Molecular signatures of resource competition: clonal interference drives the emergence of ecotypes

It is found that large mutational inputs can foster diversification under sympatry, increasing the probability that phenotypically and genetically distinct clusters arise and stably coexist, constituting an initial form of community.

Analysis of genetic diversity in a close population of Zandi sheep using genealogical information

In a Fisher–Wright idealized population (Fisher 1930; Wright 1931), characterized by Poisson distribution of family size, large number of breeders, random mating, equal sex ratio, absence of

Behavioural correlates with hemipenis morphology in New World natricine snakes

It is suggested that sexual conflict over copulation duration may have shaped the evolution of hemipenis morphology, favouring more elaborate organs in species in which a long duration of copulation is especially beneficial to males, despite the associated costs to females.

Rôle de l'information dans l'acquisition des partenaires sexuels et le choix du sexe de la descendance chez les hyménoptères parasitoïdes : exemple de Venturia Canescens Gravenhorst (Hymenoptera : Ichneumonidae)

La sex-ratio est biaisee en faveur des femelles, mais contrairement aux predictions des modeles theoriques, le choix du sexe de the descendance ne semble pas dependre des informations liees aux conspecifiques.

Mechanisms of reinforcement in natural and simulated polymorphic populations

Congruence of the results for allele frequencies versus fixation probabilities suggests that similar patterns of reinforcement are expected during different stages of the speciation process.

Intergenerational transmission of fertility, review of up to date research and some new evidence from Bejsce parish register reconstitution study, 18 th - 20 th centuries, Poland.

extended The paper aims at the review of up to date research on th e issue of intergenerational transmission of fertility. It the results obtained f rom various data, periods, population and

The major transitions in the evolution of language

The main challenges in evolutionary linguistics are to explain how three major linguistic innovations could have spread through a population where they are initially rare, and how universal properties and tendencies in natural languages can result from the intricate interaction between innate learning biases and a process of cultural evolution over many generations.

On the change of population fitness by natural selection2 3

A general equation for the role of additive, dominance, and epistatic components of fitness in determining the rate of change in population fitness is given and claims that this law should hold the same position among the biological sciences as the second law of thermodynamics in physical sciences.



An Autosomal Bristle Modifier, Affecting a Sex-Linked Character

The semiforked modifier rarely produces any visible effect when homozygous unless the forked gene is present, so it is unlikely that heterozygous forked flies are affected.

An Investigation by Pedigree Breeding into the Polymorphism of Papilio polytes, Linn

The following paper gives an account of a series of breeding experiments which were made with the butterfly Papilio polytes , Linn., in the course of one and a half years’ research on insect

The Variation of Animals and Plants under Domestication

This series offers not only works by Darwin, but also the writings of his mentors in Cambridge and elsewhere, and a survey of the impassioned scientific, philosophical and theological debates sparked by his ‘dangerous idea’.
