Researchers at the Max Planck Institute for Evolutionary Anthropology in
Leipzig, Germany have engineered a mouse whose FOXP2 gene has been swapped
out for a different (human) version. This is interesting because the gene
is implicated in human language, and this has changed how mice squeak. 'In
a region of the brain called the basal ganglia, known in people to be
involved in language, the humanized mice grew nerve cells that had a more
complex structure. Baby mice utter ultrasonic whistles when removed from
their mothers. The humanized baby mice, when isolated, made whistles that
had a slightly lower pitch, among other differences, Dr. Enard says. Dr.
Enard argues that putting significant human genes into mice is the only
feasible way of exploring the essential differences between people and
chimps, our closest living relatives.' The academic paper was published in
