Q. Recently, the world's oldest termite mound discovered in which country?
Answer:
South Africa
Notes: Scientists discovered the world’s oldest inhabited termite mounds in Namaqualand, South Africa. Known as 'heuweltjies' in Afrikaans, these mounds host the southern harvester termite, Microhodotermes viator. Radiocarbon dating reveals organic carbon dating back 13,000 to 19,000 years, and carbonate dating up to 34,000 years. These mounds are the oldest with both organic and inorganic carbon, formed during a wetter climate that allowed minerals like calcite and gypsum to dissolve, enriching groundwater.
