Origin & Evolution of Life: August 2018

How did life arise on Earth? Rutgers researchers have found among the first and perhaps only hard evidence that simple protein catalysts - essential for cells, the building blocks of life, to function - may have existed when life began.

Estimates of the time at which life arose on Earth make use of two types of evidence. First, astrophysical and geophysical studies provide a timescale for the formation of Earth and the Moon, for large impact events on early Earth, and for the cooling of the early magma ocean.
