New Theory on How Life came to Earth ? |

Shedding new light on how life began on Earth, scientists, researcher, have proposed a new set of cosmic chemical reactions that could have contributed to the formation of life on our planet.
The researchers found that methanol, an abundant derivative of methane and better known on Earth as ?wood alcohol?, is more reactive than methane itself.
Through experiments and calculations, they demonstrated that methanol could give rise to varied hydrocarbons, their derivatives and products, including their ions (carbocation and carbanions), which have been observed in outer space.
Researchers from the chemistry department at the University of South Carolina (USC) believe that when these hydrocarbons and other products were transported to Earth by asteroids or comets, they continued to evolve in the planet?s unique ?goldilocks? conditions – liquid water, a breathable atmosphere and moderate temperatures – ultimately leading to life as we know it.
In the earliest minutes of the universe?s formation, hydrogen and helium were formed from the energy of the big bang.
All of the other elements developed later in the hot interiors of new stars through the transformation of hydrogen into carbon, nitrogen, oxygen and others.
A few million years later, supernova explosions in these stars flung elements into the surrounding space, forming water and hydrocarbons – compounds containing carbon and hydrogen such as methane and methanol.
?How more complex hydrocarbons evolved, including those that would eventually lead to life on Earth, remains an open question,? the authors noted in an article appeared in the Journal of the American Chemical Society.

Thank You all , really its confusion with different theories

Origin and Evolution of life in Earth is a miracle and it's always interesting to know new findings about this. Wow! its interesting to know cosmic chemical reactions involving methanol and other hydrocarbon derivatives are supposed to be the causes for livable earth.
Thank you for sharing this interesting finding dear Sujan :)

A very interesting theory indeed. But my mind is still abounded with various queries regarding it.
Thank you for sharing this article.

This is fascinating! Thank you for sharing this article. I think life origins on Earth will always be a subject of speculation.

thanks or sharing..
still it is questionable to know exactly how the life gets originated ?

Thanks for sharing details on Evolution of Earth. As part of one of my Biology chapter, I am also reading different theories related to Earth's evolution.
