Gary Larson cartoon strips always have cavemen named Thak or Og. It got me to wondering- did cavemen have names? When did people start using names?
It’s time for Question of the Week and this week Lucka has been looking back in time with this question…
Kat: - Hey, scientists. This is Kat from Kansas City, Missouri. I was reading a Gary Larson comics the other day and noticed all the cavemen had silly names, and it got me wondering, did cavemen even have names? When did human beings start naming themselves?
Lucka - We asked you what you thought on Facebook. Alejandro wrote…
Alejandro - Did you suppose the first name was an insult?
Lucka - And Andrew thinks…
Andrew - I think early humans were given name to their young out of affection rather than necessarily like we do today.
Lucka - To get to the bottom of this caveman mystery, I listed the help of linguist Professor Shigaru Miyagawa from MIT. But first what do we mean by cavemen?
Shigaru - The thing to keep in mind is that the idea of cavemen is for the most part fiction that was created by popular culture. It’s based on things that appear to be real. A lot of things have discovered in caves like paintings and artefacts with symbols. But the image of them hunting alongside dinosaurs for example is a romantic fiction of evolution.
Lucka - Got you. So, let’s step away from the caveman like Fred Flintstone and look instead at our own species, homo sapiens. How did we first start to communicate with each other?
Shigaru - I think a lot of theories actually you could imagine. One theory says that communicated in single words just like monkeys. Some monkeys have a single word system like snake, leopard, and eagle to let the others know that a prey like a leopard is nearby. Another theory which is by Charles Darwin says that pre-humans communicated by singing just like birds. He observed that bird song is the nearest origin to human language. And birds sing to attract mate. So maybe our ancestors communicated this desire to mate by singing. Which of these is true, single word system or singing? Well, we don’t really know because language doesn’t fossilise. Actually, what I think is that both were probably true. Our ancestors communicated in words to warn others of a prey in the vicinity and singing to attract mate.
Lucka - This singing could have been an early framework for things like grammar and the early start of language. But back to the original question, when did names come along?
Shigaru - Human language appeared only recently. Some say about 100,000 years ago. That was around the time the homo sapiens were migrating out of east Africa into the Eurasian continent. They were hunter-gatherers. Once farming became possible around 10,000, maybe 12,000 years ago, you had more fixed rules in a larger community of people. So, you had to come up with a way to distinguish individuals. That’s when you started to assign names. Certainly, the origin of human language in evolution is one of the great mysteries of science.
Lucka - The best we can do without a time machine. Thanks, Shigaro. Next week, we will be scanning the horizon to answer Loot’s question.
Loot - How did the moon get its markings?
Some animal species have unique callsigns which are used by other members of their species to get their attention. Parrots spring to mind. evan_au, Thu, 9th Jun 2016
A very long time ago. Before writing I'm guessing. Maybe before Homo classification which starts ~2 million years ago. Vocalization would have to have evolved enough to produce many different sounds. So looking at the vocal cords, I think I recall the hyoid bone can give some evidence of when vocal cords became sophisticated enough for name calling. Might be something in the fossil record with that, assuming that bone is recoverable after millions of years. Villi, Thu, 16th Jun 2016
There are two sides of the brain. The left side differentiates data, while the right side of the brain integrates the same data. Like in math differentiation finds the slope of a curve at a given point; specific. While integration finds the area under the curve; generality. Feelings tend to be right brain since a feeling like sad to happy can be induced with endless scenarios. Logic is more left brain since it build from specific premises.
