Students explore the evolutionary history of cavefishes while learning how to interpret phylogenies. This real world example intrigues students. The worksheet provides information about phylogenies, including how they are constructed and interpreted as well as the general vocabulary associated with phylogenies.
The two page worksheet requires students to label features of a phylogeny, determine relatedness of species, identify traits as ancestral or derived, and apply vocabulary.
Great activity to use when talking about evolution, relatedness, speciation, or just for fun!
Perfect for sixth, seventh, eighth, ninth, tenth, eleventh, and twelfth grades.
