Evolution Quote by Richard Goldschmidt

No matter how numerous they may be, mutations do not produce any kind of evolution.

— Pierre-Paul Grasse

“New mutations don't create new species; they create offspring that are impaired.”

— Lynn Margulis

“While micro-evolution--change within species--has been observed in the laboratory, macro-evolution--change from one species to another has not, and never will be.”

— Bob Beasley

With the advent of genetic engineering the time required for the evolution of new species may literally collapse.

— Dee Hock

Not one change of species into another is on record ... we cannot prove that a single species has been changed.

— Charles Darwin

I think it inevitably follows, that as new species in the course of time are formed through natural selection, others will become rarer and…

— Charles Darwin

It is good to keep in mind ... that nobody has ever succeeded in producing even one new species by the accumulation of micromutations.…

— Richard Goldschmidt

“Genetics might be adequate for explaining microevolution, but microevolutionary changes in gene frequency were not seen as able to turn a reptile into a…

— Scott F. Gilbert

The facts of microevolution [change within the species] do not suffice for an understanding of macroevolution [theorized change from one species to another].

— Richard Goldschmidt

That natural selection can produce changes within a type is disputed by no one, not even the staunchest creationist. But that it can transform…

— Robert J. Sawyer

Mutations are exciting, there aren't nearly enough of them.

— Doug Stanhope

I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed…
