That study was about the presence of a neural template (and perhaps a linguistic one). Before the study people thought it might be possible for any singing bird to sing any other bird's songs. An abstracted view of the point of the study is perhaps there is some hardwiring in our communication. Kernels of hardwiring that can't be nurtured away. In humans it would be analogous to the universal laws of linguistics. It was just something to think about. Next time I'll just link the study.
