The following passage traces the scientific reevaluation of Neanderthal cognitive capabilities.

For over a century after their initial discovery in the Neander Valley in 1856, Neanderthals were depicted in both popular culture and scientific literature as cognitive failures—brutish, stooped creatures incapable of abstract thought, symbolic communication, or complex planning. This view was reinforced by early anatomical reconstructions of Neanderthal skeletal remains, which mistakenly emphasized arthritic deformities as typical species-wide traits rather than individual pathologies. However, in the late twentieth century, this long-standing paradigm began to shift as new archaeological discoveries challenged the assumption of cognitive inferiority.

First, archeologists uncovered compelling evidence of intentional burials, most notably at the Shanidar Cave site in Iraq, where pollen analysis initially suggested that colorful flowers had been deliberately placed on Neanderthal graves. While the specific 'flower burial' interpretation was later debated by skeptics who attributed the pollen to burrowing rodents, the physical discovery of systematically buried, intact skeletons remained undisputed, pointing to structured social behavior and a potential awareness of mortality.

The argument for Neanderthal cognitive sophistication deepened with the discovery of non-utilitarian, symbolic artifacts. In various European cave sites, researchers found pierced animal teeth and marine shells stained with red ochre pigment, dating to long before modern Homo sapiens arrived in those regions. These items served no practical utility for hunting or shelter, indicating that Neanderthals engaged in symbolic and decorative practices. Critics initially argued these items were either scavenged from early modern humans or represented stratigraphic mixing of soil layers, but subsequent high-resolution radiocarbon dating confirmed their Neanderthal origin.

The final pillar of the modern consensus emerged from paleogenetics. In 2010, the successful sequencing of the Neanderthal genome revealed that they shared the FOXP2 gene—associated with speech and language development in Homo sapiens—and that they interbred with early modern humans. This genetic evidence suggests that communication between the two species was complex enough to facilitate social integration, effectively dismantling the primitive narrative and leaving researchers to debate not whether Neanderthals possessed symbolic thought, but how closely their minds mirrored our own.

Based on the passage, in what order does the author introduce the evidence and arguments to trace the transition from viewing Neanderthals as primitive to recognizing their cognitive sophistication?
