Adventures in Evolution: The Narrative of Tardigrada, Trundlers in Time.

Author information

Temple University, Biology Department, Institute of Genomics and Evolutionary Medicine.


A lesson plan on the phylum Tardigrada is presented in a storytelling workbook that introduces the evolutionary concepts of adaptive radiation, speciation, divergence, and "tree-thinking" through narrative, transitional art, contemplative coloring, and data searches, which can be enhanced with microscopy wet labs. Students gain insight into the invertebrate world of the highly adaptable, ubiquitous microorganisms known colloquially as "water bears," generating a microevolutionary and macroevolutionary perspective through a narrative that includes an introduction to the TimeTree database.
