Lemurs Intentionally Sing Off Key
Lemurs Intentionally Sing Off Key
Singing out of tune can get you noticed, indris lemurs have discovered. Birds, humans and certain other animals strive to hit the right notes, but for young indris lemurs, the goal is to get noticed by singing out of sync and out of tune, new research finds.
The indri, also known as the babakoto, is one of the few primates that sing. This endangered species from Madagascar lives in small groups in the eastern rainforests of the island nation. Both males and females sing in their families that consist of a dominant female and male, their immature offspring, and one or more low-ranking young adults. Their songs appear to play an important role in territorial defense and group formation.
Young, lower-ranking indris, however, prefer to sing in antiphony rather than staying in sync with the rest of the lemur chorus, the scientists discovered. These youngsters alternate their notes with those sung by the dominant pair. The researchers propose that this is a tactic that lets the eager semi-outsider maximize his or her solitary singing and emphasize an individual contribution to the song.
How about you? Do you like to stand out from the crowd? You can lead the way to more ethical and compassionate dining amongst your family and friends by choosing a more plant-based diet.
