Yup.
My niece is 6'2". She's even tall for the WNBA. A friend of my son's played center for the University of Connecticut, then for the LA Sparks. She was also 6'2".
6'6"? That's almost unheard of. Now add;
* Feral
* Strong beyond the abilities of men in the region
* Covered with hair
* Can sprint as fast as a horse
* Can swim raging rivers in winter
* Sleeps outside without clothing or bedding in subfreezing winter cold
How unique is this? She is the only known example.
We don't have her skeleton, but her half breed son's skull is clearly unique.
So if Zana is now proven to be not only human, but Homo sapien, what are the chances that ALL of such examples are feral homo sapiens? As fantastic as that question seems, that answer appears to be scientifically likely. That answer explains:
* Their rare status, low numbers, and wide range
* Reports of extremely huge specimens and average sized specimens
* The repeated returns of human dna tests on various samples thought to be contaminated
* Government unwillingness to get involved
* Aboriginal descriptions that they are, indeed, wild people
