Convergent evolution of the genomes of marine mammals : Nature Genetics : Nature Publishing Group | Bioinformatics, Comparative Genomics and Molecular Evolution | Scoop.it
Andrew Foote and colleagues report the whole-genome sequences and de novo assemblies of three marine mammal species[mdash]the walrus, killer whale and manatee[mdash]and an improved bottlenose dolphin genome. Their comparative genomic analysis finds evidence of parallel evolution across the marine mammal genomes.

Arjen ten Have's insight:
We are bacteria, YOUR resistance is futile since we will exapt. Must be a scary episode of Star Trek. This makes a lot of sense, microbes do not have sex, hence they must transfer material otherwise. These kind of studies show us how vast and how fast resistance spreads. There is even no need for direct transfer, the community will solve it. Just like the Borg they simply exapt resistance. Yet another demonstation of the fact that adatation is meaningless in terms of evolution. It is exaptation of existing plasticity.

NMR Methods to Study Dynamic Allostery

NMR Methods to Study Dynamic Allostery | Bioinformatics, Comparative Genomics and Molecular Evolution | Scoop.it
Nuclear magnetic resonance (NMR) spectroscopy provides a unique toolbox of experimental probes for studying dynamic processes on a wide range of timescales, ranging from picoseconds to milliseconds and beyond. Along with NMR hardware developments, recent methodological advancements have enabled the characterization of allosteric proteins at unprecedented detail, revealing intriguing aspects of allosteric mechanisms and increasing the proportion of the conformational ensemble that can be observed by experiment. Here, we present an overview of NMR spectroscopic methods for characterizing equilibrium fluctuations in free and bound states of allosteric proteins that have been most influential in the field. By combining NMR experimental approaches with molecular simulations, atomistic-level descriptions of the mechanisms by which allosteric phenomena take place are now within reach.

System that replaces human intuition with algorithms outperforms human teams | Bioinformatics, Comparative Genomics and Molecular Evolution | Scoop.it
Big-data analysis consists of searching for buried patterns that have some kind of predictive power. But choosing which "features" of the data to analyze usually requires some human intuition. In a database containing, say, the beginning and end dates of various sales promotions and weekly profits, the crucial data may not be the dates themselves but the spans between them, or not the total profits but the averages across those spans.

Computational Modeling, Formal Analysis, and Tools for Systems Biology

Computational Modeling, Formal Analysis, and Tools for Systems Biology | Bioinformatics, Comparative Genomics and Molecular Evolution | Scoop.it
As the amount of biological data in the public domain grows, so does the range of modeling and analysis techniques employed in systems biology. In recent years, a number of theoretical computer science developments have enabled modeling methodology to keep pace. The growing interest in systems biology in executable models and their analysis has necessitated the borrowing of terms and methods from computer science, such as formal analysis, model checking, static analysis, and runtime verification. Here, we discuss the most important and exciting computational methods and tools currently available to systems biologists. We believe that a deeper understanding of the concepts and theory highlighted in this review will produce better software practice, improved investigation of complex biological processes, and even new ideas and better feedback into computer science.

The evolution of cooperation within the gut microbiota

Little is known about cooperative behaviour among the gut microbiota; here, limited cooperation is demonstrated for Bacteroides thetaiotaomicron, but Bacteroides ovatus is found to extracellularly digest a polysaccharide not for its own use, but to cooperatively feed other species such as Bacteroides vulgatus from which it receives return benefits.

Functional Implications of Human-Specific Changes in Great Ape microRNAs

Functional Implications of Human-Specific Changes in Great Ape microRNAs | Bioinformatics, Comparative Genomics and Molecular Evolution | Scoop.it
microRNAs are crucial post-transcriptional regulators of gene expression involved in a wide range of biological processes. Although microRNAs are highly conserved among species, the functional implications of existing lineage-specific changes and their role in determining differences between humans and other great apes have not been specifically addressed. We analyzed the recent evolutionary history of 1,595 human microRNAs by looking at their intra- and inter-species variation in great apes using high-coverage sequenced genomes of 82 individuals including gorillas, orangutans, bonobos, chimpanzees and humans. We explored the strength of purifying selection among microRNA regions and found that the seed and mature regions are under similar and stronger constraint than the precursor region. We further constructed a comprehensive catalogue of microRNA species-specific nucleotide substitutions among great apes and, for the first time, investigated the biological relevance that human-specific changes in microRNAs may have had in great ape evolution. Expression and functional analyses of four microRNAs (miR-299-3p, miR-503-3p, miR-508-3p and miR-541-3p) revealed that lineage-specific nucleotide substitutions and changes in the length of these microRNAs alter their expression as well as the repertoires of target genes and regulatory networks. We suggest that the studied molecular changes could have modified crucial microRNA functions shaping phenotypes that, ultimately, became human-specific. Our work provides a frame to study the impact that regulatory changes may have in the recent evolution of our species.
Arjen ten Have's insight:
The authors do not claim this was the trigger for speciation but IMO this does demonstrate how sympatric speciation can occur.

Fluctuation-Driven Neural Dynamics Reproduce Drosophila Locomotor Patterns

Fluctuation-Driven Neural Dynamics Reproduce  Drosophila  Locomotor Patterns | Bioinformatics, Comparative Genomics and Molecular Evolution | Scoop.it
Author Summary The brain is never quiet. Even in the absence of environmental cues, neurons receive and produce an ongoing barrage of fluctuating signals. These fluctuations are well studied in the sensory periphery but their potential influence on central circuits and behavior are unknown. In particular, activity fluctuations in action selection circuits—neural populations that drive an animal’s actions from moment to moment—may strongly influence behavior. To shed light on the influence of

Luckily we are not worms. Or are we? The message is that males prefer sex over a meal and that women prefer sustenance. In terms of evolution this does make sense.
