Demographic parameters and natural selection.
This paper introduces two new demographic parameters, the entropy and the reproductive potential of a population. The entropy of a population measures the variability of the contribution of the different age classes to the stationary age distribution. The reproductive potential measures the mean of the contribution of the different age classes to the growth rate. Using a relation between these ...
متن کاملNatural Selection and the Parameters of Population Growth
The intrinsic rate of natural increase, r, is a constant hat measures the ability of a population to grow under a given set of conditions. The Malthusian parameter, m, is a measure of genotypic rate of increase. Although the mathematical formulations for r and m are the same, their biological characteristics are different except in isogenic populations. Selection will always favor genotypes wit...
متن کاملNatural Language and Natural Selection
Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every ten...
متن کاملSignatures of demographic history and natural selection in the human major histocompatibility complex Loci.
Many lines of evidence show that several HLA loci have experienced balancing selection. However, distinguishing among demographic and selective explanations for patterns of variation observed with HLA genes remains a challenge. In this study we address this issue using data from a diverse set of human populations at six classical HLA loci and, employing a comparative genomics approach, contrast...
