Undergraduates commonly harbor alternate conceptions about evolutionary biology; these alternate conceptions often persist, even after intensive instruction, and may influence acceptance of evolution. We interviewed undergraduates to explore their alternate conceptions about macroevolutionary patterns and designed a 2-h lesson plan to present evidence that life has evolved. We identified three alternate conceptions during our interviews: that newly derived traits would be more widespread in extant species than would be ancestral traits, that evolution proceeds solely by anagenesis, and that lineages must become more complex over time. We also attempted to measure changes in the alternate conceptions and levels of acceptance of evolutionary theory in biology majors and nonmajors after exposure to the lesson plan. The instrument used to assess understanding had flaws, but our results are suggestive of mixed effects: we found a reduction in the first alternate conception, no change in the second, and reinforcement of the third. We found a small, but significant, increase in undergraduate acceptance of evolutionary theory in two trials of the lesson plan (Cohen's d effect sizes of 0.51 and 0.19). These mixed results offer guidance on how to improve the lesson and show the potential of instructional approaches for influencing acceptance of evolution.

Proximate Causation

Evolutionary theory has been extended almost continually since the evolutionary synthesis (ES), but except for the much greater importance afforded genetic drift, the principal tenets of the ES have been strongly supported. Adaptations are attributable to the sorting of genetic variation by natural selection, which remains the only known cause of increase in fitness. Mutations are not adaptively directed, but as principal authors of the ES recognized, the material (structural) bases of biochemistry and development affect the variety of phenotypic variations that arise by mutation and recombination. Against this historical background, I analyse major propositions in the movement for an ‘extended evolutionary synthesis’. ‘Niche construction' is a new label for a wide variety of well-known phenomena, many of which have been extensively studied, but (as with every topic in evolutionary biology) some aspects may have been understudied. There is no reason to consider it a neglected ‘process’ of evolution. The proposition that phenotypic plasticity may engender new adaptive phenotypes that are later genetically assimilated or accommodated is theoretically plausible; it may be most likely when the new phenotype is not truly novel, but is instead a slight extension of a reaction norm already shaped by natural selection in similar environments. However, evolution in new environments often compensates for maladaptive plastic phenotypic responses. The union of population genetic theory with mechanistic understanding of developmental processes enables more complete understanding by joining ultimate and proximate causation; but the latter does not replace or invalidate the former. Newly discovered molecular phenomena have been easily accommodated in the past by elaborating orthodox evolutionary theory, and it appears that the same holds today for phenomena such as epigenetic inheritance. In several of these areas, empirical evidence is needed to evaluate enthusiastic speculation. Evolutionary theory will continue to be extended, but there is no sign that it requires emendation.

Bacterial Quorum

The term quorum sensing (QS) is used to describe the communication between bacterial cells, whereby a coordinated population response is controlled by diffusible molecules produced by individuals. QS has not only been described between cells of the same species (intraspecies), but also between species (interspecies) and between bacteria and higher organisms (inter-kingdom). The fact that QS-based communication appears to be widespread among microbes is strange, considering that explaining both cooperation and communication are two of the greatest problems in evolutionary biology. From an evolutionary perspective, intraspecies signalling can be explained using models such as kin selection, but when communication is described between species, it is more difficult to explain. It is probable that in many cases this involves QS molecules being used as ‘cues’ by other species as a guide to future action or as manipulating molecules whereby one species will ‘coerce’ a response from another. In these cases, the usage of QS molecules cannot be described as signalling. This review seeks to integrate the evolutionary literature on animal signalling with the microbiological literature on QS, and asks whether QS within bacteria is true signalling or whether these molecules are also used as cues or for the coercion of other cells.

The publication of ‘An Evolutionary Theory of Economic Change’ by Nelson and Winter has had a major impact on economics and related fields such as innovation and strategy. All of these fields have developed owing to recent re-examinations and extensions of evolutionary theory. A paradigm that underlies several studies in this tradition is the concept of neo-Darwinian evolution—the idea that the unit of the evolutionary process (e.g. a technological artefact) is subject to a dynamic of variation, selection, and retention leading to adaptation to a predefined function. This book refers to the frameworks of punctuated equilibrium, speciation, and exaptation, which, despite their significant influence in evolutionary biology, have been reflected only partially in evolutionary approaches to economics, innovation, and strategy. This chapter introduces the book’s aim to fill this gap, and outlines the approaches and perspectives of each of the chapters.

Evolutionary thinking has grown significantly and has had a profound impact on various fields such as economics, strategy, and technological innovation. An important paradigm that underlies the evolutionary theory of innovation is neo-Darwinian evolution. According to this paradigm, evolution is gradualist and is based on the mechanisms of variation, selection, and retention. Starting from the 1970s, new theoretical advancements in evolutionary biology have recognized the central role of punctuated equilibrium, speciation, and exaptation in evolution and of Woesian dynamics. However, despite their significant influence in evolutionary biology, these advancements have been reflected only partially in evolutionary approaches to economics, strategy, and technological innovation. This chapter reviews these advancements and explores their key implications for innovation, such as the role of serendipity and unpre-stateability leading to disequilibrium in economics systems, and the importance of adopting an option-based logic during the innovation process.

Inheritance Of Acquired Characteristics

The Russian scientific community welcomed Darwin’s evolutionary theory and made it a basis of research in a wide range of biological sciences. Russian evolutionary studies in embryology, paleontology, microbiology and pathology attracted international attention. The vast scope of Darwin’s popularity in Russia was dramatically manifested in 1909, on the occasion of the national celebration of the 100th anniversary of the birth of the great English scientist and the 50th anniversary of the publication of The Origin of Species. All universities, naturalist societies, and many newspapers and popular journals took part in the celebration, which produced a hundred praiseful publications on Darwinian themes. University philosophers, steeped in metaphysical idealism and spiritualism, linked Darwinism to what they called ‘modern scientific materialism’ and rejected it wholly. They were strongly predisposed to welcome modern revivals of metaphysical vitalism. Freelance philosophers, usually associated with heterodox ideological movements and influenced by Auguste Comte’s positivism or various modern neopositivist and Neo-Kantian currents, credited Darwinism with making science a major topic of modern philosophy. A new discipline, known as ‘scientific philosophy’, rapidly developing in the West, made its first appearance in Russia. In the Soviet Union, Darwin’s evolutionary theory followed a course of cataclysmic ruptures. During the 1920s, Soviet scientists made significant contributions to the study of the role of the genetic environment in biological evolution and helped set the stage for an evolutionary synthesis of Darwinism and genetics. The Stalinist era (1929–53) marked a drastic departure from the prevalent currents in evolutionary biology. It was dominated by the rise of Lysenkoism, a pseudo-science identified as ‘creative Darwinism’, and was guided by a diluted version of the Lamarckian idea of evolution as a product of the inheritance of acquired characteristics. Lysenkoism rejected the Darwinian conception of natural selection, downgraded the role of physico-chemical analysis in biology, and paid no attention to molecular biology. In 1948 Lysenkoism was officially recognized as the Marxist theory of evolution. Under Lysenko’s influence, genetics was proclaimed a ‘bourgeois science’ and was made illegal. The downfall of Lysenkoism in 1964 brought the re-establishment of genetics, a full-scale return to true Darwinism, and a re-intensified interest in ‘evolutionary synthesis’.

Abstract Background Mental health has been conceptualised by the World Health Organisation (WHO) as not just the absence of illness but as a state of well-being in which the individual can cope with normal stresses of life, work productively and fruitfully, and make a contribution to the community. To achieve this or to explain it to the stakeholders, a doctor needs to be well versed with the normal functioning of the human mind. Homoeopathic doctors must have this knowledge to help them understand and treat their patients or advise prevention. Lack of this knowledge in the undergraduate years fails to suitably equip them, thereby hampering their own growth and clinical functions. These papers (in two parts) will deal with the teaching of basic and applied psychology and abnormal psychology and psychiatry to homoeopathic undergraduates. Aim The main aim of this study is to teach homoeopathic undergraduate students the basic psychological concepts required for understanding human behaviour through cased based presentations Methodology Plan of teaching psychology to undergraduate students with a case-based approach was formulated by the Psychiatric Department of Dr. M.L. Dhawale Homoeopathic Institute (MLDMHI), Palghar. Postgraduate students prepared topics with the help of a lesson plan template under the guidance of faculty. Peer evaluation along with student feedback helped to gauge the impact of the lectures and to design improvements. Results Thirteen topics, one each week, covered the assigned portion for basic psychology. Reports of around 30 students and 2 lecturers for each lecture over 3 years were evaluated. These indicated satisfaction with contents and desire to have more such lectures. Multiple choice questions post lectures allowed to identify the changes in knowledge and interest of students in the subject. Discussion Basic and comprehensive knowledge of psychology will allow students/physicians to look at the cases not only from the view point of physical antecedents but also from a more holistic and comprehensive point of view. Conclusion Educational ethos demands the incorporation of case-based teaching in undergraduates especially in the teaching of psychology, to expose the shades of normal and abnormal states of mind through case-based teachings.

Charles Darwin has had an extraordinary impact on many aspects of human affairs apart from revolutionizing biology. On the 200th anniversary of his birth, the Cambridge Darwin Festival in July 2009 celebrated these contributions to the humanities, philosophy and religion and the approach to medicine, economics and the social sciences. He is a man to revere. It is no discredit to him that the science of evolutionary biology should continue to evolve. In this article I shall consider some of the ways in which this has happened since his day.

Th. Dobzhansky played a special role in the reception and development of the “synthetic theory of evolution,” as well as in the establishment of scientific connections between Soviet and U.S. evolutionists, and first and foremost, geneticists. These connections greatly influenced the development of Soviet genetics, of evolutionary theory and evolutionary biology as a whole, and in particular the restoration of Soviet genetics in the late 1960s. A discussion of Dobzhansky’s correspondence and collaboration with colleagues in his native country, moreover, allows for an improved understanding of the complex and dramatic history of Soviet genetics and evolutionary theory. It also provides novel insights into the interactions between scientists and authorities in the Soviet Union (USSR).
