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 Ecology and evolution of pine life histories | Annals of Forest …
Pinaceae dates to the early Mesozoic and the genus Pinus perhaps mid-Jurassic (Axelrod 1986; Millar 1998). The earliest fossil record of Pinus is Early Cretaceous, 130 Ma (Millar 1998), and molecular phylogenetic estimates provide a wide range of estimates between 102 and 190 Ma (Willyard et al. 2007).
