Do all the fibers obtained from animals give same smell on burning. Give reasons for your answer.

Yes, we can say that all the fibre obtained from animal give same smell on burning as we know burning silk gives the smell of burning hair and Wool is a protein fibre which we obtained from animal hair. Therefore, wool on burning gives a smell similar to that of burning of silk that is burnt hair.
