Nature equips the African wild dog female with 16 ‘feeding stations’ for suckling a typical litter of 12 pups. In other words, for any given litter, nature typically provides a surplus of up to four teats. The strategy here is plain to see: (1) Make the typical wild dog litter relatively large in the face of inevitable attrition, but not so large as to overtax the females; (2) provide the typical wild dog female with four extra teats to accommodate the occasional oversized litter.
Now consider this: What if the wild dog’s natural enemies were to disappear overnight, en masse, and simultaneously, the typical wild dog female were to begin to have litters of 13 to 16 pups on a regular basis? What would happen to the local and global populations of wild dogs? Now turn to a different species, namely us (Homo Sapiens), and substitute ‘diseases’ for ‘predators,’ and ‘families,’ or ‘progeny,’ for ‘litters.’ What do you have before you? Alas, are there not already too many of our kind in the world, and, increasingly, too few ‘teats?’
