Then please do so.

You can observe "descent with modifications" and "natural selection" all by yourself, you don't need my help.
On "descent with modifications" simply note that no offspring are identical to their parents.
For "natural selection" simply note that in nature offspring born with defects often don't survive, while those born with something special more often survive and reproduce.
And that's evolution in a nut-shell.
