Two populations showed the same core pattern: adolescent giraffes most often associated with peers of their own sex, without simply collecting more companions.
Scientific commentary
Well-preserved skulls and an unusually complete skeleton placed a Spanish giraffid within a much wider evolutionary comparison.
Scientific commentary
Separate fossils preserved different parts of early Giraffa anatomy, allowing comparisons that tooth-only species could not provide.
Scientific commentary
The microbes that help digest leaves varied between feeding groups, but a first survey could not yet say how those differences changed digestion.
Scientific commentary
Tiny worms inside skin lesions offered a clue. Comparing their DNA with known parasites helped researchers ask a more precise question.
Scientific commentary
A return to a census last conducted in 1979–1980 found roughly half as many giraffes, with the sharpest loss in the park’s southern population.
