To go along with DNA for dummies? or for the FBI?
From Wikipedia: DNA, “However, there is no direct evidence of ancient genetic systems, as recovery of DNA from most fossils is impossible. This is because DNA will survive in the environment for less than one million years and slowly degrades into short fragments in solution.” I think that’s the understatement of the year!
Check this out: if you want to extract DNA from a specimen to study, here’s how to do it, “Using ice-cold water and ice-cold alcohol will increase your yield of DNA. The cold water protects the DNA by slowing down enzymes that can break it apart.” from Learn Genetics U. of Utah. There’s no way students were taking anything close to a million years to try to extract their DNA samples!
