Connecting Concepts: Evolution/Species & Speciation 1: Discovering Species

Students look at 5 frog populations to decide whether they should be considered separate species using criteria of three of the species concepts: biological, morphological, and phylogenetic. Students will: 1) describe why species are continuous over time and space; 2) review definitions of three species concepts with strengths and weaknesses of each; 3) analyze traits to sort populations into species based on 3 species concepts; and 4) gain familiarity with: 3 species concepts, phylogenetic trees, and reproductive isolation.

Part one of three excellent interactive exercises that investigate the concept of speciation. Students are required to draw conclusions from information and data provided. Uses audible as well as visual effects. Very well organized and well written.
