Vedclass · Answer

(A) The evolution of the heart shows a transition from simpler to more complex structures:$1$. Shark (Fish): Possesses a $2$-chambered heart (one atrium and one ventricle).$2$. Salamander (Amphibian): Possesses a $3$-chambered heart (two atria and one ventricle).$3$. Chameleon (Reptile): Possesses an incompletely $4$-chambered heart (two atria and a partially divided ventricle).$4$. Crocodile (Reptile): Possesses a $4$-chambered heart (two atria and two ventricles),which is more advanced than other reptiles.Therefore,the correct evolutionary sequence is Shark $\rightarrow$ Salamander $\rightarrow$ Chameleon $\rightarrow$ Crocodile.
