The placentals:
3 of them are bolded: Primates (monkeys and apes), Rodentia
(rodents, 40.8% of mammals), Carnivora (cats, dogs, bears
otters, skunks hyenas etc)
Mendelian models we use: Mice and rats are the most common
that we use.
Rodentia is a huge group tends to have a lot of individuals in the
genus that are really close.
Insectivoras (shrews) need to be constantly fed due to their fast
metabolism. Have to check traps every hour because if they are
not fed 1-2hrs they would just die.
Primates:
Strepsirhini (primitive, mainly nocturnal primates)
Haplorhini (modern mainly diurnal primates)
Primates (perspective 2):
Prosimii
Anthropoidea:
oPlatyrhinii (New World Monkeys)
oCatarhinii (Old World monkeys and apes)
Taxonomy that we seen on screen is the most common
Di7erent between the primates order is one is nocturnal, one isn’t
Strepsirhini (primitive, mainly nocturnal primates):
True lemurs
Dwarf lemurs
Indris
Aye-ayes
Galagos, bushbabies
Haplorhini: (former perspective)
Tarsiidae tarsiers
Cebidae (new world monkeys)
Hylobatidae (lesser apes)
Hominidae (great apes and humans)
Carnivores:
Former perspective:
Pinnipeds: Sea carnivores
oSea lions
oSea walruses
