You lose. Now, show me your proof, sinec I provided proof of mine, otherwise you're dismissed.
The way evolution works would be like if you had a prop plane and you had to covert that to a jet by simply adding equipment to the prop plane rather than scraping and replacing parts. You could leave some parts on as unused, but you could not ever scrap and replace anything. Thus we get goose bumps even though we no longer have fir, a woman's uterus is designed for species walking on all fours, and so on.
