Sympatric speciation in an age-structured population living on a lattice
A square lattice is introduced into the Penna model for biological aging in order to study the evolution of diploid sexual populations under certain conditions when one single locus in the individual’s genome is considered as identifier of species. The simulation results show, after several generations, the flourishing and coexistence of two separate species in the same environment, i.e., one o...
متن کاملDarwin's finches: Population variation and sympatric speciation.
The classical model of the adaptive radiation of Darwin's finches is one of repeated speciation in allopatry. Evidence presented here suggests that sympatric specification may have contributed to the radiation. On Isla Genovesa Geospiza conirostris displays several features that are consistent with a model of sympatric speciation. Males are polymorphic in song type. Those singing song A have si...
متن کاملThe dynamics of a quantitative trait in an age-structured population living in a variable environment.
Time series of rapid phenotypic change have been documented in age-structured populations living in the wild. Researchers are often interested in identifying the processes responsible for such change. We derive an equation to exactly decompose change in the mean value of a phenotypic trait into contributions from fluctuations in the demographic structure and age-specific viability selection, fe...
متن کاملA Note on the Convergence of the Homotopy Analysis Method for Nonlinear Age-Structured Population Models
In this paper, a theorem is proved which presents the series solution obtained from the homotopy analysis method is convergent to the exact solution of nonlinear age-structured population models.
متن کاملSympatric speciation
What is sympatric speciation? The likelihood of sympatric speciation is perhaps the most controversial aspect of speciation, and certainly one of the most contested questions in evolutionary biology. Speciation in general is defined as the evolution of strong, genetically based ‘isolating barriers’ between populations that prevent them from exchanging genes, for example, mate discrimination, ha...
