Really? Newton's ideas are "self evidently true"?
The average person assumes a heavier object falls faster than a lighter one. But from experiment, we know this isn't the case.
The average person assumes that living organisms around him are set and cannot be changed. But from experiment we know selection can cause major changes in organisms.
Evolution is inevitable because:
Organisms are variable
That variability is inherited
Many offspring of organisms die due to the interactions of their variations and the environment
For example:
The Rock pocket mouse of the southwest comes in sandy brown and also black due to the sandy desert being interrupted by the black rock. An easy prediction in evolution. Axiomatic you might say . . .
If you started with a group of many colored mice and created an open topped enclosure with a surface painted white, you can imagine which color of mouse would predominate after a few generations.
When humans choose from the variability, we can create big differences in a short period of time.
Evolution can also be modeled mathematically. One of the common ones is the Hardy-Weinberg equation.
