Antibiotic-resistant microbes have an ancestry that dates back hundreds of millions of years, even before dinosaurs roamed our planet, a new study says.
Famed paleontologist Jack Horner of Montana State University worked the excavation site.
In a 2011 development, ten leading universities and institutes including Harvard, the University of Manchester, and the University of Pennsylvania published in PLo S One, a peer-reviewed journal, that they had verified that presumed dinosaur material is indeed original biological tissue from a dinosaur!
However, they cautioned against drawing any conclusions about the dinosaur’s intelligence.acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large muscles of a weightlifter).adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.Normally, brain tissue would have quickly decayed, but it is thought the dying animal fell into a bog and the organ was pickled by the highly acidic and low-oxygen water.One of the researchers, Dr Alex Liu, of Cambridge University's Department of Earth Sciences, said: “The chances of preserving brain tissue are incredibly small, so the discovery of this specimen is astonishing.” The stone was found by fossil hunter Jamie Hiscocks, near Bexhill in Sussex in 2004, and he sent it to the late Professor Martin Brasier, of Oxford University.
