The Kokshaal racerunner, Eremchenko et Panfilov, 1999, together with other central Asian racerunner species, is included in the complex. In the present work, for the first time, the results of the analysis of historical mitochondrial DNA (barcode) are presented and the taxonomic status and preliminary phylogenetic relationships within the complex are specified. We present, for the first time, the results of the molecular analysis using historical DNA recovered from specimens of several species of this complex (paratypes of the Kokshaal racerunner and historical collections of the Kashgar racerunner from Kashgaria) using DNA barcoding.

The origins and prehistory of domestic sheep () are incompletely understood; to address this, we generated data from 118 ancient genomes spanning 12,000 years sampled from across Eurasia. Genomes from Central Türkiye ~8000 BCE are genetically proximal to the domestic origins of sheep but do not fully explain the ancestry of later populations, suggesting a mosaic of wild ancestries. Genomic signatures indicate selection by ancient herders for pigmentation patterns, hornedness, and growth rate.

To many in the scientific community, the 1975 Asilomar Conference on Recombinant DNA stands as a singular achievement. This experiment in governance seemed to demonstrate that citizens could trust scientists to anticipate their fields' risks and propose sensible ways to regulate themselves. Over the past half-century, similar efforts have been made to govern controversial areas of research, from geoengineering to artificial intelligence.

In this paper, I review archaeological evidence for shifting human-avian interactions. Many species of birds, altering their behavior in response to anthropogenic niche construction, experienced an increased encounter rate with humans. Intensification of this relationship led to management and domestication of some taxa.

Background: In this study, we present an in-depth analysis of the Eurasian minnow (Phoxinus phoxinus) genome, highlighting its genetic diversity, structural variations, and evolutionary adaptations. We generated an annotated haplotype-phased, chromosome-level genome assembly (2n = 50) by integrating high-fidelity (HiFi) long reads and chromosome conformation capture data (Hi-C).
Results: We achieved a haploid size of 940 megabase pairs (Mbp) for haplome 1 and 929 Mbp for haplome 2 with high scaffold N50 values of 36.

Here we reassess available evidence for the long-held misconception of amoebae possessing exceptionally large genomes. Traditionally, estimates relied on inaccurate methods like DNA weight measurements, leading to inflated sizes. These methods failed to account for contaminating DNA from prey, endosymbionts, and intrinsic genomic features like ribosomal operon amplification.
