Recent studies by American research workers have demonstrated that life arose on the Earth for 300 million years earlier than is generally assumed. To such conclusion experts have come, studying ancient crystals of zircon from Western Australia.
Researchers from Stanford and institutions of California in Los Angeles discovered that life arose on the earth 4.1 billion years ago. That is 300 million years before it's common knowledge in modern science, tells Reuters.
To such conclusion scientists have come in the study of ancient zircon crystals discovered in Western Australia. They identified the carbon zone, which represent the results of life then existing in biological organisms.
"In the course of our work established, that Australian found in crystals of the isotopes of carbon by 300 million years surpass those their own age that were discovered in ancient geological rocks in the South-West Greenland", - said the head of research mark Harrison.
Based on the study of ancient fossils has traditionally been that life on Earth originated about 3.8 billion years ago as single-celled creatures. Approximately, humans appeared about 200 thousand years ago.
Previously, scientists have informed that the population of the earth left to live on Earth about billion years. It turns out the planet's core loses heat much more slowly than it was ever before. Specifically the moment characterizes the existence of a magnetic field. In this regard, researchers imply that the earthlings enough heat for another billion years.
