That’s a chimp. I heard about “Lucy” all those years, and the first “humans” bla bla bla ad nauseum for 20 years in National Geographic.
Then one day, I saw a scale model of “Lucy” in a museum. All I could think was “dammit, the SOBs tricked me again. That’s a chimp of some sort and that’s all”.
No. A chimp from the waist up, maybe, but the arm bones were human like (much longer, in proportion to a chimp, gorilla or orangutan—human proportioned), and she had a definitive pelvis and long human legs with kneecaps, ending in flat human feet.
What ever Lucy was, she wasn’t a chimp.
Dr. Don Johanson recovered almost all of her skeleton.
