Bücher von Peter H. Klopfer

One of the attractive features of the great classical ethologists was their readiness to ask different kinds of questions about behavior - and to do so without muddling the answers.

This volume is subtitled "Alternatives" because we wanted to devote at least a part of it to the alternative ways in which members of the same species behave in a given situation. Alternative modes of behavior, though now familiar, raise particularly interesting questions about current function, evolutionary history, and mechanism.

This volume is devoted principally to the theme of behavioral develop ment. Although the ex cluded middle is familiar enough in academic argument, the dynamic tensions actually present in developing systems may be particularly prone to polarize debate about what is actually happening.
