According to a study released on Thursday, Sept. 19, 2019, North America’s skies are lonelier and quieter as nearly 3 billion fewer wild birds soar in the air than in 1970. Some of the most common and recognizable birds are taking the biggest hits, even though they are not near disappearing yet. The population of eastern meadowlarks has shriveled by more than three-quarters with the western meadowlark nearly as hard hit. (AP Photo/David Zalubowski, File)

From that, they concluded the woman was an artist involved in creating illuminated manuscripts, a task usually associated with monks. The find is considered the most direct evidence yet of a woman taking part in the making of high-quality illuminated manuscripts, the lavishly illustrated religious and secular texts of the Middle Ages. And it corroborates other findings that suggest female artisans were not as rare as previously thought. (Christina Warinner/Max Planck Institute for the Science of Human History via AP)
