Evolution is most definitely nonrandom.

Lots of random and semirandom changes are introduced via mutation and gene swapping.
The individuals with positive changes get copied because they survive to breed.
The individuals with detrimental changes get killed off.

If you take a random distribution of new individuals similar to your current population and then kill off the lowest 90%, the average goes up.

We are the top 0.0000...001% of our class, because we passed the survival exam and its brutal, bell curved marking scheme.
