EVOLUTIONARY RISK OF HIGH HUME TECHNOLOGIES. Article 2. THE GENESIS AND MECHANISMS OF EVOLUTIONARY RISK

Sources of evolutionary risk for stable strategy of adaptive Homo sapiens are an imbalance of: (1) the intra-genomic co-evolution (intragenomic conflicts); (2) the gene-cultural co-evolution; (3) inter-cultural co-evolution; (4) techno-humanitarian balance; (5) inter-technological conflicts (technological traps). At least phenomenologically the components of the evolutionary risk are reversible, but in the aggregate they are in potentio irreversible destructive ones for biosocial, and cultural self-identity of Homo sapiens. When the actual evolution is the subject of a rationalist control and/or manipulation, the magnitude of the 4th and 5th components of the evolutionary risk reaches a level of existential significance

Haematopoietic chimerism expressivity in bovine heterosexual twins

The aim of the experiment was to study the haematopoietic chimerism in bovine heterosexual twins conceived through artificial insemination and post-embryo transfer. Both animal groups were revealed to have a wide individual range of variability for the expressivity of chimerism that varied from 0 to 96% of cells with the chromosomes of an opposite sex. The study also revealed the tendency towards increased frequency of cytogenetic anomalies in immigrant cells

Functional Insights into Genic Neighbourhood Organization of Helitron Transposons in Bos taurus Genomes

Transposable elements (TEs) represent well-known factors of genomic variability and evolution. TEs are important providers of regulatory elements that are able to significantly influence the architecture and expression of the host genome. Currently, of a special interest are the DNA transposons helitrons. They are supposed to be involved in horizontal transfer of genetic material between distant taxa and to dramatically impact the host genomes via phenomena of exon-shuffling and gene capture. Thereby, and due to their high level of polymorphism and relatively high frequency in the eukaryotic genomes, helitrons can be used as “anchors” for genome scanning of different breeds of farm animals aimed at revealing their “gene pool standards”. Currently, there are no comprehensive studies dedicated to helitrons and their interaction and impact on host genomic landscape in cattle (Bos taurus). Earlier we showed the possibility of using the 3’-end consensus sequence of Heligloria helitrons for estimation of consolidation of different cattle breeds via multilocus genotyping. In the present study, in order to investigate the context features of the DNA regions flanked by the inverted repeats of Heligloria helitrons fragments in Bos taurus genomes, we pyrosequenced such fragments (of about 550 bp in length) from three cattle breeds and analyzed the functional implications of the identified genes. Thus, here we provide an insight into the functional organization of the genic neighbourhood of helitron transposons in the genomes of different Bos taurus breeds and an attempt to understand possible consequences of such distribution of helitrons on these genome

EVOLUTIONARY RISK OF HIGH HUME TECHNOLOGIES. Article 3. EVOLUTIONARY SEMANTICS AND BIOETHICS

The co-evolutionary concept of three-modal stable evolutionary strategy of Homo sapiens is developed. The concept based on the principle of evolutionary complementarity of anthropogenesis: value of evolutionary risk and evolutionary path of human evolution are defined by descriptive (evolutionary efficiency) and creative-teleological (evolutionary correctness) parameters simultaneously, that cannot be instrumental reduced to other ones. Resulting volume of both parameters define the vectors of biological, social, cultural and techno-rationalistic human evolution by two gear mechanism — genetic and cultural co-evolution and techno-humanitarian balance. Explanatory model and methodology of evaluation of creatively teleological evolutionary risk component of NBIC technological complex is proposed. Integral part of the model is evolutionary semantics (time-varying semantic code, the compliance of the biological, socio-cultural and techno-rationalist adaptive modules of human stable evolutionary strategy)

Cohesive versus Flexible Evolution of Functional Modules in Eukaryotes

Although functionally related proteins can be reliably predicted from phylogenetic profiles, many functional modules do not seem to evolve cohesively according to case studies and systematic analyses in prokaryotes. In this study we quantify the extent of evolutionary cohesiveness of functional modules in eukaryotes and probe the biological and methodological factors influencing our estimates. We have collected various datasets of protein complexes and pathways in Saccheromyces cerevisiae. We define orthologous groups on 34 eukaryotic genomes and measure the extent of cohesive evolution of sets of orthologous groups of which members constitute a known complex or pathway. Within this framework it appears that most functional modules evolve flexibly rather than cohesively. Even after correcting for uncertain module definitions and potentially problematic orthologous groups, only 46% of pathways and complexes evolve more cohesively than random modules. This flexibility seems partly coupled to the nature of the functional module because biochemical pathways are generally more cohesively evolving than complexes

Tool-use learning by common marmosets (Callithrix jacchus)

One of the most critical and common features of tool use is that the tool essentially functions as a part of the body. This feature is likely rooted in biological features that are shared by tool users. To establish an ideal primate model to explore the neurobiological mechanisms supporting tool-use behaviours, we trained common marmosets, a small New World monkey species that is not usually associated with tool use, to use a rake-shaped tool to retrieve food. Five naive common marmosets were systematically trained to manipulate the tool using a 4-stage, step-by-step protocol. The relative positions of the tool and the food were manipulated, so that the marmosets were required to (1) pull the tool vertically, (2) move the tool horizontally, (3) make an arc to retrieve a food item located behind the tool and (4) retrieve the food item. We found considerable individual differences in tool-use technique; for example, one animal consistently used a unilateral hand movement for all of the steps, whereas the others (n = 4) used both hands to move the tool depending on the location of the food item. After extensive training, all of the marmosets could manipulate the rake-shaped tool, which is reported in this species for the first time. The common marmoset is thus a model primate for such studies. This study sets the stage for future research to examine the biological mechanisms underlying the cognitive ability of tool use at the molecular and genetic levels
