I likewise pair this with an Amoeba Sisters video on speciation that I share on Edpuzzle with embedded questions. Speciation occurs across the range of spatial contexts summarized by the allopatric to sympatric continuum, but most speciation is associated with geographic separation. As I teach my unit on "Population Genetics", I assign a portion of these questions for homework each night. The process of splitting of genetically homogenous population into two or more populations that undergo genetic differentiation and eventual reproductive isolation is called speciation.
