A study in Nature Communications found adaptations for low-light vision and hints at maintenance mechanisms that prevent retinal degeneration in extreme old age. However, despite the evolutionary and environmental distance, it may be possible to learn something about the preservation of vision in humans.

In an experiment with 421 participants who were required to recall words after a minute and a half and after a day, more than 4,000 “memory justifications” were collected. Despite a decrease in the number of items recalled, the linguistic content and detail of the justifications for the items that were correctly recalled remained the same.
