The frogs in particular are one of the most diverse of the higher
vertebrate
groups and peculiarly endearing animals with their lugubrious expressions and vocabulary of squeaks and belches.
The commonest
vertebrate
remains are of teeth or other resistant pieces.
Even Darwin admitted that his confidence was tested when he contemplated the
vertebrate
eye, although he went on to say that this was more a failure of the imagination than of the intellect.
I do not think that anyone attempting to classify the
vertebrate
s would fail to recognize the Anura as a group, or that, presented with an adult
vertebrate
, one would be in any doubt as to whether or not it was an Anuran.
More than those of any other
vertebrate
group, the teeth of mammals have changed in distinctive ways, and the different types of mammals can be reliably identified from a study of their dentition alone.
The Carboniferous is popularly known as the "Age of Amphibians", and it is true that the amphibians reached a dominance in the
vertebrate
world at this time which they never again equalled.
The skeleton of a

reveals a similar thickening of the bones near the joints, augmented to permit rotation of the hinges.
Vertebrate
remains are decidedly patchy, particularly the terrestrial species.
In each

Even for the three
vertebrate
cases, the ways in which the wing is constructed are quite different, although in each case they are modifications of the same fundamental structure, the pentadactyl limb.
So it is possible to deduce more about the course of evolution from the study of
vertebrate
skeletal remains than is possible with most in
vertebrate
groups, but even now, many mysteries remain.
As an example of induction, consider the development of the
vertebrate
eye.
