DNA analysis can decode how dinosaurs looked like



Scientists have decoded the general DNA structure of well-known dinosaur species, such as the Velociraptor and T-rex, an advantage that can help to get a true picture of what the prehistoric predators looked like in reality.

Researchers led by Darren Griffin from the University of Kent in the United Kingdom compared the genomes of different species, mainly birds and turtles.

They extrapolated the likely genome structure of a common common ancestor of birds and turtles that lived about 260 million years ago – 20 million years before the dinosaurs first appeared.

The research, published in the journal Nature Communications, traced how chromosomes changed from a reptile ancestor to the present in evolutionary times.

The team discovered that although the individual chromosomes rearranged their genes internally, this did not occur much between the chromosomes.

Birds – which are themselves living dinosaurs – have many chromosomes in comparison with most other species and that is probably one of the reasons why they are so diverse.

The research suggests that the pattern of chromosomes observed in early emerging dinosaurs and later theropods is comparable to that of most birds and that it can again explain their great diversity.

The discovery suggests that if scientists had the opportunity to make a chromosome preparation from a theropoda dinosaur, it might look very similar to a modern ostrich, duck or chicken.
