RE: juveniles faster than adults

[Jaime Headden <qi_leong@hotmail.com>]

Forgive me for noting that no one quantified either relative speed to mass or 
relative speed to distance in either age group in this estimation, so Greg is 
(technically) correct. The problem here is that relatively muscle to mass and 
performance aspects of limb anatomy DO appear to quantify a differential 
between performance (which may equate to speed) to mass, making juveniles 
faster (relative to mass) than adults; I don't know how to address whether they 
were faster than adults over the same distance, and this I do not think has 
been argued. In other words, we can be assured that juveniles are more _agile_ 
or _nimble_, but unknown whether they were absolutely _faster_ than adults. So 
in this case, Greg is (appropriately) wishy-washy in his response. Applying 
anything further without raw data would be a major mistake.

Cheers,
