Almost nothing is known from hybridization studies about the inheritance of courtship behavior of females, or of their responsiveness to particular male… — Peter R. Grant Copy Share Image
Thus the genetic basis to the origin of bird species is to be sought in the inheritance of adult traits that are… — Peter R. Grant Copy Share Image
Exchange of breeding individuals between two populations tends to homogenize their gene pools. — Peter R. Grant Copy Share Image
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 Copy Share Image
To summarize, the particular song a male sings, and the behavioral responses of females to song and morphological signals, are not genetically inherited in… — Peter R. Grant Copy Share Image
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 Copy Share Image
The divergence of songs in the new population away from those in the progenitor population would only be prevented if these processes were balanced… — Peter R. Grant Copy Share Image
The process of speciation is completed with the cessation of genetic exchange. — Peter R. Grant Copy Share Image
Plumage features constitute a major component of courtship signals. — Peter R. Grant Copy Share Image
The theory of founder effects does not explain how novel features like plumage traits arise. — Peter R. Grant Copy Share Image
Genes that underlie the capacity to receive, use and transmit information are the evolving properties. — Peter R. Grant Copy Share Image
