dinosaurs dominate the luck?
evolutionary biology research has been that the dinosaurs rule the roost in the evolutionary process, mainly because dinosaurs had unparalleled compared to other species, the" superiority." However, Hong Kong's Wen Wei Po reported that U.S. and British scientists, the latest fossil findings challenge the traditional theory that the dinosaurs to dominate may be entirely luck.


researcher at Columbia University and Bristol Brussat University with the cooperation and attempts to study the fossil record to determine the Triassic (251 million years ago to 199 million years ago), the main competitor of the early dinosaurs and dragons inlaid ankle early class of the evolutionary relationship between.


research team found that early dinosaurs and dragons inlaid ankle class time evolution is actually in parallel, the evolution rate is almost no difference. This makes them very surprised, because the envisaged dinosaur order to dominate in the future, then the dinosaurs in the Triassic when the rate of evolution should be faster than the early class of mosaic dragon ankle.


Indeed, when the momentum of the evolution of the latter had a slight advantage, evolutionary diversity is better than dinosaurs. Overall, in the presence of dinosaurs in the first 3000 million years, dinosaurs and dragons inlaid ankle early in the evolution of class overlap period, share the same living space, looks very similar.


scientists said the results mean the beginning of the dragon is embedded ankle class suffered a sudden extinction of an accident, not in competition with the evolution of dinosaurs defeated.


According to analysis, in about 2 million years ago ago, the Earth may As the asteroid impact and other reasons, experienced a rapid climate change. Scientists said that this led to a three-Triassic mass extinction occurred at the end, mosaic dragon ankle early class in addition to a handful of ancestors of modern crocodiles, the other is destroyed, but unexpectedly survived the dinosaurs.
