DNA study: solves Darwinian puzzles.When Charles Darwin, the same Mr. Evolution, did not know what to do with the fossils he saw in Patagonia, he sent them to his friend the renowned paleontologist Richard Owen was also perplexed. The bones looked different from everything he knew, Michael Hofreiter, lead author of a study published in Nature Communications that has finally found a place in the tree of life for what Darwin calls the strangest animal ever discovered.Imagine a camel without a hump, with its feet like a thin rhinoceros and shaped like a saiga antelope head, Hofreiter, a professor at the University of Potsdam. Macrauquenia patachonica literally, the long neck flame also had a long, rubbery snout and with its high nostrils in the skull just above its eyes. For nearly two centuries, biologists and taxonomists discussed the pedigree of this strange beast, which weighed between 400 and 500 kilos, lived in open landscapes, and snacked on grass and leaves. However, its heterogeneous body characteristics, and a shortage of DNA tests, make it almost impossible to determine whether M. patachonica was actually related to the flame after which it was named.As it turns out, not really. A new type of genetic analysis revealed that Macrauchenia looked more like an old order of placenta known as perisodactyls, which includes horses, rhinoceroses and tapirs. #Darwinian #Evolution #fossils #discovered #biologists #characteristics #genealogical #life #ymasciencia
