Anton Petrov on the Bio-evolutionary Anthropocene Hypothesis

It's a thing. Human cultures profoundly affect evolution of animals and plants. See this 2018 paper The Biological Anthropocene: rethinking novelty organisms, interactions, and evolution by Pablo J. F. Pena Rodrigues and Catarina Fonseca Lira.

See Ancient dog mitogenomes support the dual dispersal of dogs and agriculture into South America (this happened 7000 to 5000 years ago) this is a very detailed and complex genetic study.

I have often wondered about the belief that people in San José de Uchupiamonas have about dogs: that you mustn't let them chew bones of animals you've hunted or otherwise you won't be able to kill anything. It's OK to give them bones of domesticated animals like chickens or pigs though. According to the above paper the European dogs brought by the Spanish in the sixteenth century overwhelmed the earlier dogs. "From the sixteenth century onwards, the introduction of dogs by the European settlers impacted the population of pre-contact dogs, whose genomic signature is now almost completely diluted in European dogs ancestry. One notable exception are Chihuahuas that still carry, for some individuals, a pre-contact maternal line, providing evidence of their Mexican origin."
