Did early humans collect keepsakes 500,000 years ago?

from Phys.org

Most of us are familiar with the urge to pick up a seashell from the beach or keep a stone from a hiking trip. The object itself may be ordinary, but to the person who keeps it, it serves as a reminder of a particular moment, place or person. Where did this behavior come from? Did early humans do the same? A new study by Tel Aviv University researchers suggests that this practice stretches back approximately half a million years, with important consequences for the evolution of memory.

explained

A manuport is a natural object that has been deliberately taken from its original environment and relocated without further modification. Typically moved by human hand, some manuports are the result of other hominins. Common manuports include stones, seashells and fossils, which has led archaeologists and anthropologists to conclude they must have been chosen for their beauty. This recognition of an object’s aesthetic character suggests that certain manuports represent some of the earliest examples of art.

how it works

Archaeologists look for non-local stones, shells or fossils at sites where they have no use as tools or food. If an object was carried over distance and kept, that suggests it was valued for what it meant.

so what

Keepsakes imply a mind that can attach meaning to a memory and store it outside the head. If the habit is half a million years old, symbolic thinking and autobiographical memory may have deep roots in human evolution.
