Linnaean Taxonomy and Phylogenetics

Systematics is a tricky venture. Since the time of Aristotle, humans have been attempting to classify life on earth. In our modern scientific era, two primary modes of classification have been established: Linnaean Taxonomy and Phylogenetics. While both focused on classifying life, each model has different philosophies and different methods (grades versus clades).
Explain the philosophical and methodological differences between Linnaean Taxonomy and Phylogenetic classification. Be sure to include:
-The logic behind morphological grades
-The logic behind evolutionary clades
-The methods of building a phylogeny (this relates to cladistics)
-Potential problems with each classification scheme (we reviewed potential problems with each)
Remember, the details matter…
