Natural History
Maybe it was messier than we thought, some scientists now say. Big brains, long legs and long childhoods may have evolved piecemeal in different spots, in response to frequent swings in climate.
 
Passenger pigeons used to be the most abundant bird in North America. But hunters drove them to extinction, and by 1914, only one was left. A century later, that pigeon, named Martha, is on exhibit.
 
This bird likes livers, kidneys, entrails — anything it can pluck that's freshly dead. But what if you served it ... a painting?
 
Museums are filled with dead insects, birds, fish, mammals and reptiles meticulously gathered worldwide in the name of scientific discovery. But some researchers now say scientists should think twice.
 
A secretive, nocturnal species that lives on a remote island off the coast of Mexico had not been spotted since 1936. Scientists have concluded it is genetically distinct from mainland neighbors.
