The human tracks of White Sands National Park record more than 1.5 km (0.93 mi) of one-and-return trips. They show the footprints of a female or juvenile male who joins the footprints of a toddler.
"A teen or younger adult woman separating the two trips by at least several hours takes a young child in at least one direction," noted lead author Dr of Bournemouth University and colleagues. Said Sally Reynold.The team found tracks in the dried up lakefront, with other footprints dating from 11,550 to 13,000 years ago. Due to the drying of the sludge surface in the east of the lakebed, footprints remained for thousands of years.
Cornell University researcher Drs. Thomas Urban said, "When I first saw the intermittent footprints, a familiar scene came out. "This research is important in helping us understand our human ancestors, how they lived, what their similarities and differences are, "Dr. Reynold said.
"We can put ourselves in this person's shoes, or footprints, and imagine what it was like to carry a child from hand to hand as we walk through a difficult area surrounded by potentially dangerous animals. " Scientists found earlier footprints at mammoths, giant sloths at the site, saber-toothed cats and tough wolves.
“Massive landslides and Colombian mammoths were merged after forming the human track, which suggests that the area hosted both humans and large animals at the same time, alarming the journey taken by this person and child Made, ”said. The team's paper was published in the Quaternary Science Review-Journal.
