Origin of Life on Earth: 'Natural' Asymmetry of Biological Molecules May Have Come from Space


www.sciencedaily.com

This result therefore supports the hypothesis that the asymmetry of biological molecules on Earth has a cosmic origin. The researchers also suggest that the solar nebula formed in a region of massive stars.

This work has just been published online on the web site of The Astrophysical Journal Letters.

The chirality or 'handedness' of molecules such as sugars and proteins on earth and the fact that only a single form exists across all live is quite intersting.

The fact that only one form of each predominates, when either type can exist, has yet to be definitively explained. Local conditions during evolution of early life have been posited as explanations.

This isn't LGM or anything of that sort, but it lends support toward the same chirality being found in the same molecules elsewhere within the universe.

I doubt that if we were to stumble on a type of life that was not immediately apparent, and vastly different from our own, that we would recognize it. Though this is interesting news.

It's crazy to think about the fact that even though we have made decent recent advancements in technology in the past couple hundred years, we literally know almost NOTHING about the universe. We believe that we are intelligent and all knowing because we can have conversations with each other and drive automobiles/fly airplanes, but the sad reality is that we still have a loooong way to go. The universe is unfathomably massive, containing some 100 billions known galaxies, each containing about 100 billion stars/planets, and we are just one of these planets in one solar system in one galaxy. Humans have only made it as far as the Moon, yet in society some people have this misconception that we know everything about everything already. It just blows my mind to take a minute and think about the vast amount of information and experiences that we will never get to encounter. Even if humanity makes it another 1 million years (Which I believe to be impossible at the rate we're going), I bet there will still be countless questions that we still will not have answered, and will be up for debate.

Surely this shared feature is just evidence that all life on earth, as we know it, shares a common ancestor?

How does that indicate that said common ancestor originated elsewhere?

If all life on this world came from space, or is of "cosmic origin" that would lend some credence to the theory of creation.

If life came here from somewhere else and didn't evolve from our own terrestrial muck... How did it get here?

More importantly... who or what sent it here and why?
