Extraordinary viral sequence diversity and rapid viral genetic evolution are hallmarks of hepatitis C virus (HCV) infection. Viral sequence evolution has previously been shown to mediate escape from cytotoxic T-lymphocyte (CTL) and neutralizing antibody responses in acute HCV infection. HCV evolution continues during chronic infection, but the pressures driving these changes are poorly defined. We analyzed plasma virus sequence evolution in 5.2-kb hemigenomes from multiple longitudinal time points isolated from individuals in the Irish anti-D cohort, who were infected with HCV from a common source in 1977 to 1978. We found phylogenetically distinct quasispecies populations at different plasma time points isolated late in chronic infection, suggesting ongoing viral evolution and quasispecies replacement over time. We saw evidence of early pressure driving net evolution away from a computationally reconstructed common ancestor, known as Bole1b, in predicted CTL epitopes and E1E2, with balanced evolution toward and away from the Bole1b amino acid sequence in the remainder of the genome. Late in chronic infection, the rate of evolution toward the Bole1b sequence increased, resulting in net neutral evolution relative to Bole1b across the entire 5.2-kb hemigenome. Surprisingly...

Laboratory evolution has generated many biomolecules with desired properties, but a single round of mutation, gene expression, screening or selection, and replication typically requires days or longer with frequent human intervention. Because evolutionary success is dependent on the total number of rounds performed, a means of performing laboratory evolution continuously and rapidly could dramatically enhance its effectiveness. Although researchers have accelerated individual steps in the evolutionary cycle, the only previous example of continuous directed evolution was the landmark study of Wright and Joyce, who continuously evolved RNA ligase ribozymes with an in vitro replication cycle that unfortunately cannot be easily adapted to other biomolecules. Here we describe a system that enables the continuous directed evolution of gene-encoded molecules that can be linked to protein production in Escherichia coli. During phage-assisted continuous evolution (PACE), evolving genes are transferred from host cell to host cell through a modified bacteriophage life cycle in a manner that is dependent on the activity of interest. Dozens of rounds of evolution can occur in a single day of PACE without human intervention. Using PACE, we evolved T7 RNA polymerase (RNAP) variants that recognize a distinct promoter...

peer-reviewed; Modern software systems are prone to a continuous evolution under frequently varying requirements. Architecture-centric software evolution enables change in system structure and behavior while maintaining a global view of software to address evolution-centric tradeoffs. The Lehman’s law of continuing change demands for long-living and continuously evolving architectures to prolong the productive life and economic value of deployed software. However, the existing solutions for architectural maintenance and evolution fall short of exploiting generic and reusable expertise to address recurring evolution problems. We argue that architectural evolution process requires an explicit evolution-centric knowledge – that can be discovered, shared and reused – to anticipate and guide change management. Therefore, we propose a pattern language (PatEvol) as a collection of interconnected change patterns that enable reuse-driven and consistent evolution in component-based software architectures (CBSAs). Pattern interconnections represent possible relationships among patterns (such as variants or related patterns) in the language. In component-based architectures, hierarchal configurations of atomic and composite elements express computational components and their connectors to develop and evolve software. More specifically...

The study of the plants and animals that live on island has been a frequent key to understanding the processes of evolution that determine biotic diversity globally. Insular endemic mammals represent a special ground for the study of evolutionary mechanisms and speciation processes in response to the special characteristics of island environments. Endemic bovids are intriguing elements of insular faunas and offer an extensive and diversified sample for exploring patterns of insular evolution of large-sized mammals. This thesis provides the first comprehensive study on the evolution of extinct and living insular bovids, exploring the selective biotic and abiotic factors that influenced ecogeographic patterns of body mass variation and peculiar morphological changes (e.g., hypsodonty and low-gear locomotion) of these taxa. I show that the majority of island bovids, as large mammals, do follow the main prediction of the island rule, showing a body size reduction, and that ecological release and resource limitation are the main factors influencing body size evolution of these taxa. My results indicate that hypsodonty (increase in molar crown height), a quite common morphological trend in insular artiodactyls, is shared by the majority of insular bovids independently from the abrasiveness of the current diet. The evolution of this feature appear to result from an expansion of the dietary niche under resource limitation...

We investigated the putative association between the parasitic lifestyle and an accelerated rate of mt genetic divergence, compositional bias, and gene rearrangement, employing a range of parasitic and nonparasitic Diptera and Hymenoptera. Sequences were obtained for the cox1, cox2, 16S, 28S genes, the regions between the cox2 and atp8 genes, and between the nad3 and nad5 genes. Relative rate tests indicated generally that the parasitic lifestyle was not associated with an increased rate of genetic divergence in the Diptera but reaffirmed that it was in the Hymenoptera. Similarly, a departure from compositional stationarity was not associated with parasitic Diptera but was in parasitic Hymenoptera. Finally, mitochondrial (mt) gene rearrangements were not observed in any of the dipteran species examined. The results indicate that these genetic phenomena are not accelerated in parasitic Diptera compared with nonparasitic Diptera. A possible explanation for the differences in the rate of mt molecular evolution in parasitic Diptera and Hymenoptera is the extraordinary level of radiation that has occurred within the parasitic Hymenoptera but not in any of the dipteran parasitic lineages. If speciation events in the parasitic Hymenoptera are associated with founder events...

In drei Schwerpunkten wurde die Evolution der Double psi beta-barrel Proteine und Aspartatproteasen untersucht. Im ersten Schwerpunkt ging es um die Faltungen Double psi beta-barrel, deren Vertreter als N-terminale Domänen von AAA-ATPasen wie Vat oder Cdc48 vorkommen, und Acid proteases, zu der die Aspartatproteasen Pepsin und HIV-1 Protease gehören. Obwohl die Strukturen dieser Faltungen bereits als sehr ähnlich erkannt und beschrieben wurden, werden sie bisher als analoge Strukturen mit konvergenter Evolution beschrieben. Dies stützte sich vor allem auf die fehlende Sequenzähnlichkeit und geringe Unterschiede der topologischen Verknüpfung ihrer beta-Stränge. In dieser Arbeit sollten funktionelle Untersuchungen Hinweise auf eine mögliche gemeinsame Abstammung dieser Faltungen liefern. Dazu wurden Chaperonassays durchgeführt, welche Aggregationsverhinderung als funktionelle Gemeinsamkeit von Vertretern dieser Faltungen offenbarten. Die Ergebnisse bestärkten die Vermutung, die Vertreter dieser Faltungen als entfernte Verwandte zu betrachten. Damit wurde ein weiteres Beispiel geliefert, wie sich eine Faltung durch divergente Evolution ändern kann und dies zu verwandten Proteinfaltungen führt. Ein zusätzlicher Aspekt in diesem Schwerpunkt war die Frage...

Objects are naturally occurring items or artificially made artifacts that subjects – humans and animals – act with. They serve as tools in the widest sense: they are used to do something. As part of an activity they are the material expressions of cogitation, especially the ability to think outside the box. The making and use of objects is always tied to a goal that cannot be achieved directly, but only by means of a medium: the need for enhancement of individual faculties is perceived, and an object – not just any, but one that fits the challenge – is found or devised to answer the problem. Object or tool behavior is a particular aspect of behavior that is based on causal connections and – at least partially – considerations thereof. Although the use of tools in the animal kingdom is widespread, it is by no means universal. Contemporary human behavior is characterized by the constant use of objects or tools. The solution of common problems and challenges, and, in extension, human life, without the presence and aid of utensils is inconceivable. Humanity is not characterized by physical and intellectual traits alone, but only becomes comprehensible through its unbreakable bond to inanimate objects, which through use become part of actions and thus of the human world. The connection between the consciously acting human subject and an object is established by means of cognitive processes...

peer-reviewed; Software systems continuously evolve as a consequence of frequent changes in their functional requirements and the environment surrounding them. Architecture-centric software evolution (ACSE) enables changes in software structure and behaviour while abstracting the complex implementation-specific details. However, due to recurring evolution there is a need for solutions that enable a systematic reuse of frequent changes in software architectures. In recent years, architecture change patterns and evolution styles proved successful in promoting reuse expertise to tackle architecture evolution. However, there do not exist any solutions that enable a continuous acquisition and application of architecture evolution knowledge to systematically address frequent changes in software architectures. In this paper, we propose a framework PatEvol that aims to unify the concepts of i) software repository mining and ii) software evolution to enable acquisition and application of architecture evolution knowledge. In the proposed PatEvol framework, we present knowledge acquisition (architecture evolution mining) to enable post-mortem analysis of evolution histories to empirically discover evolution-centric knowledge. Furthermore, we support reuse of discovered knowledge to enable knowledge application (architecture evolution execution) that enables evolution-off-the-shelf in software architectures. Tool support facilitates the knowledge acquisition and knowledge application processes in the PatEvol framework.

peer-reviewed; Context: Architecture-centric software evolution (ACSE) enables changes in system’s structure and behaviour while maintaining a global view of the software to address evolution-centric trade-offs. The existing research and practices for ACSE primarily focus on design-time evolution and runtime adaptations to accommodate changing requirements in existing architectures. Objectives: We aim to identify, taxonomically classify and systematically compare the existing research focused on enabling or enhancing change reuse to support ACSE. Method: We conducted a systematic literature review (SLR) of 32 qualitatively selected studies, and taxonomically classified these studies based on solutions that enable i) empirical acquisition and ii) systematic application of architecture evolution-reuse knowledge to guide ACSE. Results: We identified six distinct research themes that support acquisition and application of architecture evolution-reuse knowledge. We investigated: a) how evolution-reuse knowledge is defined, classified and represented in the existing research to support ACSE, b) what are the existing methods, techniques, and solutions to support: b) empirical acquisition and c) systematic application of architecture evolution-reuse knowledge. Conclusions: Change patterns (34% of selected studies) represent a predominant solution...

No contexto do Desenvolvimento Baseado em Componentes(DBC), o elo de ligação entre desenvolvedores e consumidores de componentes de software são os repositórios de componentes, onde eles são adicionados por seus desenvolvedores e recuperados pelos integradores de sistemas. Considerando um cenário de evolução, onde componentes são modificados, são imprescindíveis modelos de evolução de componentes para definir uma abordagem sistemática de mudanças. Elas podem ocorrer, por exemplo, na especificação ou implementação de um componente e o repositório de componentes deve dar apoio à evolução uma vez que ela é parte inerente do processo de desenvolvimento de software. Contudo, assim como o software, modelos de evolução são modificados para acompanhar o desenvolvimento tecnológico e as necessidades de seus usuários. Além disso, diferentes produtores de componentes podem possuir modelos distintos. Este trabalho apresenta uma infra-estrutura de suporte à evolução em um repositório de componentes, para apoiar serviços de DBC, como a conversão de componentes para outros modelos de implementação, extração de metainformação de código-fonte de componentes, evolução de componentes e verificação de modelos de implementação de componentes.

A major question in evolutionary biology is whether ecological interactions among species affect the rate of evolution as organisms diversify. According to the ecological opportunity hypothesis, evolution occurs most rapidly in the absence of competition, and slows as competitors accumulate during diversification. I tested this hypothesis by measuring the rate of evolution in radiations of Anolis lizards on the four Greater Antilles islands. As predicted, anoles on these islands exhibited an early burst of evolution in traits important for habitat use, and the rate of evolution subsequently declined. It is less clear whether ecological opportunity has affected the rate of evolution in radiations of anoles in mainland South America and Central America. Although this relationship remains poorly understood, preliminary studies suggest that mainland anoles are at least as diverse in morphology and ecology as their island counterparts.; A major question in evolutionary biology is whether ecological interactions among species affect the rate of evolution as organisms diversify.

Behavior determines how organisms interact with their environment, and has long been posited as a pacemaker for evolution. The classical view is that novel behaviors expose organisms to new selective pressures, in turn "driving" evolution. Behavior can also restrain evolutionary change. Some behaviors, such as thermoregulation, help organisms maintain a constant selective environment, thus "inhibiting" evolution. This thesis seeks to understand the role of behavior in influencing the evolutionary process. In the first part, I test the hypothesis that the same behavior can simultaneously impede and impel evolution in different traits. I focus on the lizard, Anolis cybotes, from the Caribbean island of Hispaniola. Through a replicated field experiment I show that behavioral flexibility allows these lizards to maintain a constant body temperature in markedly different thermal habitats. I determine that this similarity in body temperatures is associated with physiological stasis, as the preferred temperature and heat tolerance are nearly identical among populations. I demonstrate that the behavioral change allowing lizards to maintain a constant body temperature involves a perch switch. Finally, I demonstrate that this shift in structural habitat use from trees at low elevation to rocks at high elevation in turn impels morphological evolution in traits associated with rock use...

The aim of this thesis is to investigate aspects of molecular evolution and enzyme engineering using the experimental evolution of Tobacco Etch Virus cysteine protease (TEV) as a model. I map key features of the local fitness landscape and characterise how they affect details of enzyme evolution. In order to investigate the evolution of core active site machinery, I mutated the nucleophile of TEV to serine. The differing chemical properties of oxygen and sulphur force the enzyme into a fitness valley with a >104-fold activity reduction. Nevertheless, directed evolution was able to recover function, resulting in an enzyme able to utilise either nucleophile. High-throughput screening and sequencing revealed how the array of possible beneficial mutations changes as the enzyme evolves. Potential adaptive mutations are abundant at each step along the evolutionary trajectory, enriched around the active site periphery. It is currently unclear how seemingly neutral mutations affect further adaptive evolution. I used high-throughput directed evolution to accumulate neutral variation in large, evolving enzyme populations and deep sequencing to reconstruct the complex evolutionary dynamics within the lineages. Specifically I was able to observe the emergence of robust enzymes with improved mutation tolerance whose descendants overtake later populations. Lastly...

In an ever-changing world, evolution is an essential process that may allow organisms to adapt to their environment through natural selection. All evolutionary processes act through a single fundamental medium: genetic variation. Polyploidy, or whole genome duplication, is a major mechanism for evolutionary change because it is both widespread across taxa and results in a proliferation of genetic material that evolution can act upon. The key questions addressed here are: (1) How does chromosome pairing during meiosis in allopolyploids affect the magnitude of genetic variation?, (2) How does the genome of polyploids evolve following formation, and what genetic mechanisms govern this evolution?, and (3) How does genetic and genomic evolution in polyploids affect phenotypic evolution? I use the shy monkeyflower, Mimulus sookensis, a tetraploid of hybrid origin between Mimulus guttatus and Mimulus nasutus, to address these focal questions. In order to develop a foundation to aid in interpretation of my findings, I first investigate the evolutionary history of M. sookensis. Chromosome counts establish that M. sookensis is indeed an allotetraploid, and a review of taxonomic literature reveals that this species is heretofore undescribed. By analysing the patterns of genetic variation at chloroplast and nuclear loci in M. guttatus...

How females establish in populations of cosexuals is central to understanding the evolution of gender dimorphism in angiosperms. Inbreeding avoidance hypotheses propose that females can establish and be maintained if cosexual fitness is reduced because they self-fertilize, and their progeny express inbreeding depression. Here we assess the role of inbreeding avoidance in maintaining sexual system variation in Wurmbea biglandulosa. We estimated costs of self-pollination, mating patterns, and inbreeding depression in gender monomorphic (cosexuals only) and dimorphic (males and females) populations. Costs of selfing, estimated from seed set of experimentally self- and crosspollinated flowers, were severe in both males and cosexuals (inbreeding depression, δ = 0.86). In a field experiment, intact males that could self produced fewer seeds than both emasculated males and females, whereas seed set of intact and emasculated cosexuals did not differ. Thus, pollinator-mediated selfing reduces fitness of males but not cosexuals under natural conditions. Outcrossing rates of males revealed substantial selfing (t = 0.68), whereas females and cosexuals were outcrossed (0.92 and 0.97). For males, progeny inbreeding coefficients exceeded parental coefficients (0.220 vs. 0.009)...

http://dx.doi.org/10.5007/2175-7968.2015v35n2p14The problem to be investigated in this article concerns the intricate tradition whereby translation has been historically affecting the evolution of human cultures; nevertheless, the general context of my investigation is not at all positioned in the sphere of biological or cultural repertoire as if they were delineated independently. I understand, on the contrary, that placing oneself in the position of that observer who gazes upon the abundant interaction between genes and cultural stimuli (not as enemies but as allies in the process of cultural evolution) would be much more effective than that. In this sense, my specific context regards the historical relevance of translation for the bridge proposed in “Cultural Transmission and Evolution” (Cavalli-Sforza, 2000) between genes, peoples, and languages to be effectively constructed – it seems of paramount importance to have a glimpse on how the process of translation has gradually been entering the game. The emergence of language in the social interactions of our ancestors has been decisive for the evolution of their (and consequently our) cultural environments, so decisive that trying to separate these realms (language and culture) is currently considered not only unfeasible but actually a complete utopia; hence my overall purpose to problematise even more such questionable division. Bearing in mind that my overall intention is to pay a careful look upon the twofold relationship between the evolution of language and that of culture...
