Ethical dilemma: Who deserves your credence? - Alex Worsnip
Puzzle through the ethical dilemma of a spouse accused of murder and decide: do you believe your spouse or the evidence? -- You’re sitting on the couch, when you hear a knock on the door. The police have arrived to arrest your spouse— for murder. This accusation comes as a total shock, but their fingerprints were found on the murder weapon. Your spouse insists they’re innocent. Should you believe your spouse, even though the evidence against them looks damning? Alex Worsnip takes a look at this classic ethical dilemma. Lesson by Alex Worsnip, directed by Emily Howells and Aaron Brady. This video was produced in collaboration with the Parr Center for Ethics, housed within the renowned Philosophy Department at the University of North Carolina at Chapel Hill. The Parr Center is committed to integrating abstract work in ethical theory with the informed discussion of practical ethical issues, and prides itself on the development of innovative and inclusive approaches to moral and civic education.

Claws vs. nails - Matthew Borths
Discover the evolutionary purpose of nails, and explore the theories of why they evolved from claws over 55 million years ago. -- Consider the claw. Frequently found on animals around the world, it’s one of nature’s most versatile tools. Bears use claws for digging as well as defense. An eagle’s needle-like talons can pierce the skulls of their prey. Even the ancestors of primates used to wield these impressive appendages, until their claws evolved into nails. So what caused this adaptation? Matthew Borths investigates. Lesson by Matthew Borths, directed by Augenblick Studios.

What do all languages have in common? - Cameron Morin
Dig into Noam Chomsky’s theory of universal grammar and decide: are there universal grammar rules and are they hardwired into our brains? -- Language is endlessly variable. Each of us can come up with an infinite number of sentences in our native language, and we’re able to do so from an early age— almost as soon as we start to communicate in sentences. How is this possible? In the early 1950s, Noam Chomsky proposed a theory that the key to this versatility was grammar. Cameron Morin details Chomsky's theory of universal grammar.

View full lesson: http://ed.ted.com/lessons/mysteries-of-vernacular-lady-jessica-oreck-and-rachael-teel Why do we call women ladies?

The surprising path to mastering something - David Epstein
Are we building skills the wrong way? Explore how having a wide range of experience can be better than early specialization. -- There’s a common idea that it takes 10,000 hours of practice to become great at something. From an early age, we are encouraged to choose our path, focus specifically, and start racking up those hours. But, what if these head starts aren’t helping us the way we think they do? What if there’s a better way to excel? David Epstein shares how a different approach could set us up for greater success. Directed by Avi Ofer.

Why Libya's revolution didn't succeed -- and what might - Zahra' Langhi
In Libya, Zahra' Langhi was part of the "days of rage" movement that helped topple the dictator Gaddafi. But -- then what? In their first elections, Libyans tried an innovative slate of candidates, the "zipper ballot," that ensured equal representation from men and women of both sides. Yet the same gridlocked politics of dominance and exclusion won out. What Libya needs now, Langhi suggests, is collaboration, not competition; compassion, not rage. Talk by Zahra' Langhi.
