Biointeractive rock pocket mouse3/25/2023 ![]() No two lizard species living in the same habitat share the same type of dewlap, the flap of skin under their throats that male anoles display to attract females. ![]() ![]() What happens when lizards that belong to a particular ecomorph group are placed in a different habitat? In this module you will collect and analyze data from an experiment designed to answer that question. In this module, you will build a phylogenetic tree of anole species to study how the different species evolved. Analysis of the DNA sequences of certain genes reveals the evolutionary relationships among different anole species. In this module, you will take measurements of lizards from species belonging to four different ecomorph groups. Species of Caribbean anoles can be categorized into groups, called ecomorphs, according to their body characteristics (morphology) and the ecological niches they occupy. The lab includes four modules that cover different concepts in evolutionary biology, including adaptation, convergent evolution, phylogenetic analysis, reproductive isolation, and speciation. In this lab, students investigate how so many species of anoles evolved. The Caribbean is home to about 150 species of anole lizards. This class was created by the Howard Hugues Medical Institute (HHMI). This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.
