Peter R Grant quotes
" A major task for evolutionary biologists is to explain the origin of biodiversity. "

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
" Although speciation is ecologically driven, reproductive (mating) interactions at secondary contact are far from irrelevant. "

Peter R Grant
" Closely related species of birds are also chromosomally similar. "

Peter R Grant
" Despite the evidence against reinforcement, the basis of premating isolation does not evolve entirely in allopatry. "

Peter R Grant
" Evidence of epistasis from hybridization studies is more scarce. "

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

Peter R Grant
" For example, an ecologist's world can make perfect sense, in the short term at least, in the absence of evolutionary considerations. "

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

Peter R Grant
" If continental speciation is promoted by temporarily insular conditions the demography and genetics of founding populations may be of importance. "

Peter R Grant
" If evolutionary divergence in allopatry has been minor before the interchange, the members of the two populations are likely to treat each other as potential mates and interbreeding will ensue. "

Peter R Grant
" If postmating isolation evolves in allopatry, hybridization at the sympatric stage will be lacking, or at most extremely rare and of little consequence. "

Peter R Grant
" In broad outline the last stages of speciation are known, but the genetic basis to the physiological details of postmating isolation are not. "

Peter R Grant
" Islands are known to differ in the food supply available to ground finches, mainly seeds. "

Peter R Grant
" Males transmit signals in courtship through behavioral displays. "
