Change Quote by Richard Goldschmidt

“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

“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 decisive step in evolution, the first step toward macroevolution, the step from one species to another, requires another evolutionary method than that of…

“Universally accepted, microevolution has limits for what it can explain. These limits do not reach the center where the controversy lies - the Thesis…

If evolution exists in every living species, likewise so too does devolution.

— Samael Aun Weor

The more highly adapted an organism becomes, the less adaptable it is to any new change.

— Ronald Fisher

A number of well-understood mechanisms, including single gene mutations, produce changes that qualify as macroevolution. These include heterochronic mutations that alter structures by changing…

“He saw that there is a spectrum of variation between species that comes into being slowly, tiny change by tiny change. He realized that…

“Eliminate one species, and another increases in number to take its place”

— Kim Sterelny

It's impossible by micro-mutation to form any new species.

— Richard Goldschmidt

“All living species “adapt.” Indeed, “adaptation” is a distinctive emergent property of life in general. Adaptation means that, over time, the average features of…
