Are our bodies adapted to be a hunter-gatherer on the Serengeti? The answer is complicated. Harvard biologist Daniel E. Lieberman says we're actually still evolving, and that cultural factors are as important in shaping humans as biological ones.

Evolutionary biologist Daniel E. Lieberman looks at how the human body has evolved over millions of years, and the conditions our bodies have not entirely adapted to, resulting in obesity and new but avoidable diseases like type 2 diabetes. Then, we’ll talk with director Kryzstztof Zanussi and two film restoration experts about a retrospective of Polish cinema curated by Martin Scorsese. Armistead Maupin discusses The Days of Anna Madrigal, the ninth installment in his Tales of the City series. And we’ll take look at the personal, physical and mental impact of McCarthyism on six New York City political activists.

Something happened to dolphins. Then it happened to humans. Both creatures had good-sized brains when, for reasons no one truly understands, dolphin brains suddenly got larger and larger, until — 15 million years ago — they stopped growing. Two million years ago it was our turn. Our brains went from the size of an orange to the size of a cantaloupe. Why the start? Why the stop? Who's next?

A recent Pew Research Center analysis finds that one-third of Americans reject the theory of evolution, believing that “humans and other living things have existed in their present form since the beginning of time.” Brooke speaks to Edward Caudill, author of Intelligently Designed: How Creationists Built the Campaign Against Evolution, who says that modern media has been a godsend for Creationists.

Journalist Diane Francis has a modest proposal: the U.S. and Canada should merge. She talks about what both countries could bring to the partnership. Plus: neuroscientist Sam Harris on lying; economist Emily Oster debunks pregnancy myths about what’s dangerous for a woman who is expecting; and a deep look at “mismatch diseases”; how to be a friend to a friend who is sick; and an urban monk talks about spirituality in the city.

Researchers at the Emory University School of Medicine recently released a study arguing that memories can be passed on through DNA. It’s the latest piece in a growing body of evidence for transgenerational epigenetic inheritance, and if it’s right, it could change the way we act in our everyday lives.

Scientists recently determined that Páramos, small, high-elevation ecosystems in the Andes, are the fastest evolving places on earth. Science writer Carl Zimmer explains what makes these tiny mountainous enclaves—and their giant daisy trees—so diverse.

Why did it take cells so long to link together and form tissues, organs, you, me, turtles, daisies? There was a couple of billion year pause before cells became multicellular. How come? With brilliant designer Paolo Ceric, we consider this puzzle of life.

This we know: that dinosaurs had babies. This we also know: that to have those babies, dinosaurs had sex. But here's what we don't know: with their size, their spikes, their scales, their genital equipment, how did they manage to do the deed? This doesn't prevent us from wondering.

A hundred years ago, a human-like skull and ape-like jaw were presented at a special meeting of the Geological Society in London. The so-called "Piltdown Man" became widely accepted as a crucial link in the human evolutionary chain; crucial, that is, until 1953, when the bones were exposed as a total hoax. In an interview from December of last year, Nova Senior Science Editor Evan Hadingham talks to Brooke about this tantalizing example of "scientific skullduggery."

At night, in the ocean, they look like little Broadway billboards with dazzling trills of rainbow colored light. They have eight little runways on their bodies for light display. What are they?
