This week I’m talking about our understanding of how humans differ genetically in order to have acquired speech, and how that understanding has changed based on current research.

Here are the links to the articles I discuss:

1. A forkhead-domain gene is mutated in a severe speech and language disorder

2. Molecular evolution of FOXP2, a gene involved in speech and language

3. The Derived FOXP2 Variant of Modern Humans Was Shared with Neandertals

4. No Evidence for Recent Selection at FOXP2 among Diverse Human Populations
