Disability in ecology & evolutionary biology.

With the blossoming of evolutionary developmental biology and evolutionary genomics following on the heels of the recent molecular revolution in evolutionary biology, the field is arguably expansive and integrative than ever. This growth has infused an air of excitement and anticipation into the discipline, as it appears to be on the verge of providing long-awaited answers to questions such as the structure of the tree of life, the origin of body plans, the genetic changes that underlie speciation, and the genetic basis of those traits that make us uniquely human (Avise 2003; Coyne and Orr 2004; Carroll 2005; The Chimpanzee Sequencing and Analysis Consortium 2005). At the same time, the fact that the pageantry of research in evolutionary biology is so diverse presents vexing questions for those of us faced with teaching undergraduate courses in evolutionary biology: how much of this vast discipline should we attempt to cover in a single course, and what is the best way to organize the material? The question of how much to cover is certainly not unique to evolutionary biology. Indeed, recent examples of streamlined textbooks for other survey courses such as ecology (e.g., Molles 2005), genetics (e.g., Hartl and Jones 2006), and general biology (e.g., Cain et al. 2006), suggests a growing sense that biology students in general may be best served under a less is more model of education. It is debatable whether this trend is motivated by the impracticalities of squeezing a rapidly expanding discipline into a single course, or by the reality of facing students who are poorly prepared for college science courses. However, one additional contributing factor is certain; most students in an upper level survey course in biology have no intention of pursuing a career in that biological subdiscipline. Thus, only a small fraction of students in such a course hunger for the subtle nuances of the field. As instructors, it is clear that these self-motivated students do not present our greatest educational challenge. Rather, our challenge in survey courses, including evolutionary biology, is in helping the uninspired majority learn both the central concepts and the ways of approaching questions in the major fields in biology. Given that challenge, it is difficult to argue against the less-is-more philosophy. Ironically though, it is probably safe to say that the majority of those who currently teach undergraduate courses in evolutionary biology cut their eye teeth while chewing (figuratively, one hopes) on the famously dense, exhaustively integrative, and encyclopedic Evolutionary Biology (Futuyma 1979, and subsequent editions). But while such a textbook provided abundant inspiration for students destined to become evolutionary biologists, its very strengths made it a

<p>This paper will analyze the theory of human evolution that developed in the West and the theory of human evolution explained in the Qur'an with an interpretive approach. The method used in this writing is to use qualitative methods sourced from sharing books related to the above problems. The approach to the method of interpretation of the Qur'an uses thematic methods, because this method can examine contemporary problems. The theory of evolution began to be studied and debated in the 6th century BC, Diwali by the Greek philosophers Anaximander, Empedocles, Lucretius, the same opinion was also expressed by the Arab biologist Al Jahiz, the Persian philosopher Ibn Miskawaih, the Ikhwan As-Shafa, and the Chinese philosopher Zhuangzi. Furthermore, the theory of evolution was published by an English scientist named Charles Darwin, the results of his research on evolution, especially human evolution, explained that the theory of evolution was not created by God but stood alone. This opinion caused debate among scientists and religionists, especially Islam, rejected because it contradicted the Qur'an.</p>

Responses to the body esteem scale (Franzoi & Shields, 1984) and multiple regression were used to determine if evolutionary biological theory is relevant to an understanding of self‐perceived physical and sexual attractiveness and self‐esteem and to determine if physical and sexual attractiveness are the same construct. It was hypothesized that regression models of physical and sexual attractiveness would differ within and across sex groups and that models of self‐esteem would differ across sex groups in accordance with evolutionary theory. These hypotheses were supported. Attributes of the body related to fecundity and successful mothering characteristics predicted for women and attributes of the body related to strength and dominance predicted for men. In addition, attributes of the body dealing with sexual maturity were stronger predictors of sexual attractiveness. Physical and sexual attractiveness are not the same constructs. This research indicates that evolutionary bological theory can provide relevant insight for an understanding of self‐perceived attractiveness and self‐esteem.

Hayek's The Sensory Order contains a physicalistic identity theory of the mind. Popper criticized it, saying that it could not explain the higher func- tions of language. Hayek took up that challenge in a manuscript but failed to refute Popper's arguments. Drawing upon the same manuscript, Hayek developed a theory of behavioural rules and cultural evolution. Despite his criticism of the theory of mind on which this evolutionary theory was based, Popper adopted Hayek's idea of group selection. He transformed it into a theory of the selective power of ecological niches. This became a central element of Popper's theory of evolution. The chapter traces the influence Popper and Hayek had on each other in the fields of the philosophy of mind and evolutionary theory. This is documented, inter alia, by their correspondence. Popper's theory of evolution, which is based on his dualistic theory of mind, is presented in its various stages of development The chapter concludes with a possible application of that evolutionary theory, some thoughts about David Hume as the source of the differences between Popper and Hayek, and on the possible impact Popper's criticism had on Hayek's role in artificial intelligence.

The purpose of writing this article is an attempt to uncover the concept of the missing link on human origins (the theory of evolution). Researchers want to stimulate the views of the Alpha generation to have another view, we know that most of the present generation still believes in the origin of living things from apes. The method used is the literature review method, the study is carried out on journals, books and other sources that are relevant and can be guaranteed its validity. Search results and studies, the authors found the concept if this theory has actually been questioned since the development of science in ancient Rome and Greece. Broadly speaking, this theory states that living things that exist in the world up to now are the result of the development of creatures that have existed before, both concerning structure and function, hereditary from generation to generation. Thus, the change which is the result of development takes place in a very long time, that is, millions of years along with the evolution of the universe. This theory is not entirely wrong, the problem is that the theory is only a theory that is not strengthened by physical evidence so that Darwin's theory is widely doubted from various circles. With the concept of Missing Link is one proof that humans do not originate from apes. This is due to the fact that no transitional creatures have been discovered from any changes that occur between species. In conclusion, the concept of the missing link becomes a reference to stimulate the generation of alpha in understanding the concept of evolution put forward by Darwin and refutes the process of the origin of man himself put forward in Darwin's theory of evolution. Key words: Missing Link, Stimulate, Theory of Human Evolution.

Hayek’s theory of cultural evolution has always generated controversy. Interest in Hayek’s theory, and others’ analysis and criticism of it, has been rising of late. This volume urges a reconsideration of Hayeks’ theory of evolution and aims to explore the relevance of Hayek’s theory for its own sake and for evolutionary economics more generally.

The topic of this thesis is the analysis of the evolution of software components. In order to track the evolution of software components, one needs to collect the evolution information of each component. This information is stored in the version control system (VCS) of the project—the repository of the history of events happening throughout the project’s lifetime. By using software archive mining techniques one can extract and leverage this information. The main contribution of this thesis is the introduction of evolution usage trends and evolution change patterns. The raw information about the occurrences of each component is stored in the VCS of the project. By organizing it in evolution trends and patterns, we are able to draw conclusions and issue recommendations concerning each individual component and the project as a whole.

Many scientists and philosophers of science are troubled by the relative isolation of developmental from evolutionary biology. Reconciling the science of development with the science of heredity preoccupied a minority of biologists for much of the twentieth century, but these efforts were not corporately successful. Mainly in the past fifteen years, however, these previously dispersed integrating programmes have been themselves synthesized and so reinvigorated. Two of these more recent synthesizing endeavours are evolutionary developmental biology (EDB, or "evo-devo") and developmental systems theory (DST). While the former is a bourgeoning and scientifically well-respected biological discipline, the same cannot be said of DST, which is virtually unknown among biologists. In this review, we provide overviews of DST and EDB, summarize their key tenets, examine how they relate to one another and to the study of epigenetics, and survey the impact that DST and EDB have had (and in future should have) on biological theory and practice.

Evolutionary biology is currently experiencing an emergence of several research topics that transcend the boundaries of the Modern Synthesis, which was the last major conceptual integration in evolutionary biology [1]. The Modern Synthesis used the concepts of population genetics to integrate Mendelian genetics with evolution by natural selection [2]. Pigliucci [3, and citations within] identified several major areas of innovation that transcend the Modern Synthesis: epigenetics, evolvability, phenotypic plasticity, evolution on adaptive landscapes, evolutionary developmental biology, and systems biology. Integrating these new ideas with the Modern Synthesis will form a new conceptual framework of evolution, which they termed the Extended Synthesis, as it will extend, rather than refute, the Modern Synthesis [3]. This subject has been the focus of much recent work, and an excellent description is provided in the book Evolution—The Extended Synthesis [2].

The question of vertebrate head segmentation has become one of the central issues in Evolutionary Developmental Biology. Beginning as a theory based in comparative anatomy, a segmental theory of the head has been adopted and further developed by comparative embryologists. With the use of molecular and cellular biology, and in particular analyses of the Hox gene complex, the question has been addressed at new levels, but it remains unresolved. In this review, vertebrate head segmentation is reevaluated, by introducing findings from experimental embryology and evolutionary biology. Developmental biology has shown that pattern is generated through hierarchically organized and causally linked series of events. The question of head segmentation can be viewed as a question of generative constraint, that is whether segmentation in the head is imposed by underlying segmental patterns, as it is in the trunk. In this respect, amphioxus appears to be segmented along the entire anteroposterior axis, with myotomes and peripheral nerves repeating with the same rhythm (somitomerism). Similarly, in the vertebrate trunk, the segmental patterns shared by myotomes, peripheral nerves and vertebrae are derived from the somites. However, in the head of vertebrates there is no such mesodermal pattern, although neuromerism and branchiomerism do indicate the presence of constraints derived from rhombomeres and pharyngeal pouches, respectively. These data fit better the concept of dual metamerism of the vertebrate body proposed by Romer (1972), than the traditional head cavity-based segmental model by Goodrich (1930).

The question of complexity in biological systems is recurrent in evolutionary biology and is central in complex systems science for obvious reasons. But this question is surprisingly overlooked by evolutionary systems biology. This comes unexpected given the roots of systems biology in complex systems science but also given that a proper understanding of the origin and evolution of complexity would provide clues for a better understanding of extant biological systems. In this chapter, we will explore the links between evolutionary systems biology and biological systems complexity, in terms of concepts, tools and results. In particular, we will show how complex models can be used to explore this question and show that complexity can spontaneously accumulate even in simple conditions owing to a “complexity ratchet” fuelled by sign epistasis.

Reports the APA Presidential address delivered at the Chicago convention, August 1975. Urban humanity is considered as a product of both biological and social evolution. Evolutionary genetics shows that when there is genetic competition among the cooperators (as for humans but not for the social insects), great limitations are placed upon the degree of socially useful, individually self-sacrificial altruism that biological evolution can produce. Human urban social complexity is a product of social evolution and has had to counter with inhibitory moral norms the biological selfishness which genetic competition has continually selected. Because the issues are so complex and the available data are so uncompelling, all of this should be interpreted more as a challenge to an important new area for psychological research than as established conclusions. It is emphasized, however, that these are important issues to which psychology should give much greater attention, and that scientific reasons exist for believing that there can be profound system wisdom in the belief systems our social tradition has provided us with.

Cepheid masses obtained from pulsation theory are almost always less than those derived from observed luminosities and the no-mass-loss stellar evolution theory mass-luminosity relation. This may indicate mass loss in the red giant region. However, evolution theory indicates that more than ten percent mass loss will prevent the blue loops that move most of the stars into the Cepheid pulsation instability strip. The mass anomaly problem is about thirty percent for the long period (> 15 days) Cepheids with observed Baade-Wesselink method radii and for those with bumps in their light and velocity curves (5.5 - 13 day periods). Chemically homogeneous models produce the correct bump phases only with lower than evolution theory masses. The mass anomaly is a factor of three or four for the double mode Cepheids and AC Andromedae, the only triple mode Cepheid. The long standing problem is to reconcile the differing masses obtained from evolution and pulsation theories.

Darwin's theory of evolution continues to be a source of contention for academics concerned with the main issues of Islam and science in the twentieth century. As such, this research seeks to elicit perspectives from Islamic scholarly figures such as Seyyed Hossein Nasr, Zaghloul Al-Najjar, and Nidhal Guessoum. The three figures have varying perspectives on Darwin's theory of evolution. This divergent interpretation of Darwin's theory of evolution demonstrates that the debate on Islam and science did not totally result in the merger of the two, as all Muslim scholars agreed. This research employs Michel Foucault's archaeology and genealogy theories to examine the growth of Darwin's theory of evolution in the Islamic world, as symbolized by the three thinking figures. The findings indicated that Nasr expressly rejected Darwin's theory of evolution, which had been subjected to scientific and philosophical scrutiny. Al-Najjar says that the attitude of rejection and general acceptance of evolution theory is incorrect. By contrast, Guessoum views Darwin's theory of evolution as a factual truth that must be understood through the lens of Islam in order to generate theistic conceptions of evolution.

In his divisions of science, Peirce placed pedagogy in the branch of practical sciences. This means that the profession of teaching can only be meliorated by experience, through practice. However, I argue that a holistic look at Peirce’s semiotics reveals an implicit philosophy of education. The key lies in understanding his account of experience in the context of his theory of evolution. By experience Peirce meant semiosis (action of signs), not the modern empirical notion of experience. The sign, unlike an idea (purely mental entity) does not belong strictly to mental or non-mental phenomena. Experience is a characteristic of the Universe (CP 5.448), understood as a physiology of arguments (Stjernfelt 2007). According to Peirce’s taxonomy of signs, learning is the evolution of signification from the Icon sign type to the Argument sign type, being the Universe’s way of discovering itself through life forms. The Argument sign type is a result of agapasm, evolution due to creative love (CP 6.302). The paper explains how Peirce’s theory of agapistic evolution underpins an educational paradigm.
