The emergence of the domestic dog lineage occurred soon after the human expansion out of Africa 50,000 years ago. Now we have genetics to trace the evolution of man’s best friend.

I'm disturbed by tenured faculty on here behaving like high school bullies. I ask them to look up ad hominem and recognize that what Mamdani did was atrocious and newsworthy. Why are we defending an uber-privileged applicant whose father was faculty at the Ivy League university he was applying to?
