Well , it attend like we may never have our own Jurassic Park . Scientists at the University of Manchester failed to pull up DNA samples from dirt ball immobilize in 10,600 year - sometime amber , go them to conclude that the chances of educe entire deoxyribonucleic acid from samples millions of years older is likely impossible .
For those survive in a palaeolithic - era cave , the dinosaurs in Spielberg ’s 1993 classic , Jurassic Park , were spawn from DNA samples taken from amber - trap ancient insects binge with dinosaur blood . It ’s a fascinating melodic theme , but unfortunately — or fortunately , reckon on your opinion of dinosaurs — it ’s probably not gon na happen .
In the newfangled study , David Penney and confrere essay to press out deoxyribonucleic acid from insects in subfossilized copal , the hardened rosin from trees that ’s a precursor toamber . But they could n’t do it ; they were n’t capable to detect an ancient desoxyribonucleic acid in samples ranging in old age from 60 to 10,10,600 years older .

The researchers used stingless bee encased in copal to judge and detect DNA sequences from the insects .
Interestingly , in the youngest specimen , they were able to match some isolated sequences of just over 500 nucleotides — the molecular building blocking of desoxyribonucleic acid . But they were abortive in matching the isolated succession to genes from mod stingless bees .
“ Intuitively , one might imagine that the everlasting and rapid engulfment in rosin , ensue in almost instant dying , might promote the saving of DNA in a rosin entombed insect , but this appear not to be the case,”notedPenney to The Telegraph , “ So , unfortunately , the Jurassic Park scenario must stay on in the realms of fiction . ”
This is all a flake of a arguable point , by the manner . Late last year scientists were able-bodied topeg the half - life of deoxyribonucleic acid at 521 years , intend that , under idealistic conditions , every last piece of DNA would be become by 6.8 million years , and there would only be enough to be readable at around 1.5 million years . The dinos went fossil about 65 million year ago .
