"CENSORED" not to get an infraction.
Now on topic:
I'm. Not. Speaking. About. The. Chance. Of. "Life appeared on Earth rather than on Mars".
I'm speaking about the chance of a single CELL (living, functioning, yet very simple ORGANISM) to appear ON EARTH, out of EARTH's materials, by a supposed SEQUENCE of chemical reactions that would END UP as that poor little cell!
Simplifying again:
You need a sequence of a million of molecules arranged in the RIGHT way, through multitude of reactions.
All I get is, "it just happened".
Well, DUH!!!
Antilogic
NO!
I'm asking of the way they changed from NON flying reptiles into FLYING birds.
1. The wings are a totally NEW ability which the reptiles DID NOT "know" how to use. ("Behavior")
2. Until there were (fully working) WINGS, the FEATHERS were just "sitting there", disturbing the mobility. ("Quantum leap" vs "Gradual evolution"). Also, they needed newly formed MUSCLES to actually fly.
1+2. I'm asking for a clear source on how this could happen GRADUALLY, over thousands of years.
LINKS ONLY, please.

MUSCLES!!!
Birds have VERY different muscles that let them actually fly.
Moderator Action: self-censoring won't help not getting infractions for trolling/flaming. Only leaving out the parts in question will help that. Furthermore, more civility in this post is needed
