Is it puzzling that humans have pets?
Pets have long posed an evolutionary enigma for researchers. We have to feed them, house them, cut their toenails, clean their teeth and scratch behind their ears. A relationship like that could be considered a poor return on investment.
“Lavishing resources on members of other species we have no evolutionary stake in seems to make no evolutionary sense,” said Hal Herzog, a psychologist and animal expert at Western Carolina University who was not involved with the research. Yet many cultures across the world have pets and cherish them dearly.
Does it really seem to make no evolutionary sense?
The many practical reasons for having pets (rodent control, guarding, protection, assistance in hunting and so on) aside, doesn’t well-being/happiness make evolutionary sense?
Maybe this is just journalistic over-simplification of what makes evolutionary sense.
“There are theories that pet-keeping began either because animals were useful for tasks like hunting and protection or because humans have a natural tendency to care for and bond with other living beings,” said Zoë Goldsborough, a behavioral ecologist at the Max Planck Institute of Animal Behavior who was not involved with the research.
Or both, ffs. Your dog can help with hunting and guard the pack and be a companion.
Maybe this is just drastically oversimplified for a broad audience, but it seems simplified to the point of absurdity.
