It’s a law of nature that a male keeps as many females as he can service.
One guy gets the harem; everyone else gets the hand. Lions do with brute force what men do with money, extrapolate themselves and their line into the future, and create the world in their own image and likeness. This genetic selfishness also inadvertently strengthens the species. The strongest stud propagates the new generation. This is the ‘founder effect’: “I found her; you can’t have her.” Cloning would not only take all the fun out of it, but would weaken the species by separating it from the usual trials of natural selection. Love is finished when there is no forward movement, just up and down, in and out. Evolution appreciates motivation and inspiration, punctuated equilibrium.
