So, at this point, we've establish the following:

Evolution may or may not be the sole cause of human development.

The defenses to this so far are :

1) Lots of scientists think it absolutely must work this way, therefore it can work no other.

2) We've see nothing that suggests otherwise, so therefore nothing else can exist (evolution-believer's version of an argument from ignorance).

If someone responds with something of any merit I'll respond, but we're spinning wheels at this point due to team evolution being incapable of admitting they are not omniscient.
