Skeptics initially questioned the dating of the footprints due to concerns that aquatic plants like Ruppia cirrhosa used in the 2021 study could skew the results. However, a recent study in the journal Science introduced two new dating methods: radiocarbon dating of conifer pollen from terrestrial plants and optically stimulated luminescence for dating quartz grains in the fossil sediment. Both approaches provided consistent results, reinforcing the assertion of an early human presence in the Americas. This discovery is pivotal in the ongoing debate about when and how early humans first reached the Americas, offering insight into their remarkable journey. While many questions persist, these ancient footprints provide a fascinating glimpse into the challenges and opportunities faced by the first American inhabitants as they explored uncharted territories.
