Author of quotes: Jean Baptiste Lamarck

We know that this animal [giraffe], the tallest of mammals, dwells in the heart of Africa, in places where the soil, almost always arid and devoid of herbs, forcing him to climb trees and constantly to strain to reach them. This habit, long maintained in all members of his race, led to the fact that the front legs were longer than the back, and the neck is so stretched, that the giraffe, without standing on his hind legs, raises its head to a height of six meters.

What nature does over long periods of time, we do every day when suddenly changing the environment in which there is some kind of live plant.

Man, blinded by selfishness, it becomes insufficiently prudent, even in regard to his own interests...

In all, working on what nature, she does nothing hastily.
