The mountains barred the western rains from reaching the interior of the continent, which consequently turned into a dry and hot savanna.  Scientists think that these geological changes triggered the changes in evolution.	1	{Geology:::Plate Tectonics and Earthquakes}

Planet of Life: Apes to Man, Part 2	The site where the ancient fossilized skeleton of "Lucy" was found yields very little information about the ecosystem of the time.  Scientists have found pollen in the volcanic rock near her skeleton.  A scientist in France is hoping that an analysis of the pollen will provide some clues about "Lucy's" habitat.  The discovery of rice pollen suggests that "Lucy" did venture out of the forest to the savanna.	1	{Animals:::Mammals}

Planet of Life: Apes to Man, Part 2	As the forests faded, the apes had to adapt to getting their food in different ways.  Some believe that this may be what caused hominids to first start walking upright.  Walking upright was a more efficient means of locomotion.  Many experts consider bipedalism to be a major dividing line between man and apes.	1	{Animals:::Mammals}

Host explains how prehistoric leopards would often drag their prey up into the trees to eat it there and protect it from other predators.  In a cave full of the fossilized remains of these prey, scientists have discovered another skeleton of an early man: "Robust Almost-Man."  In the back of the skull are two perfect holes, which match the fangs of leopards from that period.	1	{Animals:::Mammals}

bact002003	Our Overuse of Antibiotics	Video	Discovery Communications, Inc.	Understanding: Bacteria, Part 2	Children today seem to be building up resistance to the range of available antibiotics.  Many children who suffer from ear infections are having to undergo more than one round of antibiotics.  Another problem is that people overuse antibiotics, even to cure colds -- which are caused by viruses, and cannot be treated by antibiotics.  Antibiotics are also fed to animals and sprayed on fruits and vegetables.  Many feel that this is excessive and will create a problem for us in the very near future.	1	{Animals:::Microorganisms}

The Ultimate Guide: Elephants	Elephants tend to live in hot places and have developed a number of mechanisms that help them keep cool.  One of them is their wrinkled skin.  Another is the habit of wallowing in mud.	1	{Animals:::Mammals}
elph001007	How Elephants Keep Cool in the Heat, Part II	Video	Discovery Communications, Inc.	The Ultimate Guide: Elephants	The best mechanism that elephants have to help them keep cool are their ears -- they act like the radiator of a car in allowing elephants to use the blood vessels in the ears to cool the blood.  The process is speeded up by flapping the ears.  All the blood in an elephant can be pumped through the ears (100 gallons) in 20 minutes.  Because African elephants are in greater sun, they have developed larger ears.	1	{Animals:::Mammals}

Planet of Life: Evolution's Next Step, Part 1	Dr. Paul Martin, Geologist, believes that hunting almost completely wiped out the mammals in North America, including the bison and the sabre-toothed tiger.  As humans pressed on to South America, they left drawings on cave walls.  The decline of animal resources required that the humans find other sources for their food and undertake agricultural endeavors.	1	{Animals:::Mammals}
evol001008	What Caused Early Humans To Form Villages?	Video	Discovery Communications, Inc.	Planet of Life: Evolution's Next Step, Part 1	Climate was one of the reasons that these permanent settlements came to be; the warmer temperatures allowed previously nomadic people to settle down.  Video includes a graphic showing the landscape transformed by warmer temperature and more water and of early shelters built by early man.  The change from nomadic tribes to settle villages required that they develop a form of social order and new crafts.	1	{Meteorology:::Weather}
evol001009	The Ending of the Ice Age Brings New Weather Patterns	Video	Discovery Communications, Inc.	Planet of Life: Evolution's Next Step, Part 1	Dramatic changes were also afoot in the western hemisphere.  Glaciers were retreating as temperatures rose.  As the glaciers melted, rivulets became torrential rivers.  The flow created a huge lake in the middle of the continent that was only held back by glaciers.  When the glaciers gave away, there were floods of epic proportion.  Some scientist believe that this single event triggered a shift in global weather patterns.	1	{Meteorology:::Weather}
evol001010	Evidence of the Ice Age in Greenland's Ice	Video	Discovery Communications, Inc.	Planet of Life: Evolution's Next Step, Part 1	Evidence of the climatic changes on Earth during this period still exist in the glaciers to our north.  In Greenland, they are studying the ice to learn about the history of the Earth's transitions.  They have found ice that is 10,000 years old.  The ice is layered, and the layers correspond to years in the same way that a tree trunk tells the age of the tree.  The ice gives evidence of a very cold period about 10,000 years ago, when the Ice Age is thought to have occurred.	1	{Geology:::Earth}

Planet of Life: Evolution's Next Step, Part 1	In the fertile crescent in Africa, where man first settled, the grasslands and forests disappeared, creating drastic food shortages.  This led to the beginning of farming and agricultural societies as they tried to solve the food crisis.  Researchers have collected over 150 different varieties of plant seeds as they have excavated the ruins in the fertile crescent.  The seeds were for hardy wheat and legumes.	1	{Meteorology:::Weather}

evol002002	The Domestication of Wheat	Video	Discovery Communications, Inc.	Planet of Life: Evolution's Next Step, Part 2	By cultivating plants, humans gained more control over their food supply.  This simple act revolutionized the way in which societies developed.  A scientist studying how wild wheat becomes domesticated notes that once domesticated, wheat loses its ability to reproduce by itself -- it requires farmers to harvest and then plant the seeds.  Wild wheat retains the ability to protect its seeds, which eventually are planted once the plant falls to the ground.	1	{Plants:::Herbaceous}
