Genetic differentiation during speciation

Nature, 1978
SPECIATION theory is still largely descriptive. How many and what kind of genes are implicated in speciation is a central unresolved problem of evolutionary biology1,2. Does speciation require major genomic changes3–5 or may minor ones suffice1,6–9? Similarly, does speciation depend on structural or on regulatory genes10?

Genetic algorithm with geographic speciation

2012 8th International Conference on Natural Computation, 2012
Genetic algorithm (GA) is a bionic algorithm which is widely used for optimization problems. It was initially coined by professor Holland in University of Michigan who took advantage of some phenomenon in natural evolution, such as crossover, mutation, selection and inheritance. However, there is a longstanding problem of genetic algorithm.

GENETIC DIVERGENCE AND HYBRID SPECIATION

Evolution, 2007
Although the evolutionary importance of natural hybridization has been debated for decades, it has become increasingly clear that hybridization plays a fundamental role in the evolution of many plant and animal taxa, sometimes resulting in the formation of entirely new species.

Genetics and speciation

Nature, 1992
Called the "mystery of mysteries" by Darwin, speciation is still a little-understood area of evolution. Genetic analysis, however, has yielded new generalizations about speciation and suggests promising avenues of research.

Speciation genetics: evolving approaches

Nature Reviews Genetics, 2006
Much progress has been made in the past two decades in understanding Darwin's mystery of the origins of species. Applying genomic techniques to the analysis of laboratory crosses and natural populations has helped to determine the genetic basis of barriers to gene flow which create new species. Although new methodologies have not changed the prevailing

The Ecological Genetics of Speciation

The American Naturalist, 2002
Ecological interactions and the natural selection they cause play a prominent causal role in biological diversification and speciation. As a discipline, ecological genetics integrates the two components of adaptive evolution (natural selection and genetic variability) to study the mechanisms of evolution.

Competitive Speciation in Quantitative Genetic Models

Journal of Theoretical Biology, 2000
We study sympatric speciation due to competition in an environment with a broad distribution of resources. We assume that the trait under selection is a quantitative trait, and that mating is assortative with respect to this trait. Our model alternates selection according to Lotka-Volterra-type competition equations, with reproduction using the ideas ...

Biochemical Population Genetics and Speciation

Evolution, 1982
Although the currently most popular concept of species and speciation is described as a "synthetic" or "biological" one, it is a population-genetic concept in its essence, since it was in its terms that the synthesis of Darwinian natural selection and Mendelian genetics was realized (Chetverikov, 1926; Fisher, 1930; Haldane, 1932; Dobzhansky, 1937 ...
