The ascent of man

According to Anthropology, Paleontology, Biology, Morphology, and anatomic and genetic data, [which accounts for tens of thousands of scientists, not just a holy 99] and due to what is known of similar anatomical and physiological known systems, the timeline of human evolution begins with the advent of mammals giving live-birth to offspring 160M years ago, placental mammals 125M years ago, and primates 100M ago. Homo sapiens 0.8M years ago.

From the point of placenta mammals forward, organ physiology and subsequent adaptability are virtually identical to us, meaning those ancestors were able to deal with widely variable climate changes without extinction.

With human intellect, our adaptability increases; it does not shrink. Political science did not teach the Green New Deal these facts,. nor, apparently, the rest of you climate change fanatics. And you're worried about a 2 degree C rise in global temperature? Really? Did we defrock St. Darwin and his adaptability psalm?

You want to be extinct, be my guest. The line forms over there on the left. Where else?

800,000 years ago, about when humans made their debut bow on stage Earth, and when we obviously began the plot to destroy it, other mammals, with whom we happen to share virtually identical respiratory systems, [not to mention others] were already in full form, and had been since the dinosaurs took their final bow 65M years ago. Since that time, the Earth has seen higher concentrations of both CO2 and CH4 [methane], and both were being exhausted into the atmosphere as a natural consequence of life on earth, including farting cows [rice paddies do too, by the way]. And, more adaptable to the conditions than we were with one another; that condition exists today. Humans are an adaptable species. But, suddenly, because 99 climatologists in lockstep have convinced an entire cast and crew of flaming progs that the Earth is doomed because it appears, once again, CO2 and CH4 are rising above "historic" levels [less than 200 years that we can measure accurately], we must have lost that adaptability. What's lost is the resistance to breathe bozone, and that has far more consequences of damage than CO2 or CH4.
