@ShaulaEvans Male bees (and wasps, and ants) are _haploid_ and do not have fathers. They are not just the only animals, but the only _eukaryotes_ to evolve reproduction that differs from the normal alternation of haploid/diploid generations. (Reproduction is usually very strongly evolutionarily conserved, for obvious reasons: if a mutation messes it up somehow, there's no chance for it to get sorted out again in future generations, because there won't _be_ any future generations.) So euphemising sex ed as "the birds and the bees" is unhelpful, as "the bees" are literally _the_ worst available model organism for human reproduction.
