This activity explores the concepts and research presented in the short film Out of the Ashes: Dawn of the Age of Mammals, which explores how life on Earth recovered after a major asteroid impact.
This activity explores images of stickleback fish, some with spines and some without spines, which serve as phenomena for learning about gene regulation and natural selection.
This film explores how life recovered after an asteroid wiped out the dinosaurs and how those events shaped the diversity of plants and mammals on Earth today.
This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
This model shows the skull of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the skeleton of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the pectoral fin bones of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the pelvis of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the humerus bone of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This activity guides the analysis of a published scientific figure from a study that used footprints formed millions of years ago to estimate the heights of early human ancestors.
