Can We Get DNA From Fossils?

  • Published: 03 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.

                              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?

                                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

                                  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

                                              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.

                                                                                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.
