Not to belabor the point, but 'higher' clearly implies 'more North' (cf.
DownUnder). As none of our humanned-spacecraft have gone 'up' in polar
orbit, they have the record for 'outer' but not 'higher'. I conclude that
the northern-most Redwood and Giraffe are the 'highest organisms'.

BTW, don't ask on a vertebrate biology mid-term, "Which is the largest
order of mammals?" Expecting 'Rodentia', you'll be told 'Cetacea' as often 
as not.

This is better than grading
