Why different places became the size of the elephants

Great clothes and sharp ties and tall talls like rams like rams that are walking right there, smaller plenty of pigs with pigs with a larger tongue.

Now, scientists have been because they became very big, and why not embraced were not cluster of new surveys Science.

Today, two types of low types are in Central and South America. But the past, many of the smooth colors that have taken in America, all the way from Argentina to Canada. As modern sloths, the least varieties were a tree. But big slots?

“He looks like little stains,” Rachel NarDucci, Vertuci, Vertebrate Paleontology Austimed Florian profile’s Florian history and economy, in statement.

The biggest sloots did not rise many trees, at risk of falling on their death. Instead, he survived the fear of fear; The greatest appearance had long shells, which uses their jewels in the earth and stones. But exactly why she just had a secret.

To find out how the purchase experience encountered adults, researchers checked an old DNA and compared more than 400 items from the environment of the natural estate of life. The researchers made a slope to 35 million slopes. And, because scientists were interested in lovingly as the minor area had its size, counted their weights using the basic measurements.

The researchers thought that the old world’s past was the most important thing. The first fifty-eight years ago, the first parent, in what was now Argentina, was the same as a big dog. Sloths have not changed much of the size of 20 million years, and they sit down. Then, a hot period of a summer about 16 years ago, slopes that are converted by small rites due to their value to be cold.

Then, as the world is settled down – what’s been going on to go to 50 million years of age that began to be bigger and large. He also started to relocate, exiting from Argentina in the northern North and South America, even to Alaska and Canada.

The new location has been encountered by the pressures that Sloth had met, in a session, scratching. This new size enhanced the heat and maintain secure to children.

“That would have allowed them to save energy and water and succeeded in a thorough control of no small amounts of things,” he said. “And if you are in the grass protection, you need protection, and to be adulterated by them.”

He arrived on their largest palm of the Ice Pensalene, which surrounded 3 million years to 12,000 years ago, soon lasted.

Not only scientists don’t know all the reason for the sweet places ended, but they have some suggestions. The first people moved to America 20,000 years ago. The most attractive places with many places should be prime, the target of the early, and sitting down started to be responsible.

The main slopes were the first to go, but the minor site did not escape. When going on time, many nations of the trees have vanished, too. Two colors had survived in the Caribbean to about 4,500 years ago – until people moved them. Now, a small area of ​​the smaller places exceeds in Central and South America, but grateful he does not sit on the menu.
