Abstract
In 1963, Niko Tinbergen published his foundational manuscript identifying the four questions we ask in animal behavior—how does the behavior emerge across the lifespan (development); how does it work (mechanism); how and why did it evolve (evolution); and why is it adaptive (function). Tinbergen clarified that these ‘levels of analysis’ are complementary, not competing, thereby avoiding many fruitless scientific debates. However, the relationships among the four levels was never established. Here, we propose ‘leveling’ Tinbergen's questions to a single temporal timescale divided into causes (encompassing mechanism, development, and evolution) and consequences (encompassing function). Scientific advances now seamlessly link evolution, development, and mechanism into a continuum of ‘causes’. The cause–consequence distinction separates the processes that precede (and lead to) a behavior, from the processes that come after (and result from) a behavior. Even for past behaviors, the functional outcomes are (historical) consequences of the causes that preceded them.
期刊介绍:
Evolutionary Anthropology is an authoritative review journal that focuses on issues of current interest in biological anthropology, paleoanthropology, archaeology, functional morphology, social biology, and bone biology — including dentition and osteology — as well as human biology, genetics, and ecology. In addition to lively, well-illustrated articles reviewing contemporary research efforts, this journal also publishes general news of relevant developments in the scientific, social, or political arenas. Reviews of noteworthy new books are also included, as are letters to the editor and listings of various conferences. The journal provides a valuable source of current information for classroom teaching and research activities in evolutionary anthropology.
