The width of our palm, an the length of our hand.
These can't be used for accurate measurement because their size and length vary from person to person and therefore are not universal.

The width of our palm, and the length of our hand. Also the width of feet.
Although similar in many ways, there are clear physical differences distinguishing Neanderthals and modern humans.
Neanderthals were significantly shorter and stockier than modern humans, with much broader rib cages and pelvises. To give some perspective, the average height for a man in the USA is 1.76 metres. Conversely, based on the fossil records available, the average height for a Neanderthal was just 1.6 metres.
A study published late last year suggested that some of these anatomical differences could be the result of the Neanderthals being forced to adopt a much more high protein diet than modern humans.
