Rhythms of life

de Edward S. Ayensu, Philip Whitfield

"Beginning with the rhythms of daily life, the book then shifts, taking a longer view to show how the rhythms of the cosmos affect the lives of all the creatures on earth ... The book looks in detail at biological clocks and what makes them tick. Then it studies particular aspects of life, including reproduction, growth, feeding, sleeping, and moving in order to discover the rhythms and cycles that underlie each"--Publisher description.
