This second edition of Comparative Anatomy of Vertebrates has been
thoroughly revised. It is based around two fundamental themes. Part
A, comprising the first eight chapters, is devoted to the
discussion of chordates' evolution and classification. A detailed
taxonomic synopsis for each class is included in the chapter
dealing with that class. In addition a combination of phylogenetic
trees (cladograms) and narrative discussions to unveil facts about
animal evolution are included. Cladograms are used where
appropriate. The book also discusses molecular-based hypotheses
that have received widespread attention. Part B deals with
comparative anatomy and provides an introduction to the
structure-function concept at the level of organs and the organ
system, which is fundamental to the understanding of synthesis of
comparative anatomy. Key features: Treats the subject in a
sequential manner Brief and lucid discussion of the subject matter
Outline diagrams, taken from authentic sources, that can be easily
reproduced
An adaptation, or adaptive trait, is any heritable trait, that
enables organisms to survive through natural selection and
reproduce better under prevailing environmental conditions. Natural
selection tends to preserve beautiful adaptation in populations and
discard harmful ones. The evolution of animal form and function is
the conceptual backbone of this book. It not only provides the
framework for Animal Diversity, but also shifts the paradigm from a
chiefly descriptive discipline to a dynamic predictive science. It
is a book narrating rambling series of stories or vignettes about
randomly selected animals or model organisms and their unique way
of life. Animals might not be able to speak or master advanced
language techniques, but they certainly have other ways of
communications. Species often rely on verbal and nonverbal forms of
communication, such as calls, nonvocal auditory outbursts, like the
slap of a dolphin’s tail on the water; bioluminescence; scent
marking; chemical or tactile cues; visual signals and postural
gestures. When it comes to acoustic communication, not every member
of a species is just alike. Animals in different regions have often
been overheard sounding off in different dialects. Communication
between species can play important roles as well. One study
suggested that the reason Madagascan spiny-tailed Iguana have
well-developed ears, despite the fact that they don’t communicate
vocally is so that they can hear the warning calls of the
Madagascan paradise flycatcher. The book is weaved intricately
around these bizarre adaptations.
