To return to a former or less developed state.

Often used in psychology to describe a person returning to childlike behaviors under stress, or in statistics for 'regression toward the mean.'

The story behind the word. From the Latin 'regressus,' the past participle of 'regredi' (to go back). It is the direct opposite of 'progress.' In the 19th century, it became a key term in evolutionary biology to describe species that seemed to lose complex traits.
