Homologous Traits
Shared derived traits
Flip
Analogous Traits or Homoplasies
Traits that evolved separately in different lineages, like bird and bat wings
Flip
Strepsirhines
Wet noses (like a dog) called prosimians Includes lemurs and lorises Important features: mandible is not fused Long snouts Smaller brains postorbital bar
Flip
Haplorhines
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 features: postorbital plate large brain dry noses
Flip
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

Flip
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)
Flip
Carrying angle
when the femur angles inwards from the hip towards the knee - unique to humans and their fossil relatives
Flip
Earliest member of homo genus
H. Habilis - coexisted with australopiths and used simple stone tools then came H. erectus Then H. sapeins
Flip
AMHS
Anatomically modern homo sapiens
Flip
Crural Index
tibia length ------------------ femur length X100
Flip
Allen's Rule
Animals in cold climates have shorter extremities
Flip
Bergmann's Rule
States that animals living in colder climates should have bigger body masses
Flip
Demography
Population structure and birth, death, and migration rates
Flip
