Evolution : a very short introduction by Brian Charlesworth( Book )

31 editions published between 2003 and 2018 in 4 languages and held by 1,031 WorldCat member libraries worldwide

In less than 500 years science has completely transformed our view of our origins and relationship with the universe. This incisive and though-provoking book introduces some of the most important findings and concepts of evolutionary biology, such as the formation and divergence of species, adaptation, mutation, and natural selection. Brian and Deborah Charlesworth trace the progress of evolutionary thought from the first publications of Darwin and Wallace over 140 years ago, to recent evidence provided by studying evolution at the molecular level. The book ends by showing how evolutionary ideas illuminate some of the hardest questions in modern biology, such as why ageing happens and why some animals behave altruistically

Evolution in age-structured populations by Brian Charlesworth( Book )

13 editions published between 1994 and 2004 in English and Undetermined and held by 375 WorldCat member libraries worldwide

The populations of many species of animals and plants are age-structured, i.e. the individuals present at any one time were born over a range of different times, and their fertility and survival depend on age. The properties of such populations are important for interpreting experiments and observations on the genetics of populations for animal and plant breeding, and for understanding the evolution of features of life-histories such as senescence and time of reproduction. In this new edition Brian Charlesworth provides a comprehensive review of the basic mathematical theory of the demography and genetics of age-structured populations. The mathematical level of the book is such that it will be accessible to anyone with a knowledge of basic calculus and linear algebra
Elements of evolutionary genetics by Brian Charlesworth( Book )

16 editions published between 2010 and 2012 in English and held by 229 WorldCat member libraries worldwide

"Evolutionary genetics considers the causes of evolutionary change and the nature of variability in evolution. The methods of evolutionary genetics are critically important for the analysis and interpretation of the massive datasets on DNA sequence variation and evolution that are becoming available, as well for our understanding of evolution in general. This book shows readers how models of the genetic processes involved in evolution are made (including natural selection, migration, mutation, and genetic drift in finite populations), and how the models are used to interpret classical and molecular genetic data. The material is intended for advanced level undergraduate courses in genetics and evolutionary biology, graduate students in evolutionary biology and human genetics, and researchers in related fields who wish to learn evolutionary genetics. The topics covered include genetic variation, DNA sequence variability and its measurement, the different types of natural selection and their effects (e.g. the maintenance of variation, directional selection, and adaptation), the interactions between selection and mutation or migration, the description and analysis of variation at multiple sites in the genome, genetic drift, and the effects of spatial structure. The final two chapters demonstrate how the theory illuminates our understanding of the evolution of breeding systems, sex ratios and life histories, and some aspects of genome evolution."--Publisher's website

EVOLUTION by Brian Charlesworth( Book )

1 edition published in 2017 in English and held by 19 WorldCat member libraries worldwide

POPULAR SCIENCE. Less than 450 years ago, all European scholars believed that the Earth was at the centre of a Universe that was at most a few million miles in extent, and that the planets, sun, and stars all rotated around this centre. Less than 250 years ago, they believed that the Universe was created essentially in its present state about 6000 years ago. Even less than 150 years ago, the view that living species were the result of special creation by God was still dominant. The recognition by Charles Darwin and Alfred Russel Wallace of the mechanism of evolution by natural selection has completely transformed our understanding of the living world, including our own origins. In this Very Short Introduction Brian and Deborah Charlesworth provide a clear and concise summary of the process of evolution by natural selection, and how natural selection gives rise to adaptations and eventually, over many generations, to new species

The genetic structure of populations by Albert Jacquard( Book )

3 editions published between 1970 and 2014 in English and held by 3 WorldCat member libraries worldwide

It is part of the ideology of science that it is an international enterprise, carried out by a community that knows no barriers of nation or culture. But the reality is somewhat different. Despite the best intentions of scientists to form a single community, unseparated by differences of national and political viewpoint, they are, in fact, separated by language. Scientific literature in German is not generally assimilated by French workers, nor that appearing in French by those whose native language is English. The problem appears to have become more severe since the last war, because the ascendance of the United States as the preeminent economic power led, in a time of big and expensive science, to a pre dominance of American scientific production and a growing tendency (at least among English-speakers) to regard English as the international language of science. International congresses and journals of world circulation have come more and more to take English as their standard or official language. As a result, students and scientific workers in the English speaking world have become more linguistically parochial than ever before and have been cut off from a considerable scientific literature. Population genetics has been no exception to the rule. The elegant and extremely innovative theoreticaI work of Malecot, for example, is only now being properly assimilated by population biologists outside France. It was therefore with some sense of frustration that I read Prof

X chromosome evolution in Drosophila by Beatriz Vicoso( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

Although the X chromosome is usually similar to the autosomes in size, gene density and cytogenetic appearance, theoretical models predict that its hemizygosity in males may cause unusual patterns of evolution. The sequencing of several genomes has indeed revealed differences between the X chromosome and the autosomes in the rates of gene divergence, patterns of gene expression and rates of gene movement between chromosomes. In this thesis, I have attempted to investigate some of these patterns and their possible causes. The first two chapters consist of theoretical and empirical work intended to analyse the rates of evolution of coding sequences of X-linked and autosomal loci, with particular emphasis on faster-X evolution, the theory that more effective selection on the X can lead to higher rates of adaptive evolution on this chromosome. By analyzing X-linked and autosomal coding sequence in several species of Drosophila, we found some evidence for more effective selection on the X, particularly evident in the higher levels of codon usage bias detected at X-linked loci. We argue that this could be due to higher levels of recombination on the X chromosome increasing its effective population size (NeX) relative to the autosomal effective population size (NeA). To further investigate this hypothesis, we have modeled the effect of increased NeX/NeA on rates of evolution and confirmed that this can contribute to faster-X evolution. The last two chapters deal with the evolution of sex-biased genes and the possible causes for their differential accumulation on the X. We used EST data to create expression profiles for D. melanogaster male-, female- and unbiased genes. Our results suggest that the expression levels of sex-biased genes are incompatible with the accepted iii model of sex-biased gene evolution. We also show that the deficit of testis-expressed genes that is observed in Drosophila seems to be stronger for highly expressed genes. In fact, for very lowly expressed genes, we observe a small excess of testis-expressed genes on the X. We attempt to discuss this pattern in view of what is currently known about the evolution of sex-biased gene expression

The effects of breeding systems on genetic architecture by Elie Dolgin( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

Differences in reproductive strategies are a major factor influencing the patterns of genetic variability. Inbreeding and other non-recombining breeding systems can have profound effects on the efficacy of natural selection, which should be manifested in the patterns of genetic diversity within and between species. The impact of an organism's breeding system can be investigated through a number of approaches. In this thesis, I use mathematical modelling, computer simulations, breeding schemes, quantitative life history measures, and molecular biological techniques to explore many of the consequences of breeding system evolution. Following a general introduction in Chapter 1, I explore the dynamics of transposable elements (TEs)-selfish mobile sequences of DNA that have deleterious effects upon their hosts. Sexual reproduction and recombination are important for constraining TE abundance, and in the absence of sex, an unchecked proliferation of TEs may cause a population to go extinct. In Chapter 2, I use a theoretical framework to analyze TE dynamics under asexual reproduction. Here, I show that while small populations are driven to extinction by element accumulation, large asexual populations can prevent this fate and be cured of vertically transmitted TEs. These results may help explain an "evolutionary scandal": the persistence of ancient asexual lineages, such as the bdelloid rotifers. In Chapter 3, I extend the computer simulations used in the previous chapter to explore the effects of reduced recombination on the distribution and abundance of TEs in sexual populations. I show that TEs become fixed as a result of Hill-Robertson effects in the form of Muller's ratchet, but only in regions of extremely low recombination when excision is effectively absent and synergism between elements is weak. These results should help explain genomic patterns of TE distributions. In the remainder of the thesis, I turn to testing the genetic effects of androdioecy-the breeding system in which populations are comprised of separate male and hermaphrodite individuals-using the nematode Caenorhabditis elegans and related species. This unusual breeding system promotes high levels of inbreeding, yet males are maintained at appreciable frequencies. In Chapter 4, I measure lifehistory traits in the progeny of inbred versus outcrossed C. elegans and the related outcrossing species, C. remanei, to compare levels of inbreeding depression. I show that highly inbred C. remanei show dramatic reductions in brood size and relative fitness compared to outcrossed individuals, whereas pure strains of C. elegans performed better than crosses between strains, indicating outbreeding depression. The results are discussed in relation to the evolution of androdioecy and the effect of mating system on the level of inbreeding depression. Like C. elegans, C. briggsae reproduces by self-fertile hermaphrodites, and both species have similarly low levels of molecular diversity. But the global sampling of natural populations has been limited and geographically biased. In Chapter 5, I describe the first cultured isolates of C. elegans and C. briggsae from sub-Saharan Africa, characterize these samples for patterns of nucleotide polymorphism and vulva precursor cell lineage variation, and conduct a series of hybrid crosses in C. briggsae to test for genetic incompatibilities. With the new African isolates, I show distinct differences in levels of genetic and phenotypic diversity between the two species. Despite many similarities between C. elegans and C. briggsae, the results indicate that there may be more subtle, and previously unknown, differences in their natural histories. Finally, I return to the question of the impact of reduced recombination on TE dynamics in Chapter 6, by comparing population frequencies of TEs in natural populations of selfing and outcrossing Caenorhabditis species. I show that in the selfing species, C. elegans, transposons are less polymorphic and segregate at higher frequencies compared with the outcrossing species, C. remanei. Estimates of the intensity of selection based on the population frequencies of polymorphic elements suggest that transposons are selectively neutral in C. elegans, but subject to weak purifying selection in C. remanei. These results are consistent with a reduced efficacy of natural selection against transposable elements in selfing populations
