When was the first H. neanderthalensis specimen discovered?

The first specimen of Homo neanderthalensis was discovered in 1856 in the Neander Valley near Düsseldorf, Germany. This groundbreaking find marked a significant moment in the field of paleoanthropology, as it was the first fossil identified as belonging to a species distinct from modern humans. The discovery led to considerable interest and research into early human ancestors and the evolution of hominins. The Neanderthal remains included a skullcap and various bones, which ultimately contributed to the recognition of Neanderthals as a separate species that lived alongside early modern humans. The year 1856 thus stands as a pivotal reference point in the study of human evolution.
