Hybridization
First and foremost, such a hypothesis discussion would not belong into the Sequoioideae but rather in the Genus:Sequoia article. Second, theres contradicting findings too and this kind of discussion can't be biased. And third, there's no Sequoiadendron fossil older than about 60ma; while the fossil record of genus Sequoia is much older. It's highly unlikely they needed Sequoiadendron to come up with modern Sequoia sempervirens. Their respecitvie ecological spectrum was different so they rarely occurred together; and if any such hybridization happened, then most probably way before Sequoiadendron even existed. So please consider removing it, at least here. --Rosetta — Preceding unsigned comment added by 77.181.80.252 (talk) 20:12, 2016 February 20 (UTC)
