Close波特啦
唔知
病毒1899年先發現到 姐係132年前
細胞講緊係X,000,000年前（仲向前考證緊）
細胞冇左病毒仍然可以複製
病毒冇左細胞就複製唔到
人腦都記唔住咁多野 點解細胞入面既DNA同病毒入面既RNA可以咁準確客觀咁紀錄晒遺傳信息？

路不轉，名轉
理論上
病毒都要依賴細胞先replicate 到
或者病毒本身都係由生物製造/退化出黎 (FF)
應該都係先有生物後有病毒
調轉諗 如果先有病毒
佢既唔會進化成生物 又唔能夠單獨生存
唔太合理

個句我都補左句 FF
你問一問就走左去google
當然virus origin 都係流於理論階段
Random google 左篇有用quote 既文
一般virus origin 有3個hypotheses
1. The progressive, or escape, hypothesis states that viruses arose from genetic elements that gained the ability to move between cells;
2. the regressive, or reduction, hypothesis asserts that viruses are remnants of cellular organisms; and
3. the virus-first hypothesis states that viruses predate or coevolved with their current cellular hosts.
頭兩個就係我想講既virus 係生物甩出黎既野eg transposon 個d 而頭兩點都係支持先生物後病毒
而第三點比較有趣 佢postulated 世界本身係有d 識self replicate 既病毒(如有 佢應該係RNA virus 因為 RNA 先可能有enzymatic effect）
佢地慢慢進化成有cell membrane 既生物
咁到有左host之後佢地就變到唔識replicate
