic center and in the process moving up and down in relation to the plane of the galaxy. It would be like looking for a needle in a billion haystacks.Best way to do it is to use a wormhole to bend space to a point 65 million light years away and try to find earth,still impossible I would think.

We had dinosaurs on Earth for millions of years, and not one shred of evidence they were intelligent like humans. There were no evolutionary pressures for advanced intelligence. The pressure was to get bigger and bigger, or smaller and smaller. Any pretense of intelligence is just speculation. No one knows for sure that raptors had intelligence. It's impossible to prove that they even hunted in packs, as it is fashionable to portray in dinosaur documentaries.

In fact, I get the sneaking suspicion that this "research" is a subtle attempt at starting a viral marketing campaign for a movie coming out in the near future featuring "intelligent dinosaur aliens".

If it was 100 million years in the future what evidence do you think you'd find of our civilization. Maybe some fossilized landfills or cemeteries but you'd never find them unless you knew exactly where and how deep to look.

It only took us a few million years to go from sentient primate to space fairing homonid, dinosaurs had 180 million years to play around with. We find groups of injured raptors near large herbivore skeletons so we know they hunted in packs. Some raptors had opposable thumbs and very large brains. All surviving dinosaurs have complex social structures and vocalizations, you could easily compare the intelligence of a crow or a parrot to that of a dog or monkey.

I think that It's absolutely possible one or more species of dinosaur became civilized then either died off or left. It's so far in the past there's just no way to know. We really understand very little when it comes to what happened before we were here.

What happens if we do meet them, it will be aliens vs predators vs humans vs V, and ET, all over.

all I know is that I love that Star Trek Voyager episode called Distant Origin. Totally looks at this theory.

@bob: You would want the 360, and yes you would be back to where you start, well almost. You would be catching the light given off by our planet from about 60 million years ago, so you wouldn't necessarily be seeing back in time, but the residual light from then. Although, as it is later noted by Jason, it would be a blurry ball, thanks to the gravitational distortion. The more it gets bent, the more distortion. Though I do believe, if the right combination was found, we would be able to see more than just a blurry blue ball. And in effect, we could be able to almost see the big bang as well if it was aligned properly.

Who wrote this rubbish? The referenced article published in the Journal of the American Chemical Society was NOT scientific research about advanced dinosaurs on other planets. One comment was made by the author, strictly hyperbole to give readers a laugh at the end.
