Big Picture Science

A new the­o­ry about life’s ori­gins updates Darwin’s warm lit­tle pond. Sci­en­tists say they’ve cre­at­ed the build­ing blocks of biol­o­gy in steam­ing hot springs. Mean­while, we vis­it a NASA lab where sci­en­tists sim­u­late deep-sea vent chem­istry to pro­duce the type of envi­ron­ment that might spawn life. Which site is best suit­ed for pro­duc­ing biol­o­gy from chemistry?

Find out how the con­di­tions of the ear­ly Earth were dif­fer­ent from today, how mete­ors seed­ed Earth with organ­ics and a provoca­tive idea that life arose as an inevitable con­se­quence of mat­ter shape-shift­ing to dis­si­pate heat. Could physics be the dri­ving force behind life’s emergence?
