What is austrolopithecus?

An austrolopithecus is an early hominid (early ancestor of humans) that was mostly ape, but what distinguished them to be human is that they walked upright. They lived about 3.5 million years ago, and is the oldest known. You may also know of it as Lucy, discovered by Donald Johanson in the 1970s. Lucy was named after hearing the song Lucy in the Sky with Diamonds being played over and over again during the celebration for finding Lucy. Recently, they discovered a new hominid though and is something like Artolopithecus, something like that. Hope this helps!
