What Darwin Never Knew

(Program not available for streaming.) Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

Are We Still Evolving?

"There has been no biological change in humans in 40,000 or 50,000 years. Everything we call culture and civilization we've built with the same body and brain."
—Stephen Jay Gould

I was surprised when I read these words from one of the 20th century's leading thinkers on evolutionary theory. We hominids have been evolving for millions of years. Why would that have suddenly stopped? Isn't our kind, Homo sapiens, subject to the same forces of Darwinian natural selection as all other species?

Are We Still Evolving?

Whether humans are still evolving biologically depends—and doesn't—on which humans you ask.

Anatomy of the Battleship Yamato

In the mid-1930s, the Japanese Navy commissioned a ship called Yamato intended to be the greatest battleship in the world—with more powerful guns, advanced optics, and impenetrable armor. But by the time it entered service in 1941, aircraft carriers had begun to eclipse battleships in naval warfare, and Yamato fell victim to an air attack near the war's end. On this detailed blueprint, see what made the seemingly unsinkable ship vulnerable.

Explore a Pharaoh's Boat

In 1954, an Egyptian archeologist discovered an immense, beautifully crafted ship buried in pieces right beside the Great Pyramid of Khufu. Now fully reassembled, this extraordinary royal craft, one of the oldest planked vessels in the world, has revolutionized our understanding of ancient Egyptian shipbuilding and continues to astonish visitors to the Giza Plateau. In this slide show, take a close look at this 4,600-year-old ship of state.

Japan's WWII Midget Sub

During WWII, the Japanese Navy deployed hundreds of different sorts of submarines, but on December 7th, 1941, they debuted a particularly secret weapon—the Type A Ko-Hyoteki midget sub. Five furtively made their way toward Pearl Harbor to attack U.S. battleships. At a quarter the size of common fleet subs, the midgets were a technological marvel, far outperforming their western counterparts. Here, explore a model.

The Threat of Midget Subs Today

The United States currently faces enemy forces far different than those we faced on December 7, 1941. But a relatively untold story of the attack on Pearl Harbor holds a warning that is still relevant. Just as the Japanese employed stealthy small submarines to penetrate the harbor and attack the U.S. battle fleet from below, today enemies of the nation could use the modern equivalents of these so-called "midget" submarines to infiltrate our shores.

Where Is Punt?

You can almost imagine the Pharaoh Hatshepsut smirking from the other world. "We've got you, haven't we?" she might be saying, a twinkle in her bold eye. For Hatshepsut, along with all other ancient Egyptians, has left us a puzzle that we just can't seem to solve with any certainty. It's the mystery surrounding the location of Punt ("Poont"). Also known as God's Land, Punt was a faraway realm rich in incense, ebony, and gold with which the Egyptians traded for over a thousand years.
