The gist
- Earlier research dated human footprints at White Sands, New Mexico, to about 23,000 years ago.
- Conifer forests gave way to oak and sagebrush, and the lake became saltier.
- People kept visiting and living in the area as it changed.
What happened
A study in Science Advances, co-authored by Bournemouth University researchers, reconstructs the environment around the White Sands footprints. As temperatures rose, conifer forests gave way to oak trees and sagebrush, the lake became saltier and plants suited to dry conditions increased.
Why it matters
The study gives environmental change a human timescale, showing that people could experience substantial changes to familiar surroundings within their own lifetimes.
How we know
Bournemouth University's account of the study describes researchers reconstructing environmental changes from ancient pollen and organic molecules preserved in sediment samples.
What we don’t know yet
The footprints preserve moments, with gaps between them. They don't show exactly how people moved or behaved; as one researcher put it, they are individual frames, not a continuous movie.

NASA analysis confirms Artemis II heat shield performed as expected
NASA's post-flight assessment finds substantially fewer spots of lost charred material after Artemis II than after Artemis I.
