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.
