20 Million Year Old Spider Found 413

Posted by ScuttleMonkey from the complete-with-drivers-license-and-birth-certificate dept.
evil agent writes "BBC News is reporting that Paleontologist Dr. David Penny has found a spider, and two droplets of blood, perfectly perserved in amber. He was able to extract the blood and determine its age: 20 million years old. Since it is thought to be the first time that spider blood has been found perserved in amber, it is hoped that DNA could be extracted."

      A really cheesy Sci-Fi Channel Original sci-fi/horror flick at that. Give 'em about six months and I'm sure they'll already be a week into filming Frankenspider III - After the Armageddon. Has anyone seen the crap they've been funding these last few years?

        I just read an article about these new "B" movies on Sci-Fi network. Aparrently they have around 30 in the can for the year and they do very well (relatively). Each one has a very low budget (I think I read 1 million), and given that SciFi is one of the more popular networks on cable right now, I'm sure they make that money back quite handily and then some.

        Personally, I think it's great that they're bringing back the cheesy sci-fi movies. That means we might have a MST4K one day.

          No we can't. Carbon dating tries to determine how long something has been dead from the ratio of radioactive versus stable carbon in its tissues; it is assumed that as long as the thing lived, it exchanged carbon freely with the surroundings (getting into its tissues tiny amounts of radioactive carbon produced in the upper atmosphere among the stable isotope), and when it died, this exchange stopped, leading to the radioactive isotope being depleted from those its tissues through radioactive decay.

          In any case, Wikipedia claims that carbon dating can only be used to measure times some 60 000 years back, so this seems rather irrelevant for the discussion at hand.

        Dr David Penney didn't use carbon dating. Carbon dating [wikipedia.org] only works to roughly 60,000 years ago. Beyond that, the radioactivity of the little C-14 that remains falls can't be told from background radiation.

        Well please let me know what science you've discovered that conflicts with all known, tested, and proven nuclear theory. Regardless, carbon dating is only good for up until about 60,000 years old. After that many other methods can be used, most of those methods are proven and extremely accurate. Please also keep in mind that scientists rarely, if ever, only use one method of dating something. By using two or more completely unrelated methods to date a specimen you can get its age to within extremely small margins of error.

        Carbon dating, and similar methods, tend to often be most useful for mummies and humans or recent dead animals. Methods like those can't be used on dinosaur bones because most of the time the bone has been replaced with a different material (one example would be in southern south america, some major finds have been found but the bones were hard to move because they were nearly pure iron and bigger than a man.) You should read up on the science, its a very mature and well understood thing. The media does shitty research and doesn't check any facts that various religious groups tell them. Learn for yourself, you can probably take a class in it at your local college.

        The intelligent design folk tend to be ignorant and ignoring facts. They can't accept the truth because they want more to their life, they want to believe that God designed people after himself (which in my eyes is a pretty conceited view, and also an insult to God considering how crappy and fragile we are designed, not to mention the numerous unused organs... I guess God just wanted to weigh us down.) I am a religious man, but some people associate evolution with meaning there is no heaven (not necessarily a true relation) and can't go through life not thinking that there is some higher meaning for them living. Its really all a case about people not being as important as they want to be. Its always been that way (hell, for centuries we claimed we were the center of the friggin Universe) and some people just need to wake up and accept the truth.

        The baseline concentration of carbon 14 is from a 1950 measurement - C14 is atmospheric nitrogen bombarded by naturally occurring radiation, the C14 is incorporated metabolically into living organisms - but only as long as you're alive and respiring.

        As to accuracy, there are calibration curves for it against other known counters - tree rings etc.

        As to precision, there was also a recalculation of the half-life - but they were only off by a few percent.

        They're not off by an integral factor, they're not off by an order of magnitude. But after ten or so half-lifes, the differences become too small to be practically useful.

          Even sub-optimal biological systems can not-change for a long time under these and other conditions;

          - adaptions prevent or correct mutations
          - long lifespan
          - many breeding partners over a wide area
          - no predators (like sharks)
          - stable environment in the relevant parts (sharks that I know of do not specialize in foods for example)
          - large population
