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.
Pheneticists 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.
