Natural selection is the non-random survival of random changes. At some point, humanity's ancestors started developing larger brains and survived because they adapted best to the environment.
Cool Spot - I meant sometime ago (months ago actually) to get back to your comment.
What evidence do they have, really, the statement that you make here:
"humanity's ancestors started developing larger brains and survived because they adapted best to the environment"
What is the observable evidence, that this took place and the statement you make is a statement of fact and not supposition?
Skulls are measured, readings taken, but there is no real
evidence from the science why and how we happen to be, and the intelligence we possess and that and to quote (passages cited - Acts 17:26 and Malachi 2:10):
... which seem to emphasize that the entire human race descended physically from Adam. It is not easy to reconcile such passages with the notion that Homo sapiens evolved from ape-like ancestors before Adam was personally selected for upgrading to Homo spiritualis

That is the very problem - the contradictions between what science supposes (based on supposition) to what God has declared = conflict.
