The team proposed that a precursor to that cellular pump evolved in the membranes of the proto-cells.The membrane started out very leaky, but over time, the membranes would have slowly closed, preventing much larger sodium particles from leaving the cell while smaller protons could still slip through.It is only when one toils and sweats it out that success is nourished and sustained.

Deep-sea start Many scientists think life got its start around 3.7 billion years ago in deep-sea hydrothermal vents.

But figuring out just how complex, carbon-based life formed in that primordial stew has been tricky.

This is really cool, novel stuff," Jan Amend, a researcher at the University of Southern California, who was not involved in the study, wrote in an email to Live Science.

The study reflects the increasingly popular idea that a simple, everyday source of power, not a rare occurrence like a lightning strike, could have provided the power to initially create life, he said.

That battery then powered the chemical transformation of carbon dioxide and hydrogen into simple carbon-based molecules such as amino acids or proteins.

Eventually that gradient drove the creation of cellular membranes, complicated proteins and ribonucleic acid (RNA), a molecule similar to DNA.

There is no human being on Earth, strong, powerful, wise or rich, who has not experienced, struggle, suffering or failure.

No doubt, life is beautiful and every moment – a celebration of being alive, but one should be always ready to face adversity and challenges.

Leaving the vents At that point, primitive cells used the thin, serpentine walls of the vent to corral the new carbon-based molecules together into precursors of cells and used the charge gradient in the environment to power the building of more complex organic chemicals.

But in order to leave the vent, primitive cells would have needed some way to carry a power-producing gradient with them — think battery pack.
