The progress of science is influenced substantially by social behaviour of and social interactions within the scientific community. Similar to innovations in primate groups, the social acceptance of an innovation depends not only upon the relevance of the innovation but also on the social dominance and connectedness of the innovator. There are a number of parallels between many well-known phenomena in behavioural evolution and various behavioural traits observed in the scientific community. It would be useful, therefore, to use principles of behavioural evolution as hypotheses to study the social behaviour of the scientific community...

Religion has been a widely present feature of human beings. This review explores developments in the evolutionary cognitive psychology of religion and provides critical evaluation of the different theoretical positions. Generally scholars have either believed religion is adaptive, a by-product of adaptive psychological features or maladaptive and varying amounts of empirical evidence supports each position. The adaptive position has generated the costly signalling theory of religious ritual and the group selection theory...

This short essay is based on a lecture that I gave at short notice on a subject in which I am by no means an expert. The combination of lack of expertise and time for preparation, created an unexpectedly unique opportunity for thinking outside the box. I decided not to try to read up (as there was no time in any case) but instead to organize the little that I already knew about cultural evolution in a systematic schema-I attempted to create a scaffolding, on which I could hang everything I knew about cultural evolution, and hopefully, everything I might ever discover about cultural evolution in the future...

Gupta et al., in their article in this issue ('Niche construction in evolutionary theory: the construction of an academic niche?'. doi:10.1007/s12041-017-0787-6), lament 'serious problems with the way science is being done' and suggest that 'niche construction theory exemplifies this state of affairs.' However, their aggressively confrontational but superficial critique of niche construction theory (NCT) only contributes to these problems by attacking claims that NCT does not make. This is unfortunate, as their poor scholarship has done a disservice to the evolutionary biology community through propagating misinformation...

Symbiosis is a process that can generate evolutionary novelties and can extend the phenotypic niche space of organisms. Symbionts can act together with their hosts to co-construct host organs, within which symbionts are housed. Once established within hosts, symbionts can also influence various aspects of host phenotype, such as resource acquisition, protection from predation by acquisition of toxicity, as well as behaviour. Once symbiosis is established, its fidelity between generations must be ensured. Hosts evolve various mechanisms to screen unwanted symbionts and to facilitate faithful transmission of mutualistic partners between generations...

While much of our understanding of genetic inheritance is based on the genome of the organism, it is becoming clear that there is an ample amount of epigenetic inheritance, which though reversible, escapes erasing process during gametogenesis and goes on to the next generation. Several examples of transgenerational inheritance of epigenetic features with potential impact on embryonic development and subsequent adult life have come to light. In placental mammals, the placenta is an additional route for epigenetic information flow...

When two lineages derived from a common ancestor become reproductively isolated (e.g. Neurospora crassa and N. tetrasperma), genes that have undergone mutation and adaptive evolution in one lineage can potentially become dysfunctional when transferred into the other, since other genes have undergone mutation and evolution in the second lineage, and the derived alleles were never 'tested' together before hybrid formation. Bateson (1909), Dobzhansky (1936), and Muller (1942) recognized that incompatibility between the derived alleles could potentially make the hybrid lethal, sterile, or display some other detriment...

The field of epigenetics has grown explosively in the past two decades or so. As currently defined, epigenetics deals with heritable, metastable and usually reversible changes that do not involve alterations in DNA sequence, but alter the way that information encoded inDNAis utilized.The bulk of current research in epigenetics concerns itself with mitotically inherited epigenetic processes underlying development or responses to environmental cues (as well as the role of mis-regulation or dys-regulation of such processes in disease and ageing), i...

Ramray Bhat, Dharma Pally
The term complexity means several things to biologists.When qualifying morphological phenotype, on the one hand, it is used to signify the sheer complicatedness of living systems, especially as a result of the multicomponent aspect of biological form. On the other hand, it has been used to represent the intricate nature of the connections between constituents that make up form: a more process-based explanation. In the context of evolutionary arguments, complexity has been defined, in a quantifiable fashion, as the amount of information, an informatic template such as a sequence of nucleotides or amino acids stores about its environment...

The history of ecology and evolutionary biology is rife with attempts to define and delimit species. However, there has been confusion between concepts and criteria, which has led to discussion, debate, and conflict, eventually leading to lack of consistency in delimitation. Here, we provide a broad review of species concepts, a clarification of category versus concept, an account of the general lineage concept (GLC), and finally a way forward for species discovery and delimitation. Historically, species were considered as varieties bound together by reproduction...

An analysis has been performed on implications existing between the presence/absence of the evolutionary stage of the prokaryote, that is to say, the presence/absence of common characteristics between archaea and bacteria, and the monophyletic/polyphyletic origin of genes of proteins. Thereafter, a theorem stating that: 'the polyphyletic origin of proteins would imply the absence of common characteristics between bacteria and archaea and therefore the lack of the evolutionary stage of the prokaryote, and vice versa that the indefinable prokaryote stage implies a polyphyletic origin of proteins', has been made and validated...

Autosomal dominant Alport syndrome (ADAS) accounts for 5% of all cases of Alport syndrome (AS), a primary basement membrane disorder arising from mutations in genes encoding the type IV collagen protein family.Mutations in COL4A3 and COL4A4 genes were reported to be associated with ADAS. In this study, clinical data in a large consanguineous family with seven affected members were reviewed, and genomic DNA was extracted. For mutation screening, all exons of COL4A3 and COL4A4 genes were polymerase chain reaction-amplified and direct sequenced from genomic DNA, and the mutations were analyzed by comparing with members in this family, 100 ethnicitymatched controls and the sequence of COL4A3 and COL4A4 genes from GenBank...

Autosomal recessive primary microcephaly is a rare genetic disorder that is characterized by reduced head circumference and a varying degree of intellectual disability. Genetic studies on consanguineous families with primary microcephaly have identified 15 (MCPH) causative genes that include MCPH1, WDR62, CDK5RAP2, CASC5, ASPM, CENPJ, STIL, CEP135, CEP152, ZNF335, PHC1, CDK6, CENPE, SASS6 MFSD2A ANKLE2 and CIT (Khan et al. 2014; Yamamoto et al. 2014; Alakbarzade et al. 2015;Morris-Rosendahl and Kaindl 2015; Basit et al...

The blue-crested lizard, Calotes mystaceus Duméril & Bibron, 1837, is listed as a protected wild animal in Thailand. Its population is likely to be dramatically reduced due to massive hunting in several areas in this country. Basic information on its population genetics is therefore needed to facilitate its conservation. Thus, in this study we investigated the mitochondrial cytochrome c oxidase subunit 1 (CO1) sequence variation of 238 individualC.mystaceus from 42 different geographical localities of the north, west, central, east and northeast regions of Thailand...
