Linnaean Taxonomy and Phylogenetics Essay Assignment
I’m working on a biology multi-part question and need an explanation and answer to help me learn.
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)
Attach a screenshot here of your completion of the NOVA Labs evolution mission 1
In the “deep tree” part of the NOVA lab website chooses any two species and view the evolutionary history of each.
What species did you choose?
What is one defining characteristic of the species (that other closely related species do not have)?
What is the closest related living species?
Use the related feature for the two species you chose (hint: watch the video included in the deep tree to learn how to use the related feature). When did these two species diverge? What traits do they have in common?
