Final answer:
Molecular data has reshaped protist classification by revealing new genetic relationships among eukaryotes, resulting in the disassembly of Kingdom Protista.
Explanation:
Molecular data is the type of evidence most responsible for Protista losing its validity as a kingdom in modern classification systems. Through sequence analyses, new genetic relationships among eukaryotes have been revealed, leading to the disassembly of Kingdom Protista and the emergence of a classification scheme grouping all eukaryotes into supergroups based on evolutionary relationships.
