The origin of life on Earth is a truly controversial topic, in which even religion has had an impact. Science, for its part, has proposed various theories that suggest that life may have originated on meteorites from another part of the universe, and upon arrival found conditions conducive to thriving.
It doesn’t tell us how it started or where it came from, but it does give us a glimpse into the possible reasons why we are here.
No matter how far-fetched a theory is, it must be disproved, so that it must cease to be one of many possibilities, and that is why, as strange as it may seem, unlike the example of the “space debauchee” …
Not long ago, an article was published with decades of information that caused quite a stir due to the nature of its approaches. “The Cause of the Cambrian Explosion – Terrestrial or Cosmic?” That article is titled.
Although richly referenced and peer-reviewed, it presents approaches somewhat removed from what is currently thought.
Scientist Stephen Fleischfrecher gives us an insight into two great scientists, Edward Steele and Chandra Wickramasinghe.
On the one hand, Steele proposes evolution as the acquisition of genetic changes determined by the influence of the environment rather than random mutations, which he calls metallargism.
On the other hand, Wickramasinghe confirms Fred Hoyle’s hypothesis about the production of organic carbon molecules from interstellar dust.
The complexity and work involved in studying cometary biology suggests that evolution was affected by the fact that the biochemistry described in the formation of the first amino acids did not occur on Earth.
Wickramasinghe notes, “Comets are the carriers and distributors of life in the universe, and life on Earth originated and developed as a result of the contributions of comets.” However, his approach goes beyond a few amino acids placed in space and sent to Earth, but he notes that even complex cellular forms such as viruses and a eukaryotic cell may have arrived on Earth given the right conditions where they could have proliferated.
The shower of retroviruses that signal their arrival play an active role in this, as they have influenced evolution for about 500 million years and are responsible for the great diversification of life.
This was achieved by combining parts of the genetic material with life on Earth.
Not to mention that the group of cephalopods that appeared in the oceans at that time branched out into many species of different shapes and sizes in a short period of time. But their complete genomes in eggs may have arrived in what they describe as “ice bolites several hundred million years ago,” not thinking the creature’s origin could have been extraterrestrial, but that complex forms may have actually come with it. .
These arguments are always valid, and there is always the possibility that in the future we will find some truth in many of these facts.
This is a very interesting article published in the journal Advances in Biophysics and Molecular Biology.
