Long before mammals, birds, and flowering plants, Arthropleura moved through humid Carboniferous forests as a 2.5-meter terrestrial giant. Its anatomy, diet, ecosystem, and extinction reveal how radically Earth once operated.
Deinonychus transformed the public image of dinosaurs and helped launch a new era of paleontology. Discover what its sickle claw, agile anatomy, and possible connection to feathered dinosaurs reveal.
A tiny finger bone revealed the Denisovans, an otherwise nearly invisible human lineage whose DNA still shapes adaptation, immunity, and the genetic history of people across Asia and Oceania.
Sixty-six million years ago, an asteroid struck the Yucatán Peninsula and set off a chain of environmental disasters. Here is how the impact, volcanic stress, and ecological vulnerability combined to reshape life on Earth.
The asteroid that ended the age of non-avian dinosaurs did not erase the dinosaur lineage. Feathered theropods survived, evolved, and eventually became the more than 10,000 bird species living today.
Humanity’s story began in the aftermath of a mass extinction and unfolded through forests, changing climates, upright walking, technology, fire, culture, and encounters with other human lineages.
