The evolution of flightless birds
Based on an analysis of the genomes of more than a dozen flightless birds, including an extinct moa, a team led by Harvard researchers found that while different species show wide variety in the protein-coding portions of their genomes, they appear to turn to the same regulatory pathways when evolving flight loss.

Similar designs, 100 million years apart
A study found that both Rusingoryx atopocranion, a relative of the wildebeest, and hadrosaur dinosaurs evolved large bony domes on their foreheads, which were likely used as resonating chambers to warn of predators and communicate with others.
