Biology Quote by Steven Johnson

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

— James Lovelock

D.N.A. sequences change by mutations, and the idea behind the molecular clock is that those changes occur at, more or less, a constant rate,…

— Mark Stoneking

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

— Doug Stanhope

How comes it to pass, if they be only moved by chance and accident, that such regular mutations and generations should be begotten by…

— John Smith

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

— Lynn Margulis

Life has survived for more than three billion years because it is robust, and almost no mutations can easily outwit the defense mechanisms built…

— Lawrence M. Krauss

“Evolution wasn’t a blueprint; it was a series of mistakes that occasionally turned out to be beneficial. And the doctor knew those were few…

— Evan C. Currie

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

— Lynn Margulis

“The bradys must hold that, on the average, cumulative selection has to add a little information to the genome at each step. But of…

— Lee Spetner

I think, with every kind of creature and every kind of human, there is no better. We're all just mutations, and I think that…

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…

— Kenneth R. Miller

After observing mutations in fruit flies for many years, Professes Goldschmidt fell into despair. The changes, he lamented, were so hopelessly micro [insignificant] that…
