Evolution: Replacing Genes and Traits through Hybridization
The role of hybridization in evolution has been debated for over a century. Recent molecular genetic studies indicate that hybridization is surprisingly frequent in natural populations, and that it may allow populations to regain traits that have been lost and possibly to replace damaged alleles with functional copies from related species.
متن کاملHybridization of Differential Evolution for Aerodynamic Design
Differential Evolution is a genetic algorithm which has been shown to be a robust but inefficient optimizer for aerodynamic design problems, requiring thousands of function evaluations to converge. Differential Evolution is combined with a local search engine to create a new hybridized algorithm. The optimizers are then used to design several fan blade shapes, in order to compare their performa...
متن کاملHybridization and the evolution of reef coral diversity.
Hundreds of coral species coexist sympatrically on reefs, reproducing in mass-spawning events where hybridization appears common. In the Caribbean, DNA sequence data from all three sympatric Acropora corals show that mass spawning does not erode species barriers. Species A. cervicornis and A. palmata are distinct at two nuclear loci or share ancestral alleles. Morphotypes historically given the...

15 صفحه اولRapid adaptive evolution of northeastern coyotes via hybridization with wolves.
The dramatic expansion of the geographical range of coyotes over the last 90 years is partly explained by changes to the landscape and local extinctions of wolves, but hybridization may also have facilitated their movement. We present mtDNA sequence data from 686 eastern coyotes and measurements of 196 skulls related to their two-front colonization pattern. We find evidence for hybridization wi...
