Evolution in short

Your point in life is to make sure your genes survive for as long as possible in your environment
This means reproducing so your genes can live on when you die.

There are various ways you can help the survival of your genes
increase the chances of procreation
You can compete with the other beings to acquire resources
or you can cooperate with other beings to share resources


While all this is happening, your genes are changing
Mutations happen because of the environment (or by chance?)
All beings are genetically different
variation

These mutations either help you survive in your environment or make it harder.
The mutations that help you survive, logically will be promoted
natural selection



"Back in Darwin's day, a contemporary of his (Herbert Spencer) invented a sound bite for natural selection: he called it 'survival of the fittest,' with 'fit' meaning best adapted-not necessarily the biggest and strongest. Correctly understood, though, natural selection is survival of the fit enough. It is not, in fact, only the individuals who are most perfectly suited to the environment that survive; reproduction, after all, is a matter of degree...
As long as an individual reproduces at all, it is fit, even if some are fitter than others."
