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
|
|
AMHS
|
Anatomically modern homo sapiens

|
Crural Index
|
tibia length
------------------
femur length X100
