Interesting πŸ“° @theguardian.com by @samanthsubramanian.bsky.social on non-neural cognition: www.theguardian.com/news/ng-inte...

Confronted with this polarizing debate, @philosobio.bsky.social & I wrote a balanced take on basal #cognition from an #evobio lens πŸ‘‡ link.springer.com/article/10.1... #HPS

Bodin, Morlon & @bperezlamarque.bsky.social reevaluated evidence for codiversification in mycorrhizal symbioses, finding that closely related plants often interact with closely related fungi, but their phylogenies do not match.

@marzena-marszalek.bsky.social et al. integrate WGS and RNAseq from 282 wild yeast strains, finding robust signals of nonsense-mediated mRNA decay but no clear evidence of transcriptional adaptation.

New genus and species of lungfishes from the Famennian of Latvia - Jumisodus latus, named after the god "Jumis" from old Baltic mythology.

Letcher et al. reveal how Mesorhabditis nematodes evolved a new Y chromosome from sexual ancestors in species that transitioned into autopseudogamy - females produce clonal females plus rare males that are needed for fertilization.

MBE | Emergence and stabilization of a neo-Y chromosome in nematode species with rare males

In this work, Letcher et al. study the sex chromosomes of nematodes that have transitioned away from sexuality, into a mode of reproduction where most individuals (~90%) are females. Rare males (~10%) are also found and produce sperm that is necessary for fertilisation of female eggs. However in most cases, the paternal DNA is discarded, and clonal daughters are produced. Surprisingly, in the rare cases where the paternal DNA is used, only males are ever produced.

The team found that these rare males carry a new Y chromosome that evolved specifically with this strange mode of reproduction. This Y chromosome carries genes likely to make these males fitter, and carries factors that enable sperm carrying the Y to preferentially fertilise female eggs. In the long run, these factors have probably stabilised the Y chromosome in these populations.

Like thylacines? Of course you do.
A little thread on some recent research I was part of with @weisbeckerbblab.bsky.social here 🧡‡️

Interesting hypothesis of firelight in the campfire as the modulator of the humans speech in the frequency space. Coevolution of biotic-cultural traits with the (local) fabricated environment.
