Discussing Extinction (02:32)
The Pyrenean Ibex is the only species to have gone extinct—twice. Dara O'Briain introduces expert panelists on Science Club and outlines the topic of species loss.
Understanding Extinction (01:18)
Panelists show a trilobite fossil and explain the natural process of species loss.
Historical View of Extinction (03:50)
Learn how Biblical beliefs developed into an understanding of geological time through fossil evidence and evolutionary theory. Scientists discovered periods of mass extinction, including one occurring now.
Frog Killer (05:34)
Up to 99% of species have been lost during mass extinctions. Learn how the African clawed toad carries a fungus responsible for 40% of amphibians becoming endangered.
Habitat Loss (02:02)
Learn how increased global meat demand is responsible for species extinctions.
Lab Grown Beef (05:45)
At the University of Maastrict, researchers grow bovine muscle cells from stem cells. Learn how the process works and witness a scientific taste test.
Food Science Breakthrough (01:53)
Although in the proof of concept stage, scientists hope that lab cultured beef can be scaled up for industrial meat production.
Species Saving Ethics (01:58)
Alok Jha investigates whether Giant Pandas are worth the costs of keeping them alive. Learn about the endangered species' reproductive and eating habits.
Conservation Efficiency (01:27)
The London Zoological Society is attempting to prioritize endangered species by evolutionary distinction to maintain a wide gene pool.
Bee Decline (02:18)
Learn the importance of pollinators in food production and ecosystem function. Species extinction would have devastating effects, compared to pandas—but the conservation "poster child" helps spread awareness.
Conservation Debate (02:49)
Panelists argue for saving endangered species with key ecosystem functions, rather than charismatic mega fauna.
Human Extinction Threat (02:37)
Mark Steel visits Berlin to learn about an asteroid that could potentially hit Earth in 2036.
Near Earth Object Shield (02:27)
A physicist uses a billiards table to illustrate how space technology can deflect an asteroid from striking earth.
Reconstructing a Comet (05:06)
Learn the difference between asteroids, meteorites and comets. A scientist recreates a comet in the studio using carbon, dry ice, amino acids, and ethanol.
Genetic Arc Project (02:29)
Dr. Helen Czerski reports from New Orleans, where endangered species DNA is preserved and used to create embryos through IVF fertilization.
Resurrecting Extinct Species (03:23)
Learn how an African blackfooted wildcat embryo was implanted in a domestic cat, through interspecies surrogacy. Cloning by inserting DNA into embryos of other species is another method under study.
Resurrecting a Wooly Mammoth (01:43)
Panelists discuss the possibility of using DNA to bring extinct species back to life. O'Briain thanks guests on the show.
