I do sometimes accuse people of ignorance, but that is not intended to be an insult. I'm ignorant of lots of things. Ignorance is something that can be remedied by education.
Richard DawkinsThere is economics in biology, nothing is free, everything has to be paid for, there are costs as well as benefits to everything in life, for example, there was never sufficient natural selection pressure to develop better eyes, individuals could earn other things like smiley smiles rather than waste energy & time on better eyes.
Richard DawkinsSuppose that there's a gene that makes you gay if you were bottle-fed but that has some completely different effect if you were breast-fed. So in the days before bottles were invented that gene would not have manifested itself as gay behavior, but now that bottles are common it can do so.
