Almost certainly. Aboriginal people laugh . They are the closest thing we have today to cave men. And, as @gailcalled said all the jokes were new then.
Three cavemen finally get the wooly mammath to its knees after a long arduous battle. The caveman who was approaching the mammath from the rear quickly slips and his head gets jammed into the mammoth’s wooly butt.
It’s generally accepted that even dogs laugh. A dog laugh is like an excited, particularly noisy pant. It’s only used in play situations, basically when the dog is having a blast. Other dogs respond to the sound by relaxing. It seems to signal that there’s absolutely nothing to worry about.
I’m just offering this as confirmation that there isn’t a huge language or intelligence threshold requirement for laughter.
I did a study about this once. I used a prototype of the Orange Tree to send me back to the time of the caveman. I was very disappointed when I got there.
It seems someone had been there before me and had recruited all the cave men for Geico commercials!
@thesparrow I was thinking from the point of view of being unpolluted by modern influences. They are the closest approximate I could think of. Aside from the Belgians. LOL
