Geologists have found an historical panorama carved into the form of a river beneath the East Antarctic ice sheet

Jamieson et al. discover an extensive relic pre-glacial landscape preserved beneath the central East Antarctic Ice Sheet despite millions of years of ice cover. Image credit: Jamieson et al., doi: 10.1038/s41467-023-42152-2.

Geologists from Durham College and elsewhere have found a panorama that seems to have been formed by rivers at the least 14 million years in the past and even perhaps earlier than the preliminary progress of East Antarctic ice about 34 million years in the past. jamison et al.

A brand new DNA examine sheds mild on diving conduct in anglers

Understanding the genetic basis of convergence at broad phylogenetic scales remains a key challenge in biology. Kingfishers are a cosmopolitan bird radiation with diverse colors, diets, and feeding behaviors -- including the archetypal plunge-dive into water. Given the sensory and locomotor challenges associated with air-water transitions, kingfishers offer a powerful opportunity to explore the effects of convergent behaviors on the evolution of genomes and phenotypes, as well as direct comparisons between continental and island lineages. Eliason et al. use whole-genome sequencing of 30 diverse kingfisher species to identify the genomic signatures associated with convergent feeding behaviors. Image credit: Robert Balog.

In new analysis, ornithologists from the Subject Museum and elsewhere have analyzed the whole genomes of 30 completely different kingfisher species to establish genomic signatures related to convergent feeding behaviors and the power to dive with out struggling mind harm. Understanding the genetic foundation of convergence on broad evolutionary scales stays a significant problem in … Read more
