科学家们提出恐龙起源于今天的亚马逊和撒哈拉, 挑战早期的理论。 Scientists propose dinosaurs originated in today's Amazon and Sahara, challenging earlier theories.

研究人员现在认为恐龙起源于赤道附近的炎热干燥地区,即今天位于亚马逊和撒哈拉的贡德瓦纳地区。 Researchers now suggest dinosaurs originated in hot, dry regions near the equator, in areas of Gondwana that are today the Amazon and Sahara. 这挑战了以前关于恐龙首先出现在更南端的信念。 This challenges the previous belief that dinosaurs first appeared further south. 该研究以计算机模型和化石为基础,在《当前生物学》中发表,表明恐龙可能在恶劣、干燥的环境中演变,后来由于消灭竞争对手的火山事件而多样化。 The study, published in Current Biology and based on computer models and fossils, indicates dinosaurs may have evolved in harsh, dry environments and later diversified due to volcanic events that wiped out competitors.
