Spoken Here: Travels Among Threatened LanguagesSpoken Here: Travels Among Threatened Languages

Half the world's languages are threatened with extinction over the next century, as English and the rest of the world's top twenty languages drive all before them. What ways of looking at the world will die along with them, what cultural riches, what experiences, histories and memories? And how does it feel to be one of the last remaining speakers of a language that is on its way to extinction? What chance is there of saving any of these languages? Is it feasible in the long term or even worthwhile?

Discovery School - 100 Greatest Discoveries - Evolution

 

1. K-T Asteroid Theory of Dinosaur Extinction (1980)
Walter Alvarez postulates that high levels of iridium found in rock core samples around the world provide evidence that an asteroid impact caused the extinction of dinosaurs. Iridium, a common mineral found in asteroids, was discovered in the clay layer at what is known as the K-T boundary. This layer, at 65 million years, lies between the rocks of the Cretaceous and the Tertiary periods and coincides with the mass extinction of dinosaurs.

2. First Dinosaur Fossils Identified (1820s – 1840s)
