Explore key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity with this engaging interactive.
Compare and contrast the anatomy of the heart and the circulatory systems of major vertebrate groups and gain insights into their evolution.
Explore the phases, checkpoints, and protein regulators of the cell cycle in this highly interactive Click and Learn and find out how mutated versions of these proteins can lead to the development of cancer.
This Click and Learn describes how understanding the structure of the BCR-ABL kinase led to the development of an effective treatment for chronic myeloid leukemia.
A highly visual interactive timeline for exploring the history of Gorongosa National Park, from its beginnings as a hunting reserve and decline in the wake of a civil war, to its return to being one of the world’s foremost wildlife treasures and case studies in conservation biology.
This interactive map of Gorongosa National Park allows users to explore different features of the park, including key components of the conservation strategy.
The fossils of transitional creatures were key evidence for Darwin’s evolutionary theory, but none had been found when he published On the Origin of Species. Now, there are many examples of such fossils, which clearly show that big evolutionary leaps consist of many smaller steps.
This interactive explores different anatomical features of the human body and what they reveal about the evolutionary history we share with other organisms, including earlier, long-extinct species.
Finches discriminate between members of their own species and those of a closely related species based on song and appearance.
Explore the changes in oxygen levels throughout Earth’s history and discover their impact on life.
Earth's climate is a complex system controlled by many factors. This Click and Learn will examine the two most important factors: solar radiation and the composition of Earth's atmosphere.
The record of life on Earth stretches over 3 billion years. Deep time and Earth history are keys to understanding the present.
Paleoanthropology provides an excellent example of the scientific process at work.
Lactase persistence results from a mutation that changes how transcription factors interact, thereby affecting gene expression.
Lactose tolerance, sickle cell anemia, and bitter taste perception are three examples of recently evolved human traits.
Comparing features of a 4.4-million-year-old fossil skeleton to those of human and chimpanzee skeletons sheds light on our evolutionary history.
This Click and Learn explains how DNA sequences can be used to generate such trees, and how to interpret them.
Answer interactive questions to explore the logic of the Virochip microarray design, particularly how evolutionary relationships can be used to detect new viruses.
Learn the principles of how DNA is sequenced and assembled into whole genomes using the Sanger method, shotgun sequencing, or ultra-deep sequencing.
Learn about the nature of vector-borne diseases, and the life cycle of the dengue vector mosquito.
West Nile virus infects mosquitoes, birds, and people—with very different consequences.
Understand how quorum sensing works by reasoning through experiments involving genetically-engineered bioluminescent bacteria.
Explore the biology of the symbiotic relationship between the Hawaiian Bobtail squid and bioluminescent bacteria Vibrio fischeri.
Explore principles of taxonomy by sorting seashells according to their morphological characteristics and constructing an evolutionary tree.
