Perhaps because I just got a new dog, this story attracted me: dogs may not have come to the Americas until 10,000 years ago, leading to the speculation that:
"The new finding suggests that dogs came to the Americas with a second wave of human migration, thousands of years after people first traveled to the Americas from Asia."
It's based on DNA studies of ancient American remains of dogs. Sounds like an early result to me. Come back in ten years to see if it holds up!
By the way, the pre-Columbian people did not have cats.
The path to getting a bobcat to follow commands,
frequently involves getting scratched-up hands.
