On the upside, oxygenation led to the explosive diversity of complex, high-energy organisms that led to us[0]! Without living on the edge, you don't get complex, powerful organisms (like mighty trilobites). Plus, there's no telling how much reprogramming for stronger oxidization-repair mechanisms can provide. Mammalian mitochondria are inferior to bird mitochondria (and birds have them in their blood cells unlike us which may help[1]), allowing birds to live longer even with higher metabolisms than mammals. Evolution hasn't exhausted the possible. There's hope! Just not for us. :) Which is fine; everything's fine. 0: https://en.wikipedia.org/wiki/Cambrian_explosion#Increase_in... 1: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3686644/ |
