Der komplexe Walgesang

[Foss]

Ein toller Bericht mit Soundfiles, wie Wale mit einem Ton spielen und im Laufe der Jahre ein komplexes Lied daraus wird:

"Do you hear echoes?" she asked us. "From the bottom of the sea, the underside of the waves? [With] every sound, all the whales are listening. They have memorized this song."
All the males in a local group sing the song in roughly the same way. But over time, some parts of a group's song gradually change, too — in rhythm, pitch and duration — as the whales listen to each other, and together take up variations that eventually become a new tune.
