I watched a documentary on dogs that was cheerful until the last 5% when they mentioned modern day dog owners. The film speculated that dogs might be a considered like a parasite that infiltrates human families and causes them to stop breeding humans and instead only have dogs and cats. So if that’s the case, the evolution ends for us :)
I've heard this before. I think better term than parasite is an addictive drug since we created these types of pet dogs and indulge on them. I feel strongly the trend of dog ownership overtaking people having children, while real, is more so a result of modern economic realities regarding cost of housing and raising a child.
