"Thus the genetic basis to the origin of bird species is to be sought in the inheritance of adult traits that are subject to natural and sexual selection."
Inheritance
"The independent role of morphology in mate choice is revealed by the rare instances where the usual association between song and morphology is disrupted."
Choice
"To summarize, the particular song a male sings, and the behavioral responses of females to song and morphological signals, are not genetically inherited in a fixed manner but are determined by learning early in life."
Life
"Almost nothing is known from hybridization studies about the inheritance of courtship behavior of females, or of their responsiveness to particular male signals."
Behavior
"The theory of founder effects does not explain how novel features like plumage traits arise."
Theory
"Species can be recognized by their morphological characteristics and songs."
Music
