Vertebrate Life distills the necessary information from vertebrate
anatomy, physiology, ecology, and behavioral studies and then helps
students see important connections across levels of biological
scale. The result is students come to understand how organisms
function effectively in their environments and how lineages of
organisms change through evolutionary time. Processing complex
detailed information about expansive phylogenies and diverse
anatomies can be difficult for even the most motivated students,
and Vertebrate Life addresses this challenge by combining
appropriately-detailed, clearly-written text with outstanding
phylogenies and figures, making it a thorough and engaging
reference for students and instructors alike. The text's impressive
illustration program helps students visualize complex concepts,
allowing them to parse difficult anatomical information. The 11th
edition will have an upgraded illustration program with several new
and revised figures, including layered figures presented in the new
enhanced eBook.
