To solve old problems, study new species

Nature is wonderfully abundant, diverse and mysterious- but biological research today tends to focus on only 7 species, including rats, chickens, fruit flies and us. We're studying an astonishingly narrow silver of life, says biologist Alejandro Sanchez Alvarado, and hoping it'll be enough to solve the oldest, most challenging problems, like cancer. Im this visually captivating talk, the author calls on us to interrogate the unknown and show us the remarkable discoveries that surface when we do.
