Scientific paper

We present a review on the determination of the primordial helium abundance,
Yp, based on the study of hydrogen and helium recombination lines in
extragalactic H II regions. We also discuss the observational determinations of
the increase of helium to the increase of oxygen by mass Delta Y/Delta O, and
compare them with predictions based on models of galactic chemical evolution.
