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.
