Based on the analysis of the genomes of more than a dozen flightless birds, including an extinct moa, researchers found that while different species show wide variety in the protein-coding portions of their genome, they appear to turn to the same regulatory pathways when evolving flight loss.
Cross-referencing a decade of Google searches and citizen science observations, researchers have determined which of 621 North American bird species are currently the most popular and which characteristics of species drive human interest.
