From: "wizard" Excuse me? Considering the PPro is significantly older than the PII, it would be hard for it to be the child. Further...the PPro has faster cache (clock == core, as opposed to clock == 1/2 core on PII) and on some versions more cache than the PII (up to 1MB). Clock for clock, the PPro is a better chip than the PII, it simply never got clocked up as high as the PII (for a number of mostly economic reasons).
