The usefulness of the fossil record Many people suppose that evolutionary
relationships among species can be read directly from the fossil record , but this
is seldom the case . For most groups , especially those that do not fossilize

The reader may have noticed that in most modern approaches to phylogenetic
analysis , inferences about the polarity of evolution and the relationships among
taxa are drawn solely from the pattern of distribution of features among taxa ...

Sibley and Ahlquist ( 1983 ) have used this technique to estimate relationships
among many families of birds , and find that these too pass the relative rate test
for constancy of divergence rate . It is interesting that DNA hybridization data do
not ...
