HII galaxies are dwarf starbursts at low redshift with high star formation rates and low metallicities. These are physical properties expected of the young galaxy population in the early universe. In particular, HII galaxies present a scaling relation between L-sigma analogous to the Faber-Jackson relation for ellipticals and the Tully-Fisher relation for spirals. In this talk or poster, I will discuss the origin of the supersonic motions from feedback to gravity producing the observed sigma, the effects of galactic evolution on the scaling relation, and finally the validity of the application of this powerful relation to the high redshift universe.
