Radiometric dating of nearby rocks indicated the resulting skeleton, classified as Ardipithecus ramidus-nicknamed “Ardi”-was an astounding 4.4 million years old, more than a million years older than the world-famous “Lucy.” The team spent the next 15 years studying the bones in strict secrecy, all while continuing to rack up landmark fossil discoveries in the field and becoming increasingly ensnared in bitter disputes with scientific peers and Ethiopian bureaucrats.
