Skydiving for the first time
A man is going skydiving for the first time. After listening to the instructor for what seems like days, he is ready to go.
The man goes up in the airplane and waits to get to the proper altitude. Excited, he jumps out of the airplane. After a bit, he pulls the ripcord. Nothing happens. He tries again. Still nothing. He starts to panic, but remembers his back-up chute. He pulls that cord. Nothing happens. He frantically begins pulling both cords, but to no avail.
Suddenly, he looks down and he can't believe his eyes. Another man is in the air with him, but this guy is going up! Just as the other guy passes by, the skydiver, by this time scared out of his wits, yells, "Hey, do you know anything about skydiving?" The other guy yells back, "No! Do you know anything about gas stoves?"

The Origin of SpeciesIn 1859, The Origin of Species by Means of Natural Selection, Darwin's groundbreaking book, was published in England to great acclaim. The British naturalist, Charles Darwin detailed the scientific evidence he had collected since his voyage on the Beagle in the 1830's. He presented his idea that species are the result of a gradual biological evolution in which nature encourages, through natural selection, the propagation of those species best suited to their environments. He had been prompted to publish at this time by Charles Lyell, who advised him that Alfred Russel Wallace, a naturalist working in Borneo, was approaching the same conclusions. Lyell believed Darwin should publish without further delay to establish priority. [Image: Title page from 1859 edition]
