HEY DEAR .......!!!!
During the course of evolution the need for well separated and more efficient circulatory system was felt due to energy expenditure..
So the crocodiles and other species of their order CROCODILIANS (alligator and gharial/ Gavialis) developed a four chamfered heart with 2 auricles and 2 ventricles so that the pure and the impure blood is kept separated throughout the body and the heart. ..
Birds and mammals also have a four chambered heart which proves that birds and all mammals evolved from reptiles. .

Crocodiles have four chambered heart so that oxygenated and deoxygenated blood do not get mixed.
