DOLPHIN MOMS DO BABY TALK WITH THEIR CALVES

DOLPHIN MOMS DO ‘BABY TALK’ WITH THEIR CALVES

Baby talk or Motherese/ Parentese is a speech pattern nearly universal across cultures and languages in human caregivers interacting with children. It is characterized by a higher than usual pitch, exaggerated intonation, repetition, calling attention to objects and use of slow stretchy speeches. What we know about baby talking in other nonhuman species is sparse. Now, researchers have  found evidence for baby talk in bottlenose dolphin, a species that shows parallels to humans in their long-term mother–offspring bonds and lifelong vocal learning. 

Researchers analyzed audios from made wild bottlenose dolphins in waters near Sarasota Bay, Florida, United States, and found that females produced signature whistles with significantly higher maximum frequencies and wider frequency ranges when they were recorded with their own dependent calves.

This finding provide an example of convergent evolution of motherese in nonhuman mammals, and may help us understand how motherese can facilitate vocal learning and bonding in nonhumans as well as humans.

What to boycott NOW to help stop Israel’s unfolding genocide of Palestinians in Gaza

What to boycott NOW to help stop Israel’s unfolding genocide of Palestinians in Gaza

We call on our supporters to strengthen our targeted boycott and divestment campaigns to maximize our impact!

Reminder that boycotting DOES work, there is historic proof! Don't let anyone discourage you otherwise!

The BDS movement uses the historically successful method of targeted boycotts inspired by the South African anti-apartheid movement, the US Civil Rights movement, the Indian anti-colonial struggle, among others worldwide.

We must strategically focus on a relatively smaller number of carefully selected companies and products for maximum impact. Companies that play a clear and direct role in Israel’s crimes and where there is real potential for winning, as was the case with, among others, G4S, Veolia, Orange, Ben & Jerry’s and Pillsbury. Compelling such huge, complicit companies, through strategic and context-sensitive boycott and divestment campaigns, to end their complicity in Israeli apartheid and war crimes against Palestinians sends a very powerful message to hundreds of other complicit companies that “your time will come, so get out before it’s too late!”
