Here's John Bachelor.

This is CBS I in the world. I'm John Bachelor. 66 million years ago, North America.

All North America divided into three parts.

Appalachia, the mid-continental

continental waterway, the interior waterway, and La Rameida.

This is the basis to begin a conversation about wild new world, a new book from Dan Flores,

the Abbe Hammond Professor Emeritus of Western History at the University of Montana and what Dan takes us is a time travel

from 66 million years ago and the asteroid that changed the direction of evolution to the period of time that we're

living in now called the Anthropocene, passing through a very important detail from 10,000 years ago called the Pleistocene.

This is the story of mammals chiefly, but also the story of one kind of mammal, that's us, the Homo sapiens, the hominids who arrived twice.

First from Eurasia, thousands of years ago, and then second from Eurasia again within our memory the so-called colonial

Eurasians. Dan, a very good evening to you. Thank you very much and it's a

pleasure to speak to you because of the sweep of your story and also what I learn is the philosophy of dealing with the wild animals of North America.

We begin with the dinosaur exit and the rebirth in the paleocene period.

The mammals that we speak of often now today, we speak of the reduction of the buffalo, we speak of the wolf, we speak of the

white-tailed deer. These were all developing during this long period of time from the exit of the dinosaur.

We're going to concentrate on the Pleistocene.

Were they all present during or after the Pleistocene, especially the ones that are familiar to us.

Good evening to you, Professor.

Thank you, John.
