Well this might put a crimp in Steven Spielberg’s plans to make “Jurassic Park IV.” A team of scientists in Australia and New Zealand has concluded that cloning dinosaurs just isn’t possible because DNA would not be viable after millions of years.
In a paper published October 10 in the journal Proceedings of the Royal Society B, the scientists reveal that DNA has a half-life of 521 years. That means that even fossilized or carefully preserved DNA would break down half way in a little over five centuries, then another half every 521 years.
