Thus the genetic basis to the origin of bird species is to be sought in the inheritance — Peter Raymond Grant
The theory of founder effects does not explain how novel features like plumage traits arise. — Peter Raymond Grant
The independent role of morphology in mate choice is revealed by the rare instances — Peter Raymond Grant
The divergence of songs in the new population away from those in the progenitor — Peter Raymond Grant
Islands are known to differ in the food supply available to ground finches, mainly seeds. — Peter Raymond Grant
Genes that underlie the capacity to receive, use and transmit information are the evolving properties. — Peter Raymond Grant
Exchange of breeding individuals between two populations tends to homogenize their gene pools. — Peter Raymond Grant
We observe closely related species in sympatry and infer how they evolved from a common ancestor. — Peter Raymond Grant
