Results from a model in which learners acquire their language from multiple teachers, and demonstrates that, in a more realistic model where learners have multiple cultural parents, populations of samplers can end up with stronger linguistic universals than in the single-parent model. However, strong innate constraints still do not evolve. $N=200,\hspace{0.17em}n=100,\hspace{0.17em}\mu =0.001,\hspace{0.17em}N=2,\hspace{0.17em}\mathit{ϵ}=0.05$, 1,000 generations.
