A new species of beetle is discovered. If you were a cladist, what steps might you take to classify this
beetle? How might this approach be different if you were a pheneticist? What will be an ideal response?
Cladists would classifies a new species of beetle by identifying most recent common ancestor by
identifying shared derived characters of known beetle species and comparing to the outgroup.
Pheneticsist would classify the new species of beetle by the amount of shared features with another
beetle species.
Concepts to Consider: Cladists study shared and ancestral characters and attempt to identify
outgroups; pheneticists use a numerical approach and quantify shared characteristics to determine
taxonomic classification.
