John Green Quotes

Humans are mutants, everything's a mutant - things that evolve.

Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution.

All life evolves by the differential survival of replicating entities.

The secrets of evolution are death and time-the deaths of enormous numbers of lifeforms that were imperfectly adapted to the environment; and time for a long succession of small mutations.

Mutation is random; natural selection is the very opposite of random.

Evolution doesn't care about what makes sense; it cares about what works

There's nothing nonsensical about saying that what would evolve if Darwinian selection has its head is something that you don't want to happen. And I could easily imagine trying to go against Darwinism.

Evolution is the most popular way we have for dealing with change.

I'm here as a product of process of evolution, which doesn't make very many exceptions. And which rates life relatively cheaply.

Evolution is a tinkerer.

Natural selection certainly operates. It explains how bacteria will gain antibiotic resistance; it will explain how insects get insecticide resistance, but it doesn't explain how you get bacteria or insects in the first place.

First, Darwinian theory tells us how a certain amount of diversity in life forms can develop once we have various types of complex living organisms already in existence.

When I see how fast technology is advancing, my mind thinks of evolution and how organisms also have to evolve or adapt in order to, in their case, survive.

Pretty much every plant and animal alive today is the result of eons of natural cross-breeding.

The idea that you would affect evolution is a very profound thing.

The proof of evolution lies in those adaptations that arise from improbable foundations.

Natural selection is not evolution.

Natural selection eliminates and maybe maintains, but it doesn't create.

As Darwin himself was at pains to point out, natural selection is all about differential survival within species, not between them.

New gene pools are generated in every generation, and evolution takes place because the successful individuals produced by these gene pools give rise to the next generation.

Biologically the species is the accumulation of the experiments of all its successful individuals since the beginning.

It is essential for genetic material to be able to make exact copies of itself; otherwise growth would produce disorder, life could not originate, and favourable forms would not be perpetuated by natural selection.

We are the product of 4.5 billion years of fortuitous, slow biological evolution. There is no reason to think that the evolutionary process has stopped. Man is a transitional animal. He is not the climax of creation.

I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection.

Evolution, as such, is no longer a theory for a modern author. It is as much a fact as that the earth revolves around the sun.
