Lucy, the Australopithecus specimen went through several date revisions since she was found.
Anthropologist Susan Martinez outlines the numerous times Lucy has been re-dated to fit with contemporary theories.
Looking back at human history is an optical illusion; new archaeological discoveries are always challenging what we already know, and constant revisions are being made.
A finding in France known as the Fontechevade Man has been estimated to be between 40,000 to 800,000 years old just based on readings of nitrogen levels alone.
Scientists have even resorted to using different levels of dating to counterbalance the levels of scatter that may occur from carbon dating.
The prevalence of scatter across these finds makes it no wonder why our lineage is so difficult to trace.
How is it that these figures come to be so slippery and hard to pin on a timeline?
