Ornitologia e dintorni
How are birds related? 
This is not just an academic question. 
Every living thing is the end-product of an evolutionary history and
carries the evidence of that descent. 
Until recently there were only two ways to reconstruct this history: 
from the fossil record and from the constitution and distribution of living things. 
Now there is a third: the comparative studies of DNA and its byproducts, which
form the basis of the work of Charles Sibley and his collaborators.
