Discontinuous variability of brain composition among domestic chicken breeds.

Brain, behavior and evolution - 1 Jan 2003

Rehkämper Gerd, Kart Emriye, Frahm Heiko D, Werner Christian W

Abstract excerpt

In 80 domestic chickens from 8 breeds, the volumes of 12 brain parts were identified as dimensions in a cluster analysis. Based on Euclidean metrics and the Ward algorithm at least 2 groups were found that are congruent with the breeds 'White Crested Polish chicken' and 'Breda', although the breed identity was not a variable used in the cluster analysis. Domestication is interpreted as evolution which includes...
