No. Natural selection works in all populations. However, new alleles spread more slowly in large populations; the large size has a stabilizing effect. So one should expect large populations to change more slowly than smaller populations.
Increase in size and complexity
It is when there are too many people living on the same place so the supplies like food and other things wont be sufficient enough to maintain the populations size.
