Fancy a trip into prehistoric times?
Go back in time with Cosmos: A Space Time Odyssey (30,000 years to be exact)
Let’s go back with Cosmos: A Space Time Odyssey, across 30,000 years to a time when our ancestors lived in the endless winter of the last ice age. All the plants and all the animals were wild. Our ancestors were wanderers living in small bands, they slept beneath the stars. The sky was their storybook, calendar, an instruction manual for living. It told them when the bitter colds would come, when the wild grains would ripen, when the herds of caribou and bison would be on the move. They hunted and gathered everything they ate and wore.
Life is transformation. Artificial selection turned the wild wolf into the tame dogs, we keep as pets today. This episode of Cosmos takes us back to our roots and takes an in-depth look at how natural selection works, as well as artificial selection.
If artificial selection can work such profound changes in only 10,000 or 15,000 years, what can natural selection do operating over billions of years? The answer is all the beauty and diversity of life. But how does it work?
