The Origin of Species

Charles Darwin's The Origin of Species, published in 1859, is one of the most controversial books of the 19th century. Although the theory is widely accepted by scientists today, it is still banned in many schools (esp. in southern U.S. states). The full title of the book is On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.

In it, Darwin presents a theory of evolution - a concept that embodies the belief that existing animals and plants are developed by a process of gradual, continuous change from previously existing forms by natural selection. This theory is in most aspects identical to the theories now accepted by scientists. He carefully argues out this theory of evolution of species by natural selection by presenting all the accumulated scientific evidence from his voyage on the HMS Beagle in the 1830s. His theories were opposed to the then-accepted viewpoint of creationism. It is arguably one of the pivotal works in scientific history. Moreover, it was (and still is) eminently readable, even by the non-specialist (although it is very wordy - a good general level of intelligence is a prerequisite for comprehending the arguments and subtle nuances put forth by Darwin).

Darwin, as evidenced by his later work, The Descent of Man, was well aware of the implications such a theory would have on the study of the origins of humanity; consequently, he withheld publication of his accumulated evidence in favour of natural selection for more than a decade. He was eventually forced into publication because of the independent development of a similar theory by Alfred Russel Wallace, who sent Darwin his manuscript in 1858. Darwin's theory of evolution was put forth the following year. It is felt by some that Wallace deserves as much credit as Darwin for the theory of natural selection, and that he has been rather unfairly marginalised from the history of its development.

The theory of evolution was greatly objected to because it made man think.

Alfred Russel Wallace (1823-1913)


Although Wallace independently reached the same conclusion, as Darwin about the “natural selection“ theory, it has usually been Darwin's name alone associated with it. Wallace expressed no resentment at receiving so little credit for his contribution. He remained a gracious man to the last, commenting late in life that his greatest achievement had been to prompt Darwin to publish his own theory.

Darwin's quotes:

"In Science the credit goes to the man who convinces the world, not to the man to whom the idea first occurs."

– Sir Francis Darwin (1848-1925, English botanist, son of Charles Darwin), In: Eugenetics Review (April 1914, "Francis Galton")


I love fools' experiments; I am always making them.

Biology is the only science in which multiplication means the same thing as division.

If Darwin was right, you will probably figure it out in a few million years.

Enzymes are things invented by biologists that explain things which otherwise require harder thinking.

Three freshman-engineering students were sitting around talking between classes, when one brought up the question of who designed the human body.
One of the students insisted that the human body must have been designed by an electrical engineer because of the perfection of the nerves and synapses.
Another disagreed, and exclaimed that it had to have been a mechanical engineer who designed the human body. The system of levers and pulleys is ingenious.
"No," the third student said, "you're both wrong. The human body was designed by an architect. Who else but an architect would have put a toxic waste line through a recreation area?"


One day the zoo-keeper noticed that the orang-utan was reading two books - the Bible and Darwin's The Origin of Species. In surprise he asked the ape, "Why are you reading both those books"?
"Well," said the orang-utang, "I just wanted to know if I was my brother's keeper or my keeper's brother."

A fossil is an extinct animal. The older it is, the more extinct it is.

An unemployed biologist got a new job at the zoo. They offered him to dress up in a gorilla's skin and pretend to be a gorilla so people will keep coming to the zoo.
On his first day on the job, the guy puts on the skin and goes into the cage. The people all cheer to see him. He starts really putting on a show, jumping around, beating his chest and roaring.
During one acrobatic attempt, he loses his balance and crashes through some safety netting, landing square in the middle of the lion cage! As he lies there stunned, the lion roars. He's terrified and starts screaming, "Help, Help!"
The lion races over to him, places his paws on his chest and hisses, "Shut up or we'll both lose our jobs!"



Many dead animals in the past changed to fossils while others preferred to be oil.

A Charles Darwin anecdote:

Charles Darwin saw a beetle and picked it up. He saw a second and picked that one up in the other hand. He then saw a third one, which he really wanted. Not knowing what to do, he shoved one of the ones he was holding into his mouth in order to pick up the third one. The one in the mouth emitted some kind of stuff which made him spit out the beetle and also lose the other two.
