Modern humans thrived in the Americas for thousands of years before the first European colonists arrived, but how and when did they get there?What's more, did their arrival spell disaster for indigenous megafauna such as giant ground sloths and wooly mammoths, or was there another culprit behind the mass extinctions across North, Central & South America?In this episode, Tristan is joined by Professor David Meltzer, an archeologist from Southern Methodist University, to explore the nature of human migration into the Americas and how scientific developments now allow us to discover more about those very first Americans.Tickets to Tristan's talk 'London in the Roman World' with Professor Dominic Perring on July 4 are available here: https://shop.historyhit.com/product/london-in-the-roman-world/ Our GDPR privacy policy was updated on August 8, 2022.
