The location that should have lowest oxygen concentration would be the tissue because it is the furthermost location.
Other location with lowest oxygen concentration should be in the right part of the heart. It is when all unoxygenated blood pooled before going to the lungs. But the left part of the heart will have highest oxygenated blood, so it's ambiguous.

Throughout the generations, it shows that the number of short legs have decreased, and the number of medium length legs neither have advantage or disadvantage.
