A genomic basis of vocal rhythm in birds

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Апрель 23, 2024

Abstract Vocal rhythm plays a fundamental role in sexual selection and species recognition birds, but little is known of its genetic basis due to the confounding effect vocal learning model systems. Uncovering could facilitate identifying genes potentially important speciation. Here we investigate genomic underpinnings non-learning Pogoniulus tinkerbirds using 135 individual whole genomes distributed across southern African hybrid zone. We find speed associated with two that are also affect human speech, Neurexin-1 Coenzyme Q8A. Models leveraging ancestry reveal these candidate loci impact rhythmic stability, trait linked motor performance which an indicator quality. Character displacement stability suggests possible reinforcement against hybridization, supported by evidence asymmetric assortative mating producing faster, more stable rhythms. Because omnipresent animal communication, identified here may shape birds other vertebrates.

Cross-species conservation in the regulation of parvalbumin by perineuronal nets

Frontiers in Neural Circuits, Год журнала: 2023, Номер 17

Опубликована: Дек. 19, 2023

Parvalbumin (PV) neurons play an integral role in regulating neural dynamics and plasticity. Therefore, understanding the factors that regulate PV expression is important for revealing modulators of brain function. While contribution to processes has been studied mammals, relatively little known about function non-mammalian species, discerning similarities regulation across species can provide insight into evolutionary conservation neurons. Here we investigated affect abundance sensory motor circuits songbirds rodents. In particular, examined degree which perineuronal nets (PNNs), extracellular matrices preferentially surround neurons, modulate as well how relationship between PNN differs areas changes over development. We generally found cortical are surrounded by PNNs (PV+PNN neurons) more enriched with than without (PV-PNN both rodents songbirds. Interestingly, vocal portion basal ganglia (Area X) differed from other areas, PV+PNN having lower compared PV-PNN These relationships remained consistent development songbird brain. Finally, discovered a causal because degradation led diminution findings reveal conserved cortices suggest could plasticity similar ways

Evolution of human language: duetting as part of prosociality and cognition

Frontiers in Ecology and Evolution, Год журнала: 2023, Номер 11

Опубликована: Июнь 16, 2023

The evolution of human language is a topic that has received undiminished attention. Numerous hypotheses for the origin have been proposed, including gestural communication found specifically among apes. This study advances hypothesis evolution, development, three-pronged: prosocial, cognitive, and collaborative. Duetting turn-taking in primates are used as pivotal examples how bonding leads to joint action collaboration. It points out such vocal behavior itself may be crucial precursor sense it explicitly focused on conspecific. Some current acknowledged duetting an important perceptual behavioral example synchronicity. forms synchronized behavior, duetting, dance, or even shared song, were perhaps evolutionary steps preceding language. signifies more than that, however, because observable significant cognitive investment signals attention toward partner. also affect cognition would needed precede any form signs affiliation grooming. Hence, this study, asking what terms, takes multidisciplinary multimodal approach suggest affective speech, chief which prosociality. Prosociality, attitude awareness another, friend partner whom one can do favors help, model collaboration cooperation, increased cognition.
