FLIPPER BEWARE!
When I was growing up I enjoyed watching reruns of the television series Flipper. As a little kid, I was quite fond of this unusually intelligent dolphin. According to new research, Neanderthals were fond of dolphins as well.* But instead of delighting in watching them perform, these hominids liked to eat them.
Neanderthals appear in the fossil record between 250,000 and 150,000 years ago and go extinct about 30,000 years ago. They lived in western Asia, Europe, and the Middle East. Popular views about human origins position Neanderthals as immediate predecessors to modern humans. Other more sophisticated treatments of human evolution, like multiregionalism, argue that these hominids gave rise only to European people groups.
Because of their potentially prominent role in human evolution, anthropologists are interested in Neanderthal biology and behavior. This interest motivated an international team of paleoanthropologists and archeologists to analyze the fossil and archeological remains from two coastal caves located in Gibraltar. These caves held several kinds of artifacts that included Neanderthal-made products located at specific levels and layers within the cave, and also artifacts attributed to modern humans found at different sites within the cave. Associated with these finds were fossilized animal bones interpreted as the food stuff leftover from hunting and gathering expeditions.
Cataloging the species that comprise the animal remains provided researchers some insight into the behavior of Neanderthals and some of the first modern humans. For both the Neanderthal and the modern human locales, researchers documented mollusk shells and the remains of red deer, ibex, wild boar, bear, birds, tortoises, and fish, as well as dolphins and seals. Additionally, the scientists discovered rhinoceros remains associated with the artifacts left behind by modern humans.
The researchers interpreted these results as evidence that Neanderthals and modern humans had similar hunting and gathering practices, and, therefore, had identical cognitive capabilities. They were particularly impressed with the ability of Neanderthals to make use of dolphins and seals as a food source. They argue that to effectively do so means that Neanderthals had some sense of the seasonal activities of these animals. Dolphins are known to beach themselves at certain times of the year. It appears as if Neanderthals and modern humans took advantage of beached animals. Seals come ashore during mating season. Presumably, Neanderthals and modern humans clubbed these animals to death during mating season. Interestingly, only juvenile seal remains were recovered from the Neanderthal sites, indicating that they likely went after easier targets.
Based on this new insight, some anthropologists conclude that Neanderthals had skills that compared to modern humans alive at that time, since they seemed to have exploited the same range of resources as modern humans, and likely used similar tactics to hunt and gather. If so, does this mean that Neanderthals are no different than modern humans? What does this discovery mean for the RTB model of human origins?
