At more than 800,000 years old, the impressions, recently discovered in England, are the most ancient evidence of human life in northern Europe, and the earliest examples of human footprints outside of Africa.
Around 10,500 years ago, a hunter-gatherer walked through the mineral-rich sediment of the Chihuahuan Desert. The resulting footprints, locked in stone for millennia, have now been confirmed as the oldest human prints ever found in North America — shattering the previous record by 5,000 years.
If you're in a crowd, it doesn't take long to notice that people walk differently. A recent study suggests each person's gait is supposedly so distinctive that their way of walking could be used for identification purposes.
These rather adorable footprints - with a little chalk enhancement to make them more visible - were left by a group of small dinosaurs, revealing the ancient "road" they traveled all those millions of years ago.
HTC is updating the nav-focused Touch Cruise, which now features a new active-geotagging app called Footprints, which can easily stamp your location on notes, audio clips and photos.
