Evolution. Why do people still talk about evolution in wildly inappropriate terms? Using words like designed, breed for, etc. It's all tosh.

Evolution breaks down to the simplest computer-program style flow chart structure possible. One question and two answers to 'if yes goto' and 'if no goto'.

The question is: 'Does it reproduce?'. If yes goto 'does it reproduce?' If no goto 'end.'

And that's all. Nothing more is required to understand evolution. Nothing. Mutations occur. Things reproduce or they don't. All the rest is consequences.
