Vedclass · Answer

(C) Statement $C$ is incorrect. According to the geological time scale,invertebrates were formed and active approximately $500$ million years ago,but the statement implies a specific evolutionary event that is often cited as $500$ million years ago for the origin of invertebrates,whereas the fossil record suggests they appeared earlier (around $540$ million years ago during the Cambrian explosion). However,in the context of standard biology textbooks,the statement regarding $500$ million years ago is often considered inaccurate or misleading compared to the established timeline of the Cambrian period. Statements $A$,$B$,and $D$ are scientifically accurate descriptions of evolutionary processes and biological adaptations.
