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.
