Quantifying the configurational complexity of biological systems in multivariate 'complexity space'.

An increasing number of evolutionary studies seek to quantify the morphological complexity of organisms, particularly those comprising serially homologous elements at different hierarchical levels of organization. Numerous operational frameworks have been proposed for doing this, but most focus on one or multiple conflated aspects of what is really a multidimensional concept. Here, we advocate the use of 'complexity spaces': multidimensional spaces defined by different vectors of complexity.

The ant genus are fascinating ants due to their distinctive morphology, ecology, and rarity. In this study, a comprehensive revision of in the Afrotropical region is presented, through a combination of morphological examination under the light microscope and three-dimensional (3D) cyber-taxonomy based on microtomography (micro-CT). Micro-CT based 3D surface models of all species were used for virtual morphological visualisation and examination.

Using next-generation sequencing data, the complete mitogenomes of six species from the genus were assembled. This study explores the mitochondrial genomes of species, among them the five species from the complex, comparing them with each other and with other species from Dolichoderinae subfamily to understand their evolutionary relationships and evolution. mitochondrial genomes contain the typical set of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and the A + T-rich control region.

Article Synopsis
- The study investigates phenotypic heterogeneity in patients with SCN8A variants, which causes a range of conditions from developmental delays to severe epileptic disorders.
- Researchers used machine learning to identify potential subgroups (U1-U3) based on developmental and seizure onset characteristics.
- Findings suggest that U1 and U2 have delayed and distinct seizure-onset patterns, while U3 patients experience simultaneous delays and seizures, impacting treatment responses and developmental outcomes.
