EXCERPTS: In 2021, a groundbreaking study unearthed ancient footprints at White Sands National Park, New Mexico, sparking debates about their accuracy. According to previous theories, people first appeared in North America between 13,500 and 16,000 years ago.
An extensive follow-up investigation was carried out by a group of scientists, including co-author Jeff Pigati, a research geologist with the USGS, to validate these results.
[...] In the new study, radiocarbon dating was applied to conifer pollen found in the same layers as the seeds, offering another line of evidence. Kathleen Springer, a co-author and USGS research geologist, emphasized the importance of testing results using multiple methods. The USGS team remained confident in their original ages due to strong geological, hydrological, and stratigraphic evidence, but they recognized the need for independent chronological validation.
Isolating a substantial 75,000 pollen grains from the same layer, they determined that the pollen's age was statistically identical to that of the Ruppia cirrhosa seeds. Additionally, the researchers used optically stimulated luminescence to date quartz grains in the footprints, revealing a minimum age of approximately 21,500 years.
With three corroborating pieces of evidence, the USGS contends that the age range of 21,000 to 23,000 years is highly unlikely to be incorrect... (MORE - missing details)
