Meteorites could provoke life on Earth and Mars

US, WASHINGTON (ORDO NEWS) — Scientists have only two theories of the origin of life: extraterrestrial delivery and endogenous development. New research provides proof of the first version.

During the study, Japanese scientists modeled the interaction of elements that could play a role in the formation of life after a meteorite falls into the ocean. To do this, they studied the reaction between carbon dioxide, nitrogen, water and iron in a laboratory in which they created “shock conditions”.

Their modeling revealed the formation of amino acids such as glycine and alanine, which arose during shock exposure. These elements are direct components of proteins that catalyze many biological reactions.

The group used carbon dioxide and nitrogen, as they are considered the two main components of the atmosphere on Earth, which existed more than four billion years ago.

The hypothesis that the ocean once existed on Mars also opens up interesting prospects for research. Carbon dioxide and nitrogen were probably the main components of the Martian atmosphere before. Thus, the shock that formed the amino acids could also “give” the ingredients for life on ancient Mars.
