The Doomsday Argument

Is human extinction inevitable and how will it all end? Will it be anthropogenic, the result of human action, or will it come from the good old-fashioned kind of extinction the earth knows too well. The Global Catastrophic Risks Survey, issued by Oxford University’s Future of Humanity Institute, placed our extinction before 2100 at 19 percent. Host Michael Stevens says that a simple explanation, known as The Doomsday Argument, can show that simple extinction soon is more probable. He explains in this episode of Vsauce.

Our Extinct Ancestors

Modern humans, or homo sapiens, are the only living species in their genus, but history teaches us that several other species of ancient humans have existed. Take the Denisovans, whose remains were found in a Siberian cave in 2008. Geneticists sequenced their genome and it was revealed they evolved from an unknown species with dark skin, brown eyes and brown hair, unlike their Neanderthal cousins. They are believed to have gone completely extinct. Hear about nine other mysterious extinct human species in this edition of Hybrid Librarian.

Human Extinction Inevitable

The Global Catastrophic Risks Survey says there’s a 19 percent probability that humans will become extinct by the year 2100. Host Michael Stevens asks, “Are humans going to go extinct soon? Will human extinction be anthropogenic, that is the result of human action, or will it be one of the good old-fashioned kinds of extinction Earth’s history knows pretty well?” Stevens digs deeper into the questions and gets some possible solutions in this stirring edition of Vsauce.
