Fossilfynd i Etiopien visar att tidiga människoarter samexisterade

Forskare har hittat fossila tänder i Etiopien som tyder på att tidig Homo och en okänd Australopithecus-art delade landskapet för mellan 2,6 och 2,8 miljoner år sedan. Upptäckten stärker bevisen för att människans evolution innefattade flera överlappande släktlinjer snarare än en enda rak utvecklingslinje.

Ett internationellt forskarlag som arbetade vid fyndplatsen Ledi Geraru har utvunnit 13 tänder från urgamla sediment. Dessa lämningar tillhör både den tidigaste kända Homo-arten och en distinkt Australopithecus-art som inte tidigare dokumenterats på platsen. Vulkaniska asklager ovanför och under fossilen möjliggjorde en precis datering genom fältspatkristaller.

Dinosaur tracks from 132 million years ago discovered near Knysna

25 april 2026 Rapporterad av AI

Scientists have uncovered more than two dozen dinosaur tracks dating back 132 million years in a small rock outcrop near Knysna, South Africa. These footprints, the youngest known in southern Africa, indicate dinosaurs persisted in the region into the early Cretaceous Period. The discovery challenges previous gaps in the local fossil record following ancient lava flows.
