Evolution Quotes by Peter R. Grant

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

— Peter R. Grant

Closely related species of birds are also chromosomally similar.

— Peter R. Grant

Evidence of epistasis from hybridization studies is more scarce.

— 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

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

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

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

The process of speciation is completed with the cessation of genetic exchange.

— Peter R. Grant

Plumage features constitute a major component of courtship signals.

— Peter R. Grant

Males transmit signals in courtship through behavioral displays.

— Peter R. Grant

The theory of founder effects does not explain how novel features like plumage traits arise.

— Peter R. Grant

Genes that underlie the capacity to receive, use and transmit information are the evolving properties.
