Charles Darwin's law

Charles Darwin is today known for his theory of evolution by natural selection. He industrialized this theory over a whole of years after returning on a 5 year (1831 to 1836) round the world travel on Hms Beagle. The frame of the theory was first presented in a paper read to the Linnean society by Charles Darwin's friends, Sir Charles Lyell and John Dalton Hooker (Darwin himself was unable to attend this presentation of his work because of the modern death of his child son from scarlet fever) on July 1st 1857. Darwin then presented his ideas to a wider public, and at considerably greater length, in his first-rate 1859 book, "On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life", which today is regularly referred to plainly as "On the Origin of Species".

Many habitancy misunderstand what Darwin's theory is about. Perhaps the most base error is that it is a theory of the origin of life ("abiogenesis"), that is not the case - Darwin's theory does not deal with that matter, but rather is only about how successive generations of organisms turn over time ("evolution"). Other base point of blurring about Darwin's work is that he was the first person to suggest the idea of evolution - this is far from the case - evolutionary ideas date back to at least the 6th century Bce (e.g. The Greek philosopher Anaximander). Instead Darwin's great understanding was "natural selection", which is an explanation of how evolution works to yield new species and to generate organisms distinguished to their environments.

Although of policy there are many details and fine points behind the idea of natural selection, the basic idea behind it is beautifully simple. It begins with the observation that children tend to be similar to their parents. From that observation one can state that anything heritable traits are good at helping organisms to survive and reproduce will tend to come to be more base in a population, whereas harmful heritable traits will gradually come to be less and less common. Of course, random changes to heritable traits ("mutations") may also occur, but these too will tend to come to be or less base depending on either they are helpful or harmful. Finally, when we think the heavy age of the Earth, this provides adequate time for the accumulation of tiny improvements in useful heritable traits to yield a great variety of separate organisms - in fact all life on Earth.
