The recent study says, life first originated from the Meteoroids. Around 4.5 billion years ago, of the Earth-sized meteor blasted on the Earth’s surface, thus filtering and transferring the carbon life to our planet. Scientists refer water bodies, the origin of life on Earth as the ‘warm little pond’.
The meteor was rich in carbon, the basic building blocks of a living life. It was responsible for settling down an RNA component having slightly similar functionalities as that of DNA onto Earth. This gave rise to a genetic code of life that went on replicating to form the first human being on Earth.
The idea of “warm little ponds” was first coined by Charles Darwin in the 19th century. Ben Pearce, lead author of the study said, “We have made this statement only after getting an evidence for the same. The research is not feasible but definitely plausible, hence, it’s rather exciting for all of us.”
We are still working hard to get another set of evidence but that’s going to be pretty expensive, he further added.
Darwin’s theory of life cell:
Earlier living cells of human were believed to have RNA a basic genetic material along with DNA. DNA functions as a prototype of the human cell while RNA is responsible for interpreting the code generated by DNA into proteins. It’s also involved in a number of another task including boosting the adaptable nature in cells like decease, development, and aging.
Meteoroids carrying the nucleobases hit the surface of the Earth and relocated the cells in the water bodies of the Earth’s surface. Survival of life on the planet was actually a challenging task. The UV rays coming from the hot star diminished these cells while those settling down deep into the soil remained alive.
Formation of RNA took place just a few years after the meteorite hit, says Pearce and his colleagues. One of the major drawbacks of the study still goes unseen. Authors have still considered the energy. According to the law of thermodynamics, hydrothermal outlets taking place at the surface of the Earth can enhance the life on Earth.
