Every species has come into existence coincident both in space and time with a preexisting closely allied species.

In less than eight years "The Origin of Species" has produced conviction in the minds of a majority of the most eminent living men of science. New facts, new problems, new difficulties as they arise are accepted, solved, or removed by this theory; and its principles are illustrated by the progress and conclusions of every well established branch of human knowledge.

I have carefully measured the proboscis of a specimen of [Neococytius] cluentius from South America in the collection of the British Museum, and find it to be nine inches and a quarter long! One from tropical Africa ([Xanthopan] morganii) is seven inches and a half. A species having a proboscis two or three inches longer could reach the nectar in the largest flowers of Angræcum sesquipedale, whose nectaries vary in length from ten to fourteen inches. That such a moth exists in Madagascar may be safely predicted; and naturalists who visit that island should search for it with as much confidence as astronomers searched for the planet Neptune - and they will be equally successful!

Species are merely those strongly marked races or local forms which, when in contact, do not intermix, and when inhabiting distinct areas are generally regarded to have had a separate origin, and to be incapable of producing a fertile hybrid offspring.

Quote of the day
The sea speaks a language polite people never repeat. It is a colossal scavenger slang and has no respect. Is it a terrible thing to be lonely?
