Beautiful, creative work from @loganjames.bsky.social et al! doi.org/10.1101/2025...

1. Humans share sound preferences w animals (even insects!)
2. Musical experience predicts agreement w animals

"...our data indicate a more expansive shared ‘taste for the beautiful’"

Fig. 1. Humans and other animals share acoustic preferences (A) Each dot depicts the mean 3 and 95% confidence interval for human responses to a pair of stimuli. Above is a phylogenetic tree, with color depicting the average agreement between humans and the species across all stimulus pairs (teal colors depict agreement, brown colors disagreement). Right are all data pooled with the horizontal bar and whiskers depicting the mean ± 95% confidence interval across all stimuli. (B) There is a significant relationship between the strength of the preference within the animal studies (x-axis) and the percent of humans that agreed with animals (y-axis). Each dot depicts a pair of stimuli, and the trendline is a simple linear correlation ± SE. (C) Reaction times were significantly faster for trials when the participant selected the stimulus that was preferred by animals (dots and error bars depict the mean ± SE across all trials). Note that, for analysis, we used z-transformed square root values, which were back transformed for visualization. (D) Intra-rater agreement is above chance both for stimulus pairs with significant inter-rater agreement (right) as well as for pairs at chance inter-rater agreement (left). Each dot depicts the mean intra-rater agreement for a stimulus pair. For all panels, colors depict the four larger phylogenetic groups (insects, birds, mammals, and frogs). * p < 0.05

As if the plumage of birds-of-paradise wasn't already amazing enough, new research shows that males of most species are actually biofluorescent, meaning they absorb and re-emit light! #ornithology
Many birds-of-paradise species emit light through their plumage, study finds
