Reply #147: i agree w. yr main point but to pick a tiny nit [View All]

[pitohui]

dinosaurs, avian ancestors (also dinosaurs), reptiles, and mammals had a common ancestor

according to smithsonian museum of natural history, true dinosaurs and true mammals both appeared at the end of the triassic and lived through the entire mesozoic together, you may check my facts here:

mammals never recovered, they just never amounted to a hill of beans to begin w. until the dinosaurs kicked & got out of the way

but yr point is well taken & one that concerns me also, no large animals, be it reptile, bird, or mammal will survive a low oxygen, high methane atmosphere

humanity may survive but imagine the misery of life lived in domes & spacesuits

there can be no freedom where the very air is poison & all live in tin cans
