Enzymes in Bacteria and Archaea Are So Dissimilar There Must Be “Two Origins of Life”
Don’t get distracted by wondering how the extreme heat near a vent (a toasty 750° F or more inside the vent) wouldn’t quickly break down organic molecules. Source

A groundbreaking study hints at a hazy boundary between “life” and “non-life,” as well as two distinct origins of biology on Earth
Scientists probing life’s deepest origins have uncovered evidence that the first free-living cells may have emerged not once, but twice. The findings suggest a striking possibility...
The origin of life is one of the biggest mysteries left in science. Now a group of researchers says there wasn't just one originsttr, there were two. And I want to explain why, des...
The origin of life has fascinated humanity throughout history. Myths, religions and philosophies have all sought to explain how living beings came into existence, often blending fa...

That’s now just 1 billion years for all the apparatus to hit on the lucky combination randomly, unless we start with design principles. Source
Earth’s oldest eukaryotic fossils may illuminate both the rise of complex life and the search for life elsewhere. Searching for life on Mars or the icy moons Europa and Enceladus m...
A tiny chemical difference makes RNA better than DNA at forming liquid-like droplets under high temperatures and acidic conditions. One of the biggest puzzles in origin of life res...

A rare meteorite that crashed through a New Jersey roof contains evidence of ancient salty fluids, organic compounds, and amino acids from a primitive asteroid. Its pristine chemis...
Learn how a meteorite that struck a home in New Jersey has given scientists a chance to find molecules that played a crucial role in the origins of life.
Researchers at Hebrew University report a simple chemical link that could help explain how early Earth chemistry transitioned toward cell-like organization. Their work shows that f...
Ученые поставили под сомнение один из наиболее известных сценариев появления жизни на Земле. Новые геохимические расчеты указывают, что на дне древнего океана могло не быть условий...
Followers of the debate between intelligent design and Darwinian evolution will be familiar with Christoph Adami's example. Source
Ancient microbes appear to have used molybdenum as far back as 3.7 billion years ago, despite the metal being scarce in Earth’s early oceans. Scientists funded by NASA have found t...
