The FOXP2 gene first gained prominence after researchers identified a mutation of the gene in three generations of a family from England who all had difficulties speaking, understanding complex sentence structures, and moving muscles to articulate sounds. Since this discovery, researchers have found that the same FOXP2 gene has existed in a more or less stable state in all mammals with the exception of humans, where two significant changes in its coding have occurred. The change, which may have occurred as recently as a hundred thousand years ago, suggests that the evolution of the FOXP2 gene may have contributed to human language development. The mouse study seems to add credence to this hypothesis.
Does the fact that mutation and natural selection may explain the emergence of human language question the need of a God to explain our existence then? Not at all, Dr. Collins says in The Language of God:
“Freeing God from the burden of special acts of creation does not remove Him as the source of the things that make humanity special, and of the universe itself. It merely shows us something of how He operates.”
