This photo shows the arm bones together and the leg bones together for one species of primate. Use the ruler in the image to approximate the intermembral index. Review the answer options below and select all that apply.
Intermembral index = (radius + humerus) / (femur + tibia) x 100
The femur is easily identified by the ball joint of the femoral head.
Group of answer choicesthe arm length is longer than the leg lengththe leg length is longer than the arm length
Intermembral index of about 140
iIntermembral index of about 105
intermembral index of about 85
this is an example of a brachiator
this is an example of a vertical clinger and leaper
this is an example of a terrestrial quadruped

This photo shows the right os coxae and part of the sacrum of a chimpanzee pelvis. Use the ruler to estimate the iliac blade width and height and calculate the ilium index. Select all correct answers from the options below.
Ilium Index = ( Iliac blade width / iliac blade height ) x 100
Group of answer choicesIliac index is approximately 100iliac index is approximately 64
ilium blade is long and narrow
ilium blade is short and wide
This photo shows the right os coxae and part of the sacrum of a human pelvis. Use the ruler to estimate the iliac blade width and height and calculate the ilium index. Select all correct answers from the options below. The ruler for the blade height is at an angle for a reason :)
