Homologous Traits
Shared derived traits
Analogous Traits or Homoplasies
Traits that evolved separately in different lineages, like bird and bat wings
Wet noses (like a dog) called prosimians Includes lemurs and lorises Important features: mandible is not fused Long snouts Smaller brains postorbital bar
dry furry noses (anthropoids) includes tarsiiformes (tarsiers) platyrrhines (new world primates - south and central america) catarrhines (old worlds primates - africa and asian, apes, gibbons, great apes, humans, orangutans, gorillas, chimpanzees and bonobos, hominins) Important fea...
Homologous primate features
five fingers and toes retention of a clavicle Less than 3-1-4-4 dentition (humans are 2-1-2-3) grasping hands and feet nails instead of claws stereoscopic vision reduced sense of smell increased brain size
Order of Epochs
Paleocene 65-56 mya pigs Eocene 56-33 mya eat Oligocene 32-23 mya orange Miocene 23-5.3 mya mucky Plio-pleistocene 5.3-10,000 mya poo
IMI Equation
Intermembral index humerus length + radius length femus length + tibia length X100 long arms have (>100 index), long legs will give (<100) and even length is (=100)
Carrying angle
when the femur angles inwards from the hip towards the knee - unique to humans and their fossil relatives
Earliest member of homo genus
H. Habilis - coexisted with australopiths and used simple stone tools then came H. erectus Then H. sapeins
Anatomically modern homo sapiens
Crural Index
tibia length ------------------ femur length X100

Animals in cold climates have shorter extremities
Bergmann's Rule
States that animals living in colder climates should have bigger body masses
