How gene loss and monogamy built termite mega societies

Termites did not evolve complex societies by adding new genetic features. Instead, scientists found that they became more social by shedding genes tied to competition and independence. A shift to monogamy removed the need for sperm competition, while food sharing shaped who became workers or future kings and queens. Together, these changes helped termites build colonies that can number in the millions.
