“NASA’s ENIGMA (Evolution of Nanomachines In Geospheres and Microbial Ancestors) research team,” evolutionary biologist Paul Falkowski told The Daily Galaxy, “is focused on answering a single, compelling question in astrobiology: How did proteins evolve to become the predominant catalysts of life on Earth?
Before life appeared on land some 400 million years ago, all life on Earth including the mind evolved in the sea. Astronomers have recently conjectured that blue exoplanets with endless oceans may be orbiting many of the Milky Way’s one trillion stars. In 2016, for example, Kepler astronomers discovered planets that are unlike anything in our solar system –a “water world” planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — their surfaces completely covered by an endless global ocean with no land or mountains in sight.
