(A) Locations of 2,082 languages in the Ruhlen database. Phoneme inventory size of each language is indicated by the color bar. (B) For the Ruhlen phoneme–genome dataset, pairwise geographic distance matrices were projected along different axes (calculated at 1° intervals); within each region, the rotated axis of geographic distance that was most strongly associated (greatest Mantel r) with phonemic distance (black arrows) and genetic distance (gray dashed arrows) is shown. Thinner arrows (Europe, East Asia, South America) indicate nonsignificant associations. Black dots indicate population locations for the Ruhlen phoneme–genome dataset. With the exception of North America, axes of phonemic differentiation and genetic differentiation are similar in most regions (North America: 78° difference; other regions: mean difference 16°). https://images.squarespace-cdn.com/content/v1/55efb889e4b064e46225b4bf/1441953372729-J740FRUDFQ63H3HNH7J3/emberizid+paper+figure.png Research Signals of evolutionary history in a learned behavior: song reflects phylogeny in sparrows Song spectrograms and phylogenetic relationships. The genetic relationships between species are indicated by the phylogeny on the left, with the Spizella clade shown in blue, Zonotrichia in green, and Pipilo in yellow. An example song spectrogram for each species is shown on the right, with the red scale bar on each panel representing 0.2 seconds. https://images.squarespace-cdn.com/content/v1/55efb889e4b064e46225b4bf/1441868378267-TKV4C4XTHZXGSOAYSZ25/plos+one+CNC+figure.png Research Models of niche construction with selection and assortative mating Schematic of cultural niche construction. Cultural niche construction results in environmental variation, which may produce two distinct forms of feedback. Route 1: a cultural trait modifies selection pressures, which can induce further cultural change. Route 2: gene-culture coevolution, where a cultural trait changes selection pressures, causes population level genetic changes in response. Evolutionary outcomes from both route 1 and route 2 depend on the frequency of T (cultural or genetic) and N (cultural) traits in the population and the selection pressures they generate, here represented by si. https://images.squarespace-cdn.com/content/v1/55efb889e4b064e46225b4bf/1550786775921-BRFKQVNQMQ3VTJF7BH1W/Snyder+Creanza+Figure+2+resized+for+website.png Research Polygyny is linked to accelerated birdsong evolution but not to larger song repertoires Ancestral character estimation of polygyny and syllable repertoire. At the tips of the tree, monogamy is indicated by black circles and polygyny is indicated by white circles. At the nodes of the tree, bars indicate the results of an ancestral character estimation algorithm, with the black fraction of the bar indicating the percent likelihood that the ancestor at that node was monogamous. The colors along the branches of the tree indicate the estimated ancestral syllable repertoire size. The syllable repertoire sizes ranged from 1 to 2400 in these species and were log10 transformed for analysis. Asterisks indicate nodes that had less than 70% support across 1000 tree replicates; no node had less than 50% support on this tree. Monogamous and polygynous species did not have significantly different syllable repertoire sizes (PhylANOVA p = 0.250). Images representing taxa were used or modified from PhyloPic (http://phylopic.org).
