I’m an anthropologist who studies human-animal interactions, a field known as anthrozoology. I want to better understand the behavior of pet parenting by people from the perspective of evolutionary science. After all, cultural norms and evolutionary biology both suggest people should focus on raising their own children, not animals of a completely different species.
The current moment is unique in human history. Many societies, including that in the United States, are experiencing major changes in how people live, work and socialize.
It is literally in our DNA and our ancestral history to help care for offspring who are not our own. Anthropologists and biologists call this trait alloparenting. It is an evolutionary adaptation that helped human beings who cooperatively raised children survive. For early humans, this ancient environment was likely made up of small, foraging societies in which some people exchanged child care for food and other resources.

I propose that it is this evolutionary history that explains pet parenting. If people evolved to alloparent, and our environment is now making caring for children more difficult or less appealing to some, it makes sense for people to alloparent other species entering their homes.
