Charles Darwin Species Quotations

I am almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable.

Intelligence is based on how efficient a species became at doing the things they need to survive.

We behold the face of nature bright with gladness.

Why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms.

Multiply, vary, let the strongest live and the weakest die.

A language, like a species, when extinct, never ... reappears.

Mere chance ... alone would never account for so habitual and large an amount of difference as that between varieties of the same species.

... not one living species will transmit its unaltered likeness to a distant futurity.

Man selects only for his own good: Nature only for that of the being which she tends.

Great is the power of steady misrepresentation

One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.
