Deep Homology?

This book provides a comparison of the genetic circuits of Homo sapiens and Drosophila melanogaster to reveal the evidence for deep homology, from the field of evolutionary developmental biology. Individual body parts including the nervous system, limbs and heart are compared in chapters that also feature concept maps and encyclopaedic tables to aid learning.

Humans and flies look nothing alike, yet their genetic circuits are remarkably similar. Here, Lewis I. Held, Jr compares the genetics and development of the two to review the evidence for deep homology, the biggest discovery from the emerging field of evolutionary developmental biology. Remnants of the operating system of our hypothetical common ancestor 600 million years ago are compared in chapters arranged by region of the body, from the nervous system, limbs and heart, to vision, hearing and smell. Concept maps provide a clear understanding of the complex subjects addressed, while encyclopaedic tables offer comprehensive inventories of genetic information. Written in an engaging style with a reference section listing thousands of relevant publications, this is a vital resource for scientific researchers, and graduate and undergraduate students.
