jrf> ウィルスがそのような「意図」はもってなかったとしても、動物はそう「意図」して弱毒なウィルスを選ぶよう、症状がヒドイほど表に出ない・陰で死ぬ選択はできる。 《ゆきんこ:X:2024-06-10》 https://x.com/Be_Yukino_55/status/1799904508597661743 >日本でも未だ根強い 「ウイルスは、宿主を絶滅させぬよう弱毒化する」 という主張を T.Ryan Gregory 博士が、 ・進化生物学的な根拠はまったくない ・進化の仕組みに関する誤解だ とバッサリ否定。 "Evolution does not work that way" (進化って、そうはいかないよ) < 《T. Ryan Gregory:X:2024-06-09》 https://x.com/TRyanGregory/status/1799475589969244186 > Students sometimes ask me if dinosaurs would have inevitably evolved to be like humans if given more time. Well, dinosaurs were a very diverse group that lasted for 165 million years and it didn't happen. We see the same misconception about viruses. People often assume that viruses will inevitably evolve to become seasonal or benign, usually because of some argument about not driving their hosts extinct. There is simply no basis for this in evolutionary biology. It's a misconception about how evolution works. No inevitable dinosauroids given enough time. No guaranteed mild, seasonal SARS-CoV-2 given enough time. EVOLUTION DOES NOT WORK THAT WAY <
