“It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.

In the struggle for survival, the fittest win out at the expense of their rivals because they succeed in adapting themselves best to their environment.”

– great quote, but was NOT Charles Darwin

In 1963 Leon C. Megginson delivered a speech that contained a passage presenting his interpretation of Charles Darwin’s ideas. Megginson did not claim that he was quoting the words of Darwin. Nevertheless, over time, in a multistep process this passage has been simplified, shortened, altered, and reassigned directly to Darwin.

This is a great example of asymmetric information.
