Connecting Concepts: Evolution/Species & Speciation

This tutorial/simulation consists of three topics. In topic 1, 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. In topic 2, students will think about speciation events at several points along the phylogeny of the plant genus Fuchsia. Students decide whether vicariance, dispersal, or both are plausible explanations for... Show More

Well designed interactive site that helps students understand the mechanisms of speciation and the importance of being able to determine how many different species you are dealing with.

 

Use as part of a lab assignment both in class and online.

Interactives and animations that immediately confront student to perform active
thinking of the concepts presented. Original high quality content. The page for
