Dear student,

As interesting as Zoology and History sounds, there isn't a course that could offer you both subjects together as zoology is a science based subject and history is included humanities.

But keeping your interest into consideration, I would suggest you to go for Anthropology, the study of human evolution, so you see, you can get a combination of both!

Another suggestion would be to take up zoology and simultaneously prepare for UPSC, if that is your calling, but mind you, that will require you to show your expertise in many more subjects.

The rest of course, is your call. Hope it help.

Good luck.

Cheers!
