Biological Evolution: Unity and Diversity

Biome in a Baggie | PBS LearningMediaThe distribution of plants and animals around the world corresponds closely to global patterns of temperature and rainfall. This is why two forests half a world away from each other will often have very similar organisms living in them. In this ZOOMSci video segment, a cast member of ZOOM creates a self-contained biome and explores evaporation, condensation, and precipitation.

NOVA | Photosynthesis | PBS LearningMediaIn this video from NOVA: Earth, explore the history of plant biology, from the earliest scientific hypotheses that plants ate dirt, to our present-day understanding of photosynthesis, the process by which plants use the Sun's energy to convert carbon dioxide and water into carbohydrates.

Illuminating Photosynthesis | PBS LearningMediaThis interactive feature from NOVA explores the process plants use to convert solar energy into chemical energy. The site points out that photosynthesis is responsible for feeding nearly all life forms on Earth and that the process generates, as a by-product, an element that is critically important to the survival of humans and most other animals: oxygen.

Beavers | PBS LearningMediaThe beaver is often referred to as nature's own engineer. This video focuses on the beaver's ability to transform its environment to suit itself. The beaver does so with an innate ability to construct dams—a feat that no creature apart from humans is able to achieve. This video is available in both English and Spanish audio, along with corresponding closed captions.

What Do Animals Eat? | PBS LearningMediaDo you eat like a horse? Or more like a bird? As you might expect, different animals eat different things. Some animals specialize in eating one particularly rich food source, while others eat whatever they can find. This video segment samples the diversity of feeding habits among some of the world's creatures.
