In a recent subject field , a team of scientists have tried to find out what the DNA of dinosaurs might have been like . The researchers were in search of genetical clues showing how the reptiles were able-bodied to take over the major planet for 180 million age . The squad did n’t redo dinosaur DNA ( noJurassic Park , I ’m afraid ) , but instead worked backwards from the close innovative - day relatives of dinosaur .
As reported inNature Communications , the team used a numerical model to crop out what the ancestor of razz and turtles was like genetically . This common ascendant live 260 million age ago , 20 million years before dinosaurs first emerged . The team was able to trace what chromosome pairs were already in shoes in this out mintage .
" The fogey evidence and now our grounds reinforce the mind that rather than birds and dinosaur being distant relatives , they are one in the same . The birds around us today are dinosaurs , " conduct writer Dr Rebecca O’Connor , from the University of Kent , toldBBC News .
The squad estimates that dinosaurs likely had 80 chromosome ( man have 46 by comparison ) . In apress release , the team argues that having rafts of chromosomes may explicate the diversity of birdie we see , and this could apply to dinosaurs as well .
" We retrieve it generate variation , " older Professor Darren Griffin said . " Having a lot of chromosomes enables dinosaur to shamble their genes around much more than other types of beast . This shamble means that dinosaurs can evolve more quickly and so aid them come through so long as the major planet change . "
The finding advise that the figure of chromosomes in these ancestral wight have not deepen much in New birds . What really changed is the information within each chromosome . Chromosomes are DNA speck that contain all the factor that make a mintage .
The squad argues that the full genome ( the whole 80 chromosomes ) is a extremely unchanging form and the unlike dinosaur species , from theT - rexto the extinct brat birds to the vulgar pigeon , are due to modification in the factor . The genome of aT - rexor a velociraptor would have been very unlike from the one of a chicken at first glance .
