Fungus-farming termites descend from an African rain forest Eve

...d tropics, from Africa to Asia. But as researchers report this week, a combination of DNA sequence analysis and computer modelling suggests that termite agriculture originated in the African rain forest, and gave rise to the many fungus-cultivating termite species alive today in various parts of the Old Wor...
