Scientists come closer to solving the mystery of the origin of life

Ученые приблизились к разгадке тайны возникновения жизни

Biologists in the laboratory repeated the stages of evolution of life from inanimate nature.

Scientists have made good progress towards solving the mystery of the origin of life on Earth, they say in Nature Communications.

The evolutionist Nicholas HUD of Georgia Institute of Technology said that together with colleagues, he was able to replicate the evolution of life from inanimate nature, using two simple organic molecules – barbituric acid and aromatic hydrocarbon melamine.

They got a set of nitrogenous bases, very similar to adenine, guanine, cytosine and uracil – the “building blocks” of RNA and DNA.

They argue that the C-BMP and MMP (as scientists have called the resulting “bricks”) are well associated with ribose and other sugars and had even formed pairs of two opposite to each other on value grounds, as it happens in real double chains of DNA and RNA.

As scholars have noted, the similarity between these nitrogenous bases in DNA and RNA is so great that in principle they can claim their chemical parents.

Scientists them have no idea how it happened and they can’t explain the mechanism of occurrence of “protobuf” DNA.

“But today we are approaching the molecules, which formed the basis of the first living beings,” says a colleague Hada RAM Krishnamurti.

In February, scientists from the Massachusetts Institute of technology said that the first animal on Earth was a sea sponge.

Previously, scientists found that the Earth has experienced the flash of a supernova about two million years ago, which could affect the climate and thus change the course of evolution of many species on Earth.

According to scientists, the cause of the first extinction on Earth that took place during the ediacaran period (Precambrian), was a series of magnetic revolutions of our planets.
