It's job frenzy out there. You can see here seven postdoctoral positions in the Dutch research consortium "Language in Interaction" including one on language evolution below:
WP 5: Language evolution and diversity
The goal of this WP is to contribute to a better understanding of the biological underpinnings of linguistic universality as well as diversity, both at the population level (between languages and between species) and at the individual level (within a language). We are looking for a postdoctoral researcher in this area. The preferred area of specialization is evolutionary modelling of language with respect to diversity in communication. Other possible areas of expertise may include language diversity, individual differences in language abilities, animal communication, and genetic influences on speech and language.
