Can We Get DNA From Fossils?

Loading...
  • Published on: 02 October 2018
  • In 1993, scientists cracked open a piece of amber, took out the body of an ancient weevil, and sampled its DNA. Or, at least, so we thought. It took another few decades of research, and a lot of take-backs, before scientists could figure out how we could truly unlock the genetic secrets of the past.

    How cool now all we have to do is learn the genetic secrets of beto o'dork.

  • Pieter-Bas Hoogsteen

    Could we read DNA of a Purussaurus that lived till 8 million years ago if we really tried? Also could you possibly make a live specimen with it?

  • Alban1 you’re to blame

    11:00 if oil is fossils , should there be dna in it , mixed yeah but still distinguishable , can you get dna out of a decomposed human body

  • Alban1 you’re to blame

    how intriguing, i see signs of a resurrection of earth and its children , you people want rights , what about extinct creatures , don’t this means the chain broke and should be a domino effect, i think you did mistakes and now it’s your turn , maybe you have a chance to reverse this though , according to what i understood is all creation has to be established and secured , or all die , which is just , even according to your own actions , meaning you extinct someone and think it’s OK (because you did it) , than someone else could and should extinct you because it’s OK

    Wasn't there a discovery of soft tissue in dinosaur bones and a human footprint next to a dino footprint. Explain those please.

    Perhaps newer computers and computer algorithms could be developed to advance our ability to sequence more fragmented (i.e., older or less-well-preserved) DNA?

    Thanks! DNA decay is one of the reasons you cant simply put people into long-term hibernation for space travel. You'd actually have to wake them up periodically, to literally let their bodies repair & rejuvenate before putting them back to sleep. Rikki Tikki.

    The research on interbreeding between humans, neanderthals and others has also been plague by contamination problems.It is far from settled science.

    Because dinosaurs pulled out and therefore extinct? Am I right?

    thanks for your video. all humans throughout the entire world are 99.9% the same. and we're about 99.95% the same as we were twenty thousand years ago.

    I wonder if deep learning algorithms could be applied to sequencing incomplete and degraded DNA.

    Have you seen mudfossil University channel? The chap on there has some very interesting DNA findings on fossils

    This is one example where Machine Learning will revolutionize this process. Essentially, the power is in using Feedback Loops.If I can get a piece of A.I. to attempt to sort out the DNA, then give it an accurate DNA simulation on a Quantum Computer so that it can try millions of combinations quickly and see if it can match Phenotypical, and other traits, it can use that to feedback on itself until it makes a Dinosaur that we like.And this is why we are most likely in a Simulation ourselves.

    I've always tried to imagine a re-creation of what it was like in North America when Europeans discovered it. I imagine the Flora and the fauna in the migratory birds in the indigenous species would be quite a scene.

    we could have done those things on the one horned rhino and maybe saved it from extinction.... wasn't that possible?We just had everything we didn't have there.....and most probably we are the reason why it is extinct...
