Welcome back to the Abstract! Here are the studies this week that glimpsed a bygone world, caught an 80-foot fish, outshone the stars, and declared scientific independence. First, a mysterious group of extinct human relatives were probably not as advanced as once thought, a finding that sheds light on their possible lineage. Then: a gem from the paleontological lost-and-found, megaconstellations versus stellar constellations, and oh-say-can-you-see 250 years of American science history?
