An international team of scientists has discovered the greatest absence of evolution ever reported — a type of deep-sea microorganism that appears not to have evolved over more than 2 billion years.
“It seems astounding that life has not evolved for more than 2 billion years — nearly half the history of the Earth,” J. William Schopf, a professor at the University of California at Los Angeles, and the study’s lead author, said in a statement.
“Given that evolution is a fact, this lack of evolution needs to be explained.”
