Lucy was
one of the first hominin fossils to become a household name

. It provided a detailed example of tooth development in a juvenile.
How did they discover Lucy?
Lucy was found by Donald Johanson and Tom Gray on November 24, 1974, at the site of Hadar in Ethiopia. … Johanson suggested taking an alternate route back to the Land Rover, through a nearby gully. Within moments, he spotted a right
proximal ulna
(forearm bone) and quickly identified it as a hominid.

Perhaps the world's most famous early human ancestor, the 3.2-million-year-old ape “Lucy” was
the first Australopithecus afarensis skeleton ever found
, though her remains are only about 40 percent complete (photo of Lucy's bones). … afarensis was for about 20 years the earliest known human ancestor species (Africa map).

Was Lucy a knuckle walker?
she had the morphology that was classic for knuckle walkers.”
Lucy herself wasn't a knuckle walker
, notes Richmond; rather, these wrist traits are a leftover from her knuckle-walking ancestors. Richmond and Strait report in the 23 March Nature that chimps, gorillas, and two early hominids–A. afarensis and A.
What adaptation did Lucy have and why is it an advantage?
Lucy
represented an evolutionary bridge

What killed Lucy the chimp?
The truth is that
no-one knows how Lucy died
. Given that she was on one of the islands that comprise the River Gambia National Park then disease, a fall, drowning, snake bite, being snatched by a crocodile, lightning strike or even depression, are each more likely causes of her death than being killed by poachers.
