This research profile follows paleoanthropologist Jackson Njau as he investigates ancient predators, like crocodiles and large cats, in an effort to understand how these organisms shaped the evolution of our human ancestors.
Cicadas spend years underground and come out once in a blue moon for a frenzy of activity. But certain broods come out like clockwork every 13 or 17 years. In this Science Update, you'll hear what's so special about these numbers.
The goal of this activity is to give students the opportunity to think like a scientist, making hypotheses, doing experiments, making observations, and analyzing data. Students are encouraged to construct and conduct their own experiments with ecosystems comprising grass, rabbits, and up to two predator species: hawks and foxes.

Students perform an activity similar to the childhood “telephone” game in which each communication step represents a biological process related to the passage of DNA from one cell to another. This game tangibly illustrates how DNA mutations can happen over several cell generations and the effects the mutations can have on the proteins that cells need to produce. Next, students use the results from the “telephone” game (normal, substitution, deletion or insertion) to test how the mutation affects the survivability of an organism in the wild. Through simple enactments, students act as “predators” and “eat” (remove) the organism from the environment, demonstrating natural selection based on mutation.
Sharks have inhabited the oceans for more than 400 million years. Join shark expert Jeffrey Graham as he describes the adaptations that have allowed these magnificent creatures to thrive over the millennia. Learn how shark biologists study shark physiology, life history, and behavior for insight into what allows these animals to rank among the worldŐs most efficient predators. (57 minutes)
David Attenborough looks at Í˘__ëńlife in the treesÍ˘__ë_ ˘: examining how species have evolved to cope with arboreal living. You will learn how lemurs, anteaters, bears and many others have developed different methods to help movement and survival.
