The first neanderthal individual revealed to science, now known as Neanderthal 1, was discovered in 1856 in Germany's Neander Valley (in German, the name Neanderthal means "Neander Valley"1). The bones were embedded in clay that quarry workers were removing from a cave.
Originally, before quarrying began, the "valley" was really a narrow gorge of limestone cliffs pierced by the rushing waters of the river Düssel.2 But extensive stone removal has since obliterated the cliffs, as wel as the cave where the first find was made.
The workers thought they had found the bones of a cave bear (Fuhlrott 1859), and turned their find over to a local naturalist, Johann Carl Fuhlrott. He soon realized they were the remains of an ancient human being. Fuhlrott took the material to anatomist Hermann Schaaffhausen in Bonn for confirmation of his opinion and the two jointly announced their discovery in 1857 (Fuhlrott 1857, Schaafhausen 1857).
Much of the original specimen was lost because the quarry workers failed to recognize the importance of what they had found. Fuhlrott himself did not inspect the site until two weeks later. By then, the remaining bones were buried deep in a great heap of clay. As a result, the only portions of the skeleton recovered were the skullcap, two femurs, several arm bones, part of the left ilium, fragments of a scapula, and some ribs (Schaafhausen 1888). Surprisingly, however, additional material from Neanderthal 1 has recently been located (see Note 3 below).
If Fuhlrott and Schaaffhausen thought the facts indicated that their specimen differed in any essential way from modern humans, they did not say so initially. The idea that the bones were those of a distinct type of human, previously unknown, was first proposed by English geologist William King, the first scientist to use the name Homo neanderthalensis (King 1864).
Due to the careless mode of its recovery and to the subsequent destruction of the site, the age of Neanderthal 1 was long unknown. However, C14 dating has shown it to be about 40,000 years old (Schmitz et al. 2002).
Over the years, many additional specimens of Homo neanderthalensis have come to light — the total now stands at about 400 separate individuals. Consequently, the bony anatomy of this hominid is well known. In Homo neanderthalensis, brain size was on average 11 percent larger than our own — the mean cranial capacity of an adult was 1500 cc, versus 1350 cc for modern humans (Ponce de León et al. 2008: 13767).
Notes:
1. In 1901 a spelling reform in Germany replaced th with t through out the language. Thus, words such as Thal and Thier became Tal and Tier. However, scientific names are unaffected by such changes; so Homo neanderthalensis retained its th. Some scientists have tried to change the English name of this hominid from Neanderthal to Neandertal, to bring it in line with modern German spelling, but this initiative seems to be losing steam due to the inertia of the long-established English spelling Neanderthal.
2. The Neander Valley is not named for the river, the Düssel, that runs through it. Rather it gained its epithet from the 17th century pastor and hymnist Joachim Neumann, whose last name was rendered in Greek as Neander. Neumann frequented the area and found inspiration for his hymns in the then rushing waters of the now obliterated gorge.
3. Remarkably, Ralf Schmitz and Jurgen Thissen, of Germany's Office for the Preservation of Archaeological Monuments, have recently managed to relocate the site where the other pieces of the original Neanderthal skeleton were dumped. In old paintings and maps of the cave, they were able to recognize a rock that still stands at the site. "They dug a couple of deep trenches nearby and began to sift through the rocks and debris at the bottom," says one of their colleagues, Barbel Auffermann, of the Neanderthal Museum. "Eventually, they found some bat teeth and pieces of stalactites. You only get those in caves." Then they set to work in earnest sorting through tons of earth. Eventually they found 20 additional pieces of bone. One actually fit the left knee joint of the original Neanderthal individual!
