This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This video describes the research of Dr. Manuel Leal, who is studying territorial lizards to understand how they navigate the dense forests of Puerto Rico to find their way to their home trees.

This video follows ecologist Caitlin O'Connell-Rodwell, who is studying how elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground.

This video follows scientists working in Bangladesh as they test fruit bat populations to determine whether they are infected with Nipah virus, a potentially deadly human pathogen.

This video introduces the concept of niche partitioning with examples drawn from the African savanna.

This video follows scientists as they uncover the ways in which moth species in Gorongosa National Park use ultrasound to avoid being eaten by bats.

This animation shows how termite mounds can increase the productivity of African savanna ecosystems.

This film explores what our hair, teeth, and hearing reveal about our evolution from ancient reptilian ancestors.

This film explores how the genetic and anatomical legacy of a fish can be seen today in the human body.

This video shows the reactions of first-grade students to a replica of a Tiktaalik fossil.

This animation shows how a single species can give rise to many different species with distinct traits, using anole lizards as an example.

This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.
