THEORY

 

 

 CO:49 Understand the general characteristics and classification of chordates and protochordates, focusing on key features and retrogressive metamorphosis in Urochordata.

CO:50 Explore the general characteristics and classification of cyclostomes, Chondrichthyes, and Osteichthyes, emphasizing classification up to order.

CO:51 Investigate the origin of Tetrapoda, general characteristics, and classification of Amphibia up to order. Also, examine characteristics and classification of Reptilia, including snake venom apparatus.

CO:52 Examine the general characteristics and classification of Aves up to order, and discuss the significance of Archaeopteryx as a transitional form. Additionally, explore feather development and flight adaptations.

CO:53 Study the general characteristics and classification of mammals up to order, focusing on Prototheria affinities and hair development.
