Discovery of a Lucy , a 3.2 million -year-old skeleton, changed our theory of human evolution forever.

The 'March of Progress' chart of evolution was based on a series of stages which took place over millions of years .

Early theorists thought our ancestors' brains grew steadily larger as they started walking on two legs and standing taller until they became modern humans.

A better way to think about human evolution is like a 'bushy tree' with many branches.

As for Lucy 's legacy, her discovery is now like a mascot for evolution. It was a flashy finding which, along with lots of other data, helped develop a better theory of how our species came to be. "Back in the 70s , when Lucy was found, it was such a singular discovery. It is probably the most recognized specimen [and] the name has always helped in that regard, because everyone remembers it," Herries said.
