Peter R. Grant Quotes
"The independent role of morphology in mate choice is revealed by the rare instances where the usual association between song and morphology is disrupted."
- Peter R. Grant
(Related: Choice, Song)
"The process of speciation is completed with the cessation of genetic exchange."
- Peter R. Grant
"The theory of founder effects does not explain how novel features like plumage traits arise."
- Peter R. Grant
(Related: Theory)
"Thus mating of females was strictly along the lines of paternal song."
- Peter R. Grant
(Related: Song)
"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."
- Peter R. Grant
(Related: Inheritance)
"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."
- Peter R. Grant
(Related: Life, Learning, Song)
"The divergence of songs in the new population away from those in the progenitor population would only be prevented if these processes were balanced by repeated immigration and subsequent breeding: song flow."
- Peter R. Grant
(Related: Population, Song, Songs)
"We observe closely related species in sympatry and infer how they evolved from a common ancestor."
- Peter R. Grant
"Almost nothing is known from hybridization studies about the inheritance of courtship behavior of females, or of their responsiveness to particular male signals."
- Peter R. Grant
(Related: Behavior, Courtship, Inheritance, Nothing)
"Males transmit signals in courtship through behavioral displays."
- Peter R. Grant
(Related: Courtship)
"Plumage features constitute a major component of courtship signals."
- Peter R. Grant
(Related: Courtship)
"Genes that underlie the capacity to receive, use and transmit information are the evolving properties."
- Peter R. Grant

"Exchange of breeding individuals between two populations tends to homogenize their gene pools."
