Birds could be theoretically 'de-evolved' back to dinosaurs
Oxford biochemist says dinosaurs and Woolly Mammoths could be brought back to life - but dinosaurs could be trickier.Dr Alison Woollard said it would be theoretically possible to recreate ancient animals, through the DNA of birds.
By identifying and altering certain genes found in the DNA of modern birds, she believes scientists may be able to “design” genomes of the prehistoric creatures.
The theory echoes the plot of Jurassic Park, but comes after a recent attempt to bring back the animals using techniques more faithful to those used in the 1993 film failed.
The Steven Spielberg production saw geneticists recreate dinosaurs using DNA recovered from bloodsucking insects which had been caught in sticky tree sap before it turned to amber.
A mosquito was recently discovered which had the blood of another animal in its stomach dating from dating back 46 million years, not quite the age of dinosaurs, but tantalisingly close.
However, hope vanished when a team at Western Australia’s Murdoch University found that DNA cannot survive for more than 6.3 million years. Most dinosaurs died out about 65 million years ago, in the Cretaceous period.
However Dr Woollard, from Oxford University’s Department of Biochemistry, has suggested the feat could be achieved by “de-evolving” birds.
“We know that birds are the direct descendants of dinosaurs, as proven by an unbroken line of fossils which tracks the evolution of the lineage from creatures such as the velociraptor or T-Rex through to the birds flying around today,” said Dr Woollard.
“The most famous of these is the Archaeopteryx, a fossil which clearly shows the transition between feathered dinosaurs and modern birds.
“This evolution implies that buried deep within the DNA of today’s birds are switched-off genes that control dinosaur-like traits.
