1952 Glottochronology and its unreliable clock contested 0 cit. Morris Swadesh proposed that core vocabulary is lost at a steady rate, so the share of words two languages still share could date when they split. Applied to African languages, the method promised firm ages for migrations. Later linguists showed the rate is not constant and that borrowing distorts the count. The dates it produces are now treated as unreliable and are marked contested. science ●●

1952 Structural amnesia in the genealogy 0 cit. Laura Bohannan, working among the Tiv of Nigeria, showed that genealogies are reshaped to fit present-day relationships. Names that no longer matter for land or rank quietly vanish, so a family tree stays a charter for who belongs rather than a fixed record of descent. This is why a king-list or lineage cannot be read at face value as a count of real generations. science / society ●●

Anthony Allison, working with East African populations, showed that people carrying one copy of the sickle-cell gene were better protected against deadly malaria. The trait is common in lowland farming and fishing communities where malaria is intense and rarer in the highlands where it is not. This is balancing selection: the gene persists because carriers survive malaria even though two copies cause disease. The pattern follows the mosquito, not any ethnic line. science ●●●

1956 Hubbert predicts peak oil 0 cit. Geologist M. King Hubbert argues that US oil output would peak around 1970 and then decline, a curve later applied to world production.

1962 Lawrence Kersta introduces voiceprint identification 0 cit. Bell Labs engineer Lawrence Kersta proposed that spectrographic analysis of a person's voice, which he called a voiceprint, could reliably identify individual speakers, drawing an analogy to fingerprints. Some police departments and courts began admitting voiceprint testimony, but later scientific review found the method lacked adequate validation and a demonstrated error rate. Courts became increasingly reluctant to admit voiceprint evidence as its scientific basis was questioned. science ●●

1962 Kuhn and the idea of scientific revolutions 0 cit. Thomas Kuhn argued that science does not just accumulate facts but lurches between paradigms, with old frameworks replaced in crises. His book made paradigm shift a household phrase and challenged the tidy story of steady progress. Critics warned his view could be pushed too far, into treating all theories as equally valid, which he did not intend. culture / science ●●

1962 Licklider imagines networked, interactive computing 0 cit. ARPA hired the psychologist J.C.R.

c. 1970 Peer review and science as a self-correcting process 0 cit. Formal peer review, where experts vet a paper before publication, became standard in most journals only in the middle of the twentieth century, later than many assume. It is a filter, not a guarantee of truth, and it misses errors and fraud. The deeper strength of science is that findings must survive repeated testing by others, so it corrects itself over time rather than resting on fixed truths. science / society ●●

April 1971 Salyut 1, the first space station 0 cit. The Soviet Union launches Salyut 1, the first space station, shifting the contest from the Moon to long-duration life in orbit. The USSR would lead in space stations for decades, culminating in Mir. science / technology ●●●

c. 1971 The Bantu problem: where did the expansion begin contested 0 cit. Malcolm Guthrie's four-volume Comparative Bantu mapped shared word-roots across hundreds of Bantu languages and argued the family radiated from a nuclear zone in the Congo woodlands. Greenberg's tree instead pointed to a West African origin. The clash became known as the Bantu problem, and the exact homeland and routes are still argued today. It shows how the same language data can be read toward different histories. science / society ●●●
