- Organizing and summarizing search results for youPinus ponderosa originated around 150 million years ago during the mid-Mesozoic Era and radiated across Laurasia during the Cretaceous Period. Its evolution has been influenced by competition with angiosperms, leading to various adaptations, including superior drought resistance through deep root systems. Recent studies using mitochondrial DNA markers have clarified its evolutionary history and phylogeography, revealing how geographical and climatic processes shaped its modern structure. Additionally, Pinus ponderosa has adapted to fire-prone landscapes, showcasing diverse fire strategies. For more detailed information, you can refer to the Wikipedia page.5 Sources
