Ученые выдвинули новую гипотезу возникновения жизни на ЗемлеLife on Earth is “lit up” because of a collision in space

Probable scenario of the origin of carbon, nitrogen and sulfur in the silicate part of the Earth not appear funny, as earlier, most likely a meteor stream, was the cause of the origin of the bacteria.

There are many theories about how life originated on Earth, many of which try to explain how our planet has the ingredients for life: elements like carbon and nitrogen. One new study suggests that a previously unknown collision helped “to light” life on Earth.

Previously, scientists thought that meteorites brought life-giving elements on Earth. Although isotopic signatures of these elements on the planet coincide with these objects, the ratio of carbon and nitrogen is not entirely true. While the meteors supposedly brought to the Earth elements that are critical for life (known as carbonaceous chondrites) contain 20 parts carbon to every part nitrogen, this ratio is around 40-1 on Earth. Instead, these important elements could be in a collision, says a group of petrologic from rice University. Scientists know that the long-standing clash between the ancient planet Earth and an object the size of Mars created the moon, that same drummer may also gave us the elements for sparking life, they say.

To come to this conclusion, the research team created a simulation of this event on the basis of a series of experiments in which they tested the behavior of carbon, nitrogen, and sulfur in the process of forming a core on a rocky planet. Then the team simulated high pressures and temperatures during core formation, and estimated how much carbon or nitrogen may be on the planet the size of Mars with a core, rich in sulfur. Through their simulation, along with the known ratios and concentrations of elements on Earth, the team found that instead of the rain of meteorites, delivering essential elements, a more likely explanation is that they came from.

“The results of our simulation showed that the most likely scenario for the origin of carbon, nitrogen and sulfur in the silicate part of the Earth is when these elements are brought the size of Mars (8-10% by weight of a modern Earth),” says Rajdeep Dasgupta, co-author of the article in an email, stressing that life on Earth is “flashed” because of the violent collisions in space.

In addition, this planet probably would have a core, rich in sulfur. The results do not cover the question of how life originated on Earth, but they begin to answer the question of how the ingredients for life could appear on earth.
“There are many unanswered questions about how to actually life originated. Our study, however, provides a mechanism for obtaining the raw materials necessary for life recipe, ” said Dasgupta.

Thus, there is a probability of collisions in space and hence may be somewhere there is a prototype of life on Earth.
