Primordial soup served up cold

摘要

The hot spot for life on early Earth may have been very cold. Tiny pockets that form inside ice can contain and protect replicating molecules, researchers report September 21 inNature Communications. The paper suggests that life could have sprung from icy slush covering a fresh water lake, rather than a boiling deep-sea hydrothermal vent or the "warm little pond" proposed by Charles Darwin.
