The human ability to walk and run efficiently on two feet arose around 2 million years ago with our Homo erectus ancestors. But our earlier relatives, the australopithecines, were also bipedal around 4 million years ago. Given the long arms and different body proportions of species like Australopithecus afarensis, though, researchers have assumed that australopithecines were less capable of walking on two legs than modern humans.
In a study published online Dec. 18 in the journal Current Biology, a team of researchers modeled the skeletal and muscular anatomy of Lucy to determine her maximum running speed, the energetic costs associated with running, and her running endurance.

Australopithecines like Lucy had large upper bodies, long arms and short legs, which likely limited their running speed. But the researchers discovered that another potential reason for Lucy's slow, inefficient running may have been a differently shaped Achilles tendon and triceps surae, a group of muscles in the calf.
Modern humans have a long, spring-like Achilles tendon, the researchers noted, which connects calf and ankle muscles to the heel bone. This anatomical arrangement provides humans with the powerful and efficient ankle crucial to high running performance.

Except the species Lucy was from was bipedal.
There is no such thing as a missing link. All species are transitional.
The theory of Macroevolution is seriously flawed. If you have not read the work of Michael Behe or Steven C. Meyer (former athiests) regarding this, I suggest you do.
Lucy is a fiction made of up of unrelated parts.
Parts they found scattered over two miles I believe.
Must have not run fast enough to escape the prehistoric laughing hyena’s jaws.
Many years after the entire “Lucy” fraud being debunked, there are still “scientists” pretending Lucy represents a missing link in human “evolution”... Yet another reminder of how corrupt and untrustworthy “science” can be.
And all this “Lucy” physiology... from a part of a skull... LOL
Jimmy the Greek was right; they have an extra bone in their foot!
“I don’t think that early humans needed to run from much since They were much more powerful than modern humans.”
Early “humans” were dinner to lions!
And early humans wore lion pelts and lion tooth jewelry.
Lucy was bad at holding a football for a kicker too.
But I digress.....
“The theory of Macroevolution is seriously flawed. If you have not read the work of Michael Behe or Steven C. Meyer (former athiests) regarding this, I suggest you do.”
Both are evolution proponents.
“And early humans wore lion pelts and lion tooth jewelry.”
In honor of their buddies that died in the quest.
No. That’s not true at all.
Nothing in your comment is accurate.
Don’t think he said anything about extra bones.
Human ancestor? In other words, “Blah, blah, blah.”
Don Johanson’s hoax lives on. boy, 50+ years, paleontology truly is ‘money for nothin and your chicks for free.’
