Evolution does not learn from mistakes

The Darwin awards acknowledge people who improve the gene pool of humanity, by accidently removing themselves from it. While winning the award guarantees that the same individual will not try it again, nothing guarentees that the same actions won't be tried again by someone else.

The same thing is true in business.

Evolution only learns from success.

When something is attempted that does not work, it is tough for others to learn from it. Success on the other hand continues, and can be emulated and improved on.
