Around the globe, unique and fascinating species face extinction from hunting and habitat destruction, which affects vulnerable animals in every kind of environment. Biologists, conservationists, wildlife preservation centers and zoological parks work to breed and shelter rare and critically endangered animals when and where they can, but many species are down to the last few individuals and face an increasingly uncertain future. For some, however, the future is all too clear. Lonesome George, a Pinta Island tortoise from the Galapagos Islands, is the very last of his kind.

NOVA visits a tribe of Ecuadoran Indians who still maintain traditions that date back to the Stone Age—thirty years after their first contact with Western Civilization.

Broadcast (2007) NATURE's two-part special DOGS THAT CHANGED THE WORLD tells the epic story of the wolf's evolution, how "man's best friend" changed human society and we in turn have radically transformed dogs. From the tiniest Chihuahua to the powerful and massive English Mastiff, modern domesticated dogs come in a bewildering array of shapes and sizes, with an equally diverse range of temperaments and behaviors. And yet, according to genetics, all dogs evolved from the savage and wild wolf-in a transformation that occurred just 15,000 years ago. (www.youtube.com)

Broadcast (2002) The best way to find food is to go out and hunt for it. But to hunt, you need to be able to move forward. And to move forward, you usually need a head with paired sense organs to know where you are going attached to a symmetrical body to get you there. Scientists believe that a flatworm like animal was the first creature to develop a head, brain, paired senses and a tail, the first to move forward and thus the first to hunt for food and mates. This breakthrough in bilateral design was enormous.

Broadcast (2002) As we go through our lives driving cars, exploring the Internet, studying the world around us it is hard to imagine that we're related to Earth's other animals. It's even a stretch to see what connects us with the rest of the chordates, a group of about 50,000 species including the vertebrates like fish, amphibians, reptiles and birds, mammals and ourselves. But indeed, all chordates, from the worm-like amphioxus to Homo sapiens have three common features.

Broadcast (2002) For the first time ever, scientists believe they have gathered substantial evidence that points to a single animal group of creatures that gave rise to all animals, including humans. Researchers such as Cristina Diaz and Mitch Sogin think that the most likely candidate for this "Animal Eve" is a group of creatures that still exist: the sponges. Sponges, members of the phylum Porifera, are considered the oldest living animal phylum. The name Porifera means "pore bearer" in Latin. Sponges are the only animals that if broken down to the level of their cells can miraculously reassemble themselves. These seemingly inanimate creatures are also fantastic pumps, filtering tons of water to harvest a few ounces of food. (www.youtube.com)
