In Octopus Evolution, ecologist David Scheel describes the journey through the unique evolutionary history of octopuses, showing how these incredible creatures took a completely separate path from other life forms. In his class at Alaska Pacific University, he explains how, over half a billion years ago, octopuses and humans might have shared a common ancestor — but since then, octopuses developed their own specialized brain, heart, and eyes! This video is excerpted from BBC’s Natural World: The Octopus in My House, a remarkable series about a professor and the extraordinary relationship he develops with an octopus when he invites it to live in his home.
In Erosion and Evolution, geologist Iain Stewart explains that rivers and volcanoes have shaped the Earth in dramatic ways. Rivers sweep rock and debris with them as they head toward the ocean, preparing for new land to form downstream. Scientists have found the conditions that mimic those found when the Earth was young around volcanoes and hydrothermal vents. The changing amounts of ice on the planet also impact how modern man has adapted. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In Earth's Epic Comebacks, geologist Iain Stewart explores how Earth's history of disasters has shaped life and sparked evolution. From dinosaurs thriving after a mass extinction to bacteria surviving an ice age, Earth has always found a balance between stability and chaos. Now, humans are changing the climate and marking a new era called the Anthropocene. The question is: can we protect the planet that makes life so incredible? This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In Adaptations on the Kelp Forest and Ocean Floor, narrator Sir David Attenborough describes how bat rays, fish, and sea slugs have adapted to live in the kelp forest. Learn how animals have developed behavioral and physical adaptations to living on the sandy seafloor. This video is excerpted from BBC’s Blue Planet, a definitive documentary series diving into the mysterious depths of the sea to discover the natural history of the world’s oceans and the rarely seen marine life that reside there.
In The Underwater Adaptations of the Crab and the Octopus, narrator Sir David Attenborough explores how the crab and octopus survive. Learn how they have adapted to their environment, including hunting at night. This video is excerpted from BBC’s Blue Planet, a definitive documentary series diving into the mysterious depths of the sea to discover the natural history of the world’s oceans and the rarely seen marine life that reside there.
In Animal Adaptations Due to Receding Tides, narrator Sir David Attenborough explains how invertebrates in the mud are impacted by the receding tide, how flounder use the currents, and how ospreys hunt. Observe animal adaptations in the wading birds and the flounder. This video is excerpted from BBC’s Blue Planet, a definitive documentary series diving into the mysterious depths of the sea to discover the natural history of the world’s oceans and the rarely seen marine life that reside there.
In A Sea of Doom Beneath the Pacific, narrator Sir David Attenborough investigates the world of the deep ocean, where only a small amount of light shines and animals have evolved in interesting ways. This video is excerpted from BBC’s Blue Planet II, a natural history series that explores the world's oceans, the animals that live in them, and the threats they face, using modern filming techniques and equipment to capture previously unseen areas of the ocean.
In The Strange World of Troglobites, narrator Sir David Attenborough explores the fascinating world of troglobites, creatures that have adapted to living entirely in caves. These animals, including the Texas blind salamander and the Belizean white crab, are unique to their environments and have evolved specialized features to survive in total darkness. Lacking pigment and eyesight, they rely on other heightened senses to detect food. The cave angelfish uses microscopic hooks to cling to slippery surfaces, and the blind salamander can detect water movement to locate prey. This video is excerpted from BBC’s Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
In The Extravagant Displays of Birds-of-Paradise, narrator Sir David Attenborough showcases a few of the nearly 40 different kinds of birds-of-paradise on the island of New Guinea. Different birds-of-paradise live in different parts of New Guinea to avoid competing with one another. Male birds-of-paradise try to be extravagant to attract females. This video is excerpted from BBC's Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
In The Mandrill and Its Bright Red Nose, evolutionary biologist Ben Garrod learns all about the mandrill, focusing on the bright red nose of the species. Find out how this nose helps the mandrill communicate and why it is so important for survival. This video is excerpted from Secrets of Skin, a documentary series exploring the natural history of the body’s largest organ.
In Animals With Spines, evolutionary biologist Ben Garrod presents porcupines and how their quills have evolved as a defense mechanism. Learn how these animals, with their distinctive spines and quills, have adapted to survive in the wild as you discover how porcupines’ quills have evolved to detach and protect them from predators. This video is excerpted from Secrets of Skin, a documentary series exploring the natural history of the body’s largest organ.
In How Ice Provides a Reflective Shield on Earth, geologist Iain Stewart explains that ice is a unique substance. Because it floats and is reflective, it provides a reflective shield for the Earth and impacts how much energy is absorbed, which impacts the climate. The changing amounts of ice on the planet also impact how modern man has adapted. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
