Why don't we all have brown eyes by now? As we know from school education the gene that make us have brown eyes is dominent over green and blue. Surely after this amount of generations since we evolved we would have practically eliminated blue and green eyes. And further more if we evolved from apes why do we even have blue and green eyes, apes only have brown eyes?

This seems very likely. In 1999, a geneticist studied this phenomena very closely. He observed a family where both the mother and the father (P generation) had blond, and four children. The three children inherited the blond hair, except the youngest who inherited the red hair.
This phenomena isn't explained in Mendel's laws of inheritance. He only mentioned that two alleles seperate during gamete formation and t hen combine.
Very strange.
