This is not a book for the layperson. It is an advanced work in the development and evolution of behavior. The subtitle: Essays in Memory of T. C. Schneirla (a delading exemplar in the stiudy of behavior). The focus of this book is the complexity of understanding animals' behavior and why it is manifest as it is.
Key point: Neither learning nor genes fully accounts for behavior. We need to consider the complex development of behavior in any species, in which experience and genes are part of a "fused" process. That is, experience, learning, and genes interact with one another as an organism develops. Without considering how these work together, one cannot understand why behavior ends up as it is in any organism.
The chapters elucidate a variety of behaviors across many different species. The various parts of the volume focus on: Evolution of behavior; development of behavior; behavioral processes; Social behavior; Human behavior.
I read this first in a graduate course in animal behavior way back when. It struck me as a powerful work then. Many years have intervened and many new findings and theories have been advanced since then. But the points made are still valuable after many years have passed. . . .
