biology statistics

[Chris Drake]

Forgive me a silly question, but it seemed by the title that someone here
might have the answer to this one.  I am an archaeologist and have been
working on some statistical questions about human remains and I was
wondering if there is a fundamental reason why seemingly all physical data
are normally distributed.  It seems that all biological measurements are
normally distributed data: height, weight etc.  I would appreciate it if
anyone could e-mail me or reply here with the answer.  Thanks.

Chris
