Gather information from secondary sources (including photos/diagrams/models) to observe, analyse and compare the structure of vertebrate forelimbs

the website in kier's response does not have enough info to complete assesment any additional info/sites would be great.

Evidence: Comparative Anatomy
• Certain anatomical similarities bear witness to evolutionary history. The Pentadactyl Limb
• The same skeletal elements make up the forelimbs of humans, cats, whales and bats
– The function of these limbs differ
– If designed would be very different
– However, structural similarities would be expected if they evolved from a common ancestor with the prototype forelimb
Similarity by common ancestry is called homology

Here is a picture of a few different vertebrate forelimbs

I had a pretty good sheet on this that looked at the various bones in the pentadactyl limb but im not sure if i still have it. If i do i will scan it when I find it
