It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change, that lives within the means available and works co-operatively against common threats.

The world will not be inherited by the strongest, it will be inherited by those most able to change.

Endless forms most beautiful and most wonderful have been, and are being evolved

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

It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present. But if (and oh! what a big if!) we could conceive in some warm little pond, with all sorts of ammonia and phosphoric salts, light, heat, electricity, &c., present, that a proteine compound was chemically formed ready to undergo stillmore complex changes, at the present day such matter would be instantly devoured or absorbed, which would not have been the case before living creatures were formed.

Even the humblest mammal's strong sexual, parental, and social instincts give rise to 'do unto others as yourself' and 'love thy neighbor as thyself'.

Man is developed from an ovule, about 125th of an inch in diameter, which differs in no respect from the ovules of other animals.
