found in New Mexico, challenging once-conventional wisdom regarding humans migrating to the New World from Russia roughly 15,000 years ago, new research confirms.
After the results of the 2021 study were revealed, questions concerned whether the seeds of aquatic plants used for the original dating may have absorbed ancient carbon from the lake — which could have thrown off radiocarbon dating by thousands of years. The new study isolated about 75,000 grains of pure pollen from the same sedimentary layer that contained the footprints.

Previously, archaeologists thought human ancestors arrived about 15,000 years ago. The research was published Thursday in the journal Science. Scientists analyzed conifer pollen and quartz grains found at the site to reach date estimates. Earlier research that analyzed seeds of aquatic plants found at the site also produced similar date estimates. Ancient humans at White Sands lived alongside giant ground sloths, bison and other megafauna.
