Last month, I posted about laughing rats. Well, here’s the follow-up: chortling chimps, orangutans, gorillas, and bonobos. From the article posted on Science News’s website:
Don’t try this at home, but tickling a gorilla, orangutan, bonobo or chimp can inspire bursts of grunting sounds.
Yes, that’s laughter, says Marina Davila Ross of the University of Portsmouth in England. She and her colleagues analyzed sounds of ticklish great apes as well as human babies and traced a shared family tree of laugh sounds. Laughter’s roots go back at least 10 to 16 million years, Davila Ross and her colleagues suggest online June 4 in Current Biology.
Here’s a link to the study.
The National Zoo's newest baby
My source at the National Zoo (otherwise known as my husband) sent me this photo of the newest bundle of gorilla joy. Apparently mom gave birth in the exhibit in full view of the public on Saturday. They don’t know if it’s a boy or a girl, and zoo folks may not get a good look to find out for a while. Read more in the Washington Post story.
