:: Phylogenetic Tree: How Everything Connects!  



Go here to delve deeper into the Phylogenetic tree!

Explanation of Trees

Shown in the first tree is that Rodentia and Primates are related through Euarchontoglires.  In the second tree, two of the three primary branches, Hystricomorpha and Myomorpha, are connected to Rodentia.  Thus, the common ancestor between Myomorpha, Hystricomorpha and Primates is Euarchontoglires.  The first tree is to show the common ancestor for the second tree primary branches.  The second tree is what we will be looking at extensively. 

Primates branch off into two main groups of Homo sapiens (people) and Presbytis entellus (common langur)The Rodentia group branches off into many more organisms.  Two defining groups of Rodentia are Hystricomorpha and Myomorpha.  Myomorpha gives rise to Mus musculus (house mouse) and further down the road Mesocricetus auratus (golden hamster) and Ondatra zibethicus (muskrat).

Hystricomorpha branches off into Cavia porcellus B (guinea pig), Proechimys guairae (Guaira spiny rat), Chinchilla brevicaudata (chinchilla), and Myocastor coypus (coypu)The last branch of Hystricomorpha ends with Cavia porcellus A (the guinea pig we are dealing with), and Hydrochoerus hydrochaeris (capybara).

All of these organisms are under the Kingdom Animalia.
