Volkswagen-sized armadillo armored mammal ancestor

#Cosmoread: Glyptodon, an ancient armored creature the size of a Volkswagen Beetle, a new genetic analysis shows that it is closely related to the modern-day armadillos.

Glyptodonts roamed the Earth for millions of years until they nearly went extinct during the last ice age 10,000 years ago. Club like armored tail of the animal, the sheer size and the Charles Darwin collected several significant bony shell of the first known specimens in the early 1830s have bewitched. However glyptodont looked like a giant armadillo, scientists how it fit into the family tree were not sure yet Armadillo, the researchers said.

“Data is an enigmatic creature that has fascinated many, but always focuses on family ties was shrouded in mystery,” said study researcher Hendrik Poinar, an evolutionary geneticist and physical anthropologist, said in a statement. “Glyptodont a giant armadillo or a fused bony exoskeleton was the odd branch?”

Group of the angradnt Glyptodonts mammal

The angradnt Glyptodonts mammal group, the anteaters, tree sloths, extinct ground sloths, extinct pampatheres (a little armadillolike creature) and includes part of the armadillo, but its relationship to these animals had eluded scientists.

Now, a genetic analysis shows that glyptodont nestled deep within the family and a close relative of armadillos like should be treated, the researchers said.

“Glyptodonts, in fact, descendants of an extinct around 35 million years ago likely originated Armadillo [diversification] represent within,” Poinar, McMaster University McMaster Ancient DNA Centre in Canada has said the director.

Poinar glyptodont scientists collect samples to be working with an international team; Doedicurus bony shell of a 12,000-year-old, one of the largest on record glyptodonts – ancient DNA extraction techniques used on a sample.

Analysis of the sample, has been found in Argentina, and to remove them to sequence mitochondrial DNA (genetic data passed down through the maternal line) allowed. Then, they Angradnt group mitochondrial DNA of living compared with other mammals.

“Ancient DNA genealogy situation such as the ability to solve a number of questions – or evolutionary relationship – extinct mammals, but often its usable DNA from fossil samples is very difficult to achieve,” Poinar said. “In this particular case, we fish out pieces of DNA and mitochondrial genomes to reconstruct the technical tricks used.”

An additional analysis suggested that the last common ancestor shared by glyptodont and modern armadillo weighed only 13 lbs. (6 kg), showing that glyptodont increased manifold in comparison with its predecessor. Since the fossil record glyptodontsappear once weighed about 176 lbs, this supports the idea. (80 kg) before they evolved into creatures weighing about 4,400 pounds. (2,000 kg) Pleistocene, during the period before the last ice age.
