GRADUAL EVOLUTION. “Since the origin of evolutionary science, biologists have insisted that adaptation is an achingly slow process. ‘ Natura non facit saltum ‘ (nature does not take leaps) was a favourite incantation of Charles Darwin. As the combined power of genetic mutation and natural selection became better appreciated in the 1930s and 1940s, theorists solidified a gradualist doctrine: adaptation must rely on innumerable genetic changes, each with effects so small that any attempt to catch them experimentally was considered futile.”
