Hybridization as an invasion of the genome.

Hybridization between species is commonplace in plants, but is often seen as unnatural and unusual in animals. Here, I survey studies of natural interspecific hybridization in plants and a variety ofExpand

Hybrid speciation
Botanists have long believed that hybrid speciation is important, especially after chromosomal doubling (allopolyploidy). Until recently, hybridization was not thought to play a very constructiveExpand

Hybridization and speciation
Hybridization has many and varied impacts on the process of speciation. Hybridization may slow or reverse differentiation by allowing gene flow and recombination. It may accelerate speciation viaExpand

  • 1 July 1995
One hundred and thirty-six years since On the Origin of Species 3., biologists might be expected to have an accepted theory of speciation. Instead, there is, if anything, more disagreement aboutExpand

  • 29 April 2002
The existence of a continuous array of sympatric biotypes - from polymorphisms, through ecological or host races with increasing reproductive isolation, to good species - can provide strong evidenceExpand

Butterfly genome reveals promiscuous exchange of mimicry adaptations among species
The evolutionary importance of hybridization and introgression has long been debated. Hybrids are usually rare and unfit, but even infrequent hybridization can aid adaptation by transferringExpand

Genome-wide evidence for speciation with gene flow in Heliconius butterflies.
Most speciation events probably occur gradually, without complete and immediate reproductive isolation, but the full extent of gene flow between diverging species has rarely been characterized on aExpand

Reproductive isolation caused by colour pattern mimicry
Speciation is facilitated if ecological adaptation directly causes assortative mating, but few natural examples are known. Here we show that a shift in colour pattern mimicry was crucial in theExpand

EVOLUTION OF DIVERSITY IN WARNING COLOR AND MIMICRY: Polymorphisms, Shifting
▪ Abstract Mimicry and warning color are highly paradoxical adaptations. Color patterns in both Mullerian and Batesian mimicry are often determined by relatively few pattern-regulating loci withExpand

  • 27 September 2008
Species are generally viewed by evolutionists as ‘real’ distinct entities in nature, making speciation appear difficult. Charles Darwin had originally promoted a very different uniformitarian viewExpand
