Were the Germans physically superior?

[Carlton Bach]

As far as I know a Roman soldier had to be at least 1,70 Metres to enter the Roman army. Well, thats not very short for that timeperiod.
And if the Germans were taller, as discribed, means they were commonly
at least 1,80-1,90 Metres what I doubt a little for that time.
Romans had much better food and more variety of food...

There are some skeleton-founds of Romans and Germans, practical would be to simply collect those founds and compare them.

I don't think that would be practical. How would you be able to tell the difference between the bones of a Roman, a Gaul, or a German? You could hardly base it on the location of the burial alone, and once you limit yourself to those skeletons clearly identifiaed by the circumstances of the excavation as Roman or Germanic, the numbers are fairly small.

Averages point that way, of course, but in the end I don't think the material proves more than 'Southern Europweans were shorter than Northern Europeans'.
