Among biologists, few questions have been debated as fiercely as the origin of life.
How did self-sustaining organisms, capable of transforming molecules to capture energy, arise on the primitive Earth?
A new study challenges the assumption that all #life descended from one free-living cell.
Instead, it suggests that two microbial lineages, the #bacteria and #archaea, evolved independently from a #primordial, nonliving ancestor.

Dr. Dave Explains talks about a new protocell synthesized in a lab. This is yet another demonstration, that life is just chemistry.

“A strand of RNA just 45 nucleotides long has been discovered to perform two key reactions required for self-replication. The molecule, which is a kind of RNA enzyme, offers a tantalising clue towards understanding the origin of life, namely how non-living chemistry on prebiotic Earth started to self-replicate and evolve.”

Sulfur exacts a brutal toll for its extraction, but guides the electricity that drives all life.

The last universal common ancestor lived off #hydrogen gas and carbon dioxide, boasted a genome as large as that of some modern #bacteria, and already had an immune system
Its genomic complexity suggests that it was one of many lineages living about 4.2 billion years ago, a turbulent time early in Earth’s history and long thought too harsh for life to flourish.
#Life evolved from a simple replicator into something resembling modern microbes very quickly.

Ancient #Earth was nothing like our current home.
It was a much more hostile place; rich in metallic iron with an #atmosphere containing hydrogen and methane.
These molecules contain an important clue to how #life was initially formed.
When exposed to solar #ultraviolet radiation, they undergo a chemical reaction that produces organics: precursors to essential biomolecules, such as amino acids and nucleic acids.

The nature of the last universal common ancestor (#LUCA) have been the subject of vigorous debate across diverse disciplines.
Age estimates for LUCA are usually based on the fossil record, varying with every reinterpretation while #metabolism has proven equally contentious.
New results indicate that LUCA lived ~4.2 Ga ago and had a genome of at least 2.5 Mb, encoding around 2600 #proteins.

Within a few billion years atoms formed, then stars formed from atoms, galaxies formed from stars and gas, our Sun formed, soon followed by our Earth, about 4.6 billion years ago.
#Abiogenesis is the natural process by which life arises from non-living matter, such as simple organic compounds. The prevailing scientific hypothesis is that the transition from non-living to living entities on Earth was not a single event, but a process of increasing complexity.
