Vedclass · Answer

(B) According to the theory of chemical evolution,life originated from non-living organic molecules.$1$. First,simple organic molecules formed,which then polymerized to form macromolecules (like proteins,nucleic acids,etc.).$2$. These macromolecules aggregated to form non-cellular aggregates (like coacervates or protobionts).$3$. These aggregates eventually gave rise to the first primitive unicellular organisms.$4$. Over millions of years,unicellular organisms evolved into complex multicellular organisms.Therefore,the correct evolutionary sequence is: Macromolecules $\rightarrow$ Non-cellular aggregates $\rightarrow$ Unicellular organisms $\rightarrow$ Multicellular organisms.
