  • A painting depicts scientists comparing Piltdown Man's remains to other species. Charles Dawson and Sir Arthur Smith Woodward are seen standing together.

    The myth of the missing link is persistent and argues that there must be a specimen that partly resembles an ape but also partly resembles a modern human. However, the reality is that there is no missing link in the human lineage because that’s not how evolution works. Part of the "Eons" series.

  • Flock of large birds landing on the shore and in the water. Caption: the wildlife simply adapts to the new conditions.

    This program from the acclaimed PBS Nature series, "Forces of the Wild," looks at man's constant attempt to adapt the Earth to his own needs without concern of the consequences. Earth is a self-regulating organism full of forces impossible to control. Water is one force, creating life where there is none and destroying life when it can't be tamed. Narrated by James Earl Jones.

  • A corn mixture travels in a conveyor belt. Caption: Starch and gluten are separated from the germ.

    Corn is king. It can be found in other foods, in the ink for pens, and in gas for cars. Indeed, it's one of the most versatile substances on the planet. Today, it is a very different product than the one that once grew wild across North America. In this episode, Dr. Joe Schwarcz traces the evolution of corn. Part of the "Science to Go With Dr. Joe Schwarcz" series.

  • A herd of elephants. Caption: Some elephant populations seem to be missing their tusks.

    Working in Gorongosa National Park, Mozambique, Dr. Joyce Poole and colleagues make a striking observation: many female elephants lack tusks. Elephant tusks are important for obtaining food and water, and essential to male elephants for competing for mates. There is a strong natural selection for having tusks; however, Dr. Poole has discovered the proportion of tuskless elephants has increased in some populations. She explains possible reasons for the increase in the number of elephants lacking tusks.

  • Monarch butterflies on foliage. Caption: In monarchs, they study a parasite.

    There's a most unusual gym in ecologist Sonia Altizer’s lab at the University of Georgia. The athletes are monarch butterflies, and their workouts are carefully monitored to determine how parasites impact their flight performance. With support from the National Science Foundation, Altizer and her team study how animal behavior, including long distance migration, affects the spread and evolution of infectious disease. Part of the National Science Foundation Series “Science Nation.”

  • Human holding a small puppy and looking into its eyes. Caption: According to genetics,

    New scientific evidence suggests that some wolves evolved into dogs by domesticating themselves, and not by humans taming them. Features evidence that dogs have traveled and been buried with humans since prehistory, adapting to every climate and evolving into many subspecies or types of the same dog species. Human cultures might not have evolved as they did without the help of the dog, our most cherished and probably first domestic animal companion.

  • Closeup of a huge pile of kernels of dried corn. Caption: making corn the number-one crop by weight.

    The evolution of the uses of corn coincides with some significant historical events. Throughout history, it has been a staple in the human diet, but in the 1950’s, it became the main ingredient in the meat industry. Farmers used corn to shrink the growth periods of cattle to meet the demand of the consumer. Corn syrup was born from the Cuban Embargo. Today, genetically engineered corn is seen in nonfood products.
