The biggest myths about Neanderthals - Bruce Hardy

In 1856, fossils discovered in Germany’s Neander Valley initiated the scientific understanding of Homo neanderthalensis, commonly known as Neanderthals – an extinct human species. This discovery coincided with a growing acceptance of geological timelines and evolutionary theory, challenging the previously held belief in a 6,000-year-old Earth. Initial interpretations, however, were heavily biased, portraying Neanderthals as intellectually inferior “oafs” destined for extinction due to their supposed inferiority to Homo sapiens. These early depictions, often inaccurate based on skeletal evidence, showed them as stooped, hairy, and possessing ape-like features.

Neanderthal Characteristics & Lifestyle

Over a century of archaeological work, uncovering remains from over 300 individuals, has drastically revised this understanding. Neanderthals differed physically from modern humans, exhibiting larger, deeper-set eyes, shorter, more muscular builds, and larger hearts and brains, resulting in higher caloric needs. They inhabited Europe and Western Asia for over 350,000 years, and for at least 10,000 years, coexisted with Homo sapiens. Evidence suggests a complex lifestyle far beyond basic survival.

A Neanderthal skeleton found in Iraq displayed severe injuries – a severed arm, injured leg, and probable blindness and deafness – yet survived with ongoing support from his community, indicating advanced social care. Similarly, a French skeleton revealed an elderly individual with significant dental loss and mobility issues, suggesting assistance with food preparation. Both sites demonstrated intentional burial practices, implying concern for the ailing and deceased. Dental analysis further suggests medicinal use of plants with anti-inflammatory and antibiotic properties.

Technological & Symbolic Capabilities

Early assumptions of Neanderthal hunting strategies focused on brute force attacks on large game. However, evidence of cut marks on rabbit bones, and traces of scales and feathers on tools, demonstrate skill in capturing small game, potentially using snares and projectiles. They were adept toolmakers, crafting implements from various materials, utilizing birch bark glue, fire-hardened digging sticks, and sophisticated 3-ply string made from bark fibers.

Furthermore, discoveries challenge the notion that symbolic thought was exclusive to Homo sapiens. Neanderthals selectively collected bird feathers, painted and perforated shells, and wrapped eagle talons, potentially for adornment. Markings on an elk toe bone and three cave paintings in Spain (dated to approximately 65,000 years ago, though this dating is still under review) suggest artistic expression. Mysterious structures created from broken stalagmites in a French cave hint at possible spiritual or ceremonial practices.

Interbreeding & Extinction

The sequencing of the Neanderthal genome in 2010 revealed interbreeding between Homo sapiens and Neanderthals. Modern humans of non-African descent carry between 1-4% Neanderthal DNA, resulting from numerous interbreeding events.

The cause of Neanderthal extinction remains debated. Theories include cannibalism, disease, climate change, and competition with Homo sapiens. A prevailing hypothesis suggests gradual absorption into Homo sapiens populations due to interbreeding, as Neanderthals lived in smaller groups.

Evolutionary Perspective

The current consensus is shifting away from a linear, tree-like model of human evolution towards a “braided stream” model, acknowledging periods of separation and reconnection between different hominin groups. As stated implicitly throughout the findings, “each discovery raises questions about just how much we share” with our evolutionary cousins.

Key Concepts:

• Homo neanderthalensis: The extinct human species known as Neanderthals.
• Hominin: A member of the human lineage after the split from chimpanzees.
• Genome: The complete set of genetic instructions of an organism.
• Interbreeding: The mating of individuals from different species or populations.
• Braided Stream Model: A model of human evolution that depicts a network of interconnected lineages rather than a linear progression.
• Skeletal Findings: Evidence derived from the study of bones.
