Evolution has come up in each of the last three papers, although the questions were not alike. Hardy-Weinberg’s theorem appeared among the short notes in 2024. A year later, FPSC asked about genetic drift, gene flow, and different forms of evolution. The 2026 question dealt with evidence for evolution from conventional and molecular biology. Other questions have been harder to anticipate. Algae for biofuel and phytoremediation appeared in 2024, followed by soil salinity and waterlogging in 2025. The 2026 paper included DNA replication and Mendel’s laws, topics that take the discussion back to basic genetics.
