Scientists Say They May Have Just Figured Out the Origin of Life
How did the building blocks of life come together to spawn the first organisms? It's one of the most longstanding questions in biology — and scientists just got a major clue. In a new study published in the journal Nature, a team of biologists say they've demonstrated how RNA molecules and amino acids could combine, by purely random interactions, to form proteins — the tireless molecules that are essential for carrying out nearly all of a cell's functions. Proteins don't replicate themselves b
