How has the concept of "found objects" challenged traditional definitions of art?

Since Marcel Duchamp's infamous "Fountain" introduced the idea of a ready-made in the early 20th century, the use of found objects has provoked ongoing debates in the art world. These items, which are often ordinary, everyday objects or materials repurposed into art, have pushed the boundaries of what can be considered art by challenging notions of originality, authorship, and creativity. This approach has been further explored by artists like Robert Rauschenberg and Michael Craig-Martin, raising the question of whether the artistic intent and context can elevate an otherwise mundane object to the status of an artwork. How does the incorporation of found objects continue to influence contemporary art and public perception of what constitutes art?
