Eldest human ancestor has Lucy beat at 3.4 million years old
Chris Burns - May 27, 2015
The fossilized remains of a jaw and teeth are discovered near the origin of the previous eldest human ancestor, Lucy. This jaw belonged to a species by the name of Australopithecus deyiremeda. This species would have existed between 3.3 and 3.5 million years ago, putting it at an age when Lucy’s species Australopithecus afarensis could have walked the Earth. This oldest species is now one of three species that existed in eastern Africa more than 3 million years ago more closely related to humans than to chimps. The third was Kenyanthropus platyops, having lived in Kenya at roughly the same time.
Speaking on the release of the paper that surrounds this find as published in Nature this week, Yohannes Haille-Selassie, palaeoanthropologist at the Cleveland Museum of Natural History in Ohio said “the question that is going to come up is which taxa gave rise to our genus, Homo.”
“That’s going to be the 64-million-dollar question.”

The upper and lower jaw were found all the way back in March of 2011. When these pieces of history were found, “that forced us to extend our stay,” said Haille-Selassie.

“We’re convinced this is different from all the species we know,” said Haille-Selassie. This research team originally suspected the bones belonged to Lucy’s species, when in fact they had features different enough from that one species to belong to another.
The team hopes to link the jaw pieces to a set of foot fossils found earlier in Woranso-Mille. If they are linked, the case for a third species of this age will be made stranger than it already is.
Below you’ll see a basic chart showing the ancestry of our Homo Sapien classification and the rest of our related cousins from throughout history.

This paper was authored by Yohannes Haile-Selassie, Luis Gibert, Stephanie M. Melillo, Timothy M. Ryan, Mulugeta Alene, Alan Deino, Naomi E. Levin, Gary Scott, and Beverly Z. Saylor.

INI LUCY
Who is Lucy the Australopithecus? Five facts you probably didn't know about oldest hominin ever discovered
Lucy has been honoured with a Google Doodle on the 41st anniversary of her discovery

The 41st anniversary of the discovery of 'Lucy' has been celebrated with a Google Doodle.
'Lucy' is a collection of fossilised bones that once made up the skeleton of a hominid from the Australopithecus afarensis species. She lived in Ethiopia 3.2 million years ago.
First discovered in 1974, the discovery was remarkably 'complete' - 40 per cent of her skeleton was found intact, rather than just a handful of incomplete and damaged fossils that usually make up remains of a similar age.
Shortly after being dug up, it became apparent that Lucy was a significant find with researchers saying she belonged to a previously unknown species.
In honour of 'Lucy', here are five things you may not know about her:
1. She was named after The Beatles song 'Lucy in the Sky with Diamonds'
After making the discovery, paleoanthropologist Donald Johanson headed back to his campsite with his team.
He put a Beatles cassette in the tape player, and when Lucy in the Sky with Diamonds came on, one of the group said he should call the skeleton Lucy.
"All of a sudden, she became a person," Johanson told the BBC.

Who is Lucy the Australopithecus: How related are you to the 3.2 million-year-old hominid?
Despite looking drastically different to modern humans, Australopiths like Lucy walked upright and even used tools

Despite her short stature and hirsute frame, Lucy the Australopithecus afarensis, whose discovery is today commemorated with a Google Doodle, was from a species that could be a forerunner to modern humans.
As her named suggests, Lucy came from the Australopithecus genus, and was a member of the Hominini tribe, just like us.
Lucy was one of the later Australopiths, and is believed to have lived in what is now Ethiopia around 3.2 million years ago - roughly 800,000 years after her species first evolved.
Although the remains of Lucy are currently held in the National Museum in Addis Ababa, not far from where she was found, other members of her species were much better-travelled - animals from the same genus spread throughout Africa, before becoming extinct around 2 million years ago.
Despite our obvious differences, modern humans and Lucy have one important similarity - we both walk upright.
Bipedal movement is a very human quality, and scientists immediately recognised that Lucy could walk after studying the structure of her knees and the shape of her spine.
It's widely believed that one Australopithecus genus was the ancestor of the Homo genus, which comprises modern humans, as well as now-extinct species like Homo habilis and Neanderthal man.
However, it's not known for sure which Australopithecus species gave rise to Homo - but since Homo evolved around 2.8 million years ago, it's possible that our two species are related in some way.
At her discovery, it was thought that Lucy could be the oldest direct ancestor of modern humans - another stepping-stone towards the 'missing link', the common ancestor we share with chimpanzees.
It's since turned out that we probably split from chimps much earlier, maybe as early as 13 million years ago.
There were many different hominid species living around this period, often interacting or even breeding with each other, making it hard to find our true common ancestor.
At any rate, the discovery of Lucy's two-legged walking and her well-preserved remains brought us one step closer to understanding where we came from.
