This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).
In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO2 starting in 1958.
This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.
This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.
Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.
A number of interactive questions are embedded within the short film The Biology of Skin Color, which explores the hypothesis that the variations in skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
A number of questions are embedded within the short film Great Transitions: The Origin of Humans. The film explores the major fossil finds from Africa that provide insights into the evolution of modern humans from a common ancestor we share with other primates.
