So, in other words, "yes, humans breed selectively."Dizchu said:People reproduce with people that they find sexually attractive. It's not a conscious effort to breed the ideal humans. Well unless we're talking about royal families but I think most of us aren't in favour of inbreeding.SimpleFool said:Are you saying humans do not selectively reproduce themselves, but instead reproduce indiscriminately?
So, it's the dog-breeding environment, and not the ancestry of the dogs, that possibly leads to the outcome that certain breeds appear much more aggressive than others. Do I understand you correctly?If you mean genetically then no. If you mean in terms of environment then absolutely.I'm sorry; I've read your "response" twice now, and I'm not seeing a clear answer to my question - are you denying aggression may possibly be a heritable trait? Yes, or no, if you please.
And, a follow up: is it your position behavioral traits, generally speaking, are not heritable? Or is it just not the ones deemed "negative" from a social standpoint?
