I love my dog. Now please address the question of natural selection as to the evolution of love which you have for your wife. Was love selected for and therefore has no meaning other than a biochemical expression of your encoded DNA. Or does it have a different and deeper cauality and therefore meaning. If it is biochemical only, please do not tell your wife, as it might break her heart. If it is more than biochemical, please explain its origin and reason of expression. Remember the cattle grazing on the side of a mountain do not genetically grow shorter legs on the left than the right. It is not mediated per environment.
I would ask you politely to go back to my posts and question whether you have actually responded to them. Here's a clue. In every one of your responses you have ignored what I said and have misquoted me in ways that make your posts nonresponsive. I never asked whether you loved your dog, or anything like that.
Someone put it all into song once:
Nuclear fusion makes stars to shine.
Tropisms ma-ake the i-ivy twine.
Ray-ayleigh scattering makes skies so blue.
Testicular hormones are why I love youuu!
