The evolution to multicellular organisms determined the appearance
of more sophisticated and specialized systems for the different
physiologies like integumentary, respiration, digestion, excretion,
circulatory, reproduction, skeletal and the nervous system. In the
line of chordate evolution, advent of tetrapods have triggered the
events leading to only partial dependence on water for
physiological activities. The inconstant environment in which
animals lives largely determine and guides the way animal
physiology evolves. This directs the anatomical and morphological
changes in the organism that translates into varied and diverse
physiological process. This book describes the transition of life
from aquatic to terrestrial habitat that brings about changes in
feeding habit and subsequent anatomical and morphological changes
in the digestive tract. Similar transition also guides
modifications in urino-genital system due to demands of removing
ammonia/urea or uric acid as excretory waste. The author of this
book further explores the evolution of tetrapods as one major event
in the evolutionary history of chordates in addition to adaptive
radiation. This has transformed the locomotion from Fins' to Feet'.
Demands of terrestrial life also means metabolism and energy
requirements has to be met for which circulatory system was
modified to incorporate more chambers and double circulation for
warm bloodedness and increased metabolism to meet the energy
requirements of life on land. Subsequently, as explored in the
book, different organ systems underwent modification in
organization to work together the best physiological adaptations to
sustain life on earth.
