Is Lucy an ape or human?

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). Discovered in 1974 by paleontologist Donald C. Johanson in Hadar, Ethiopia, A.

Why is Lucy Australopithecus afarensis important?

Lucy was one of the first hominin fossils to become a household name. Her skeleton is around 40% complete - at the time of her discovery, she was by far the most complete early hominin known. ... A cast of Lucy, the partial skeleton of an Australopithecus afarensis female found at Hadar, in the Afar region of Ethiopia.

What is Australopithecus known for?

Australopithecus afarensis is one of the longest-lived and best-known early human species—paleoanthropologists have uncovered remains from more than 300 individuals! ... They also had small canine teeth like all other early humans, and a body that stood on two legs and regularly walked upright.

Is Australopithecus afarensis extinct?

Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa. The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s.

Is Australopithecus a human ancestor?

The fossil record seems to indicate that Australopithecus is ancestral to Homo and modern humans. ... Earlier fossils, such as Orrorin tugenensis, indicate bipedalism around six million years ago, around the time of the split between humans and chimpanzees indicated by genetic studies.

What was Lucy's cause of death?

There are indications of degenerative disease to her vertebrae that do not necessarily indicate old age. It is believed that she was a mature but young adult when she died. In 2016 researchers at the University of Texas at Austin suggested that Lucy died after falling from a tall tree.

What feature found in Australopithecus afarensis was most significant to our understanding of human evolution?

The footprints are of major significance as they are the first direct evidence (ie not fossils bones) that our ancestors were walking upright by 3.6 million years ago. The fossil footprints are very similar to our own footprints. They show that the heel was the first part of the foot to strike the ground.

Why is 1974 fossil called Lucy?

"Lucy" acquired her name from the 1967 song "Lucy in the Sky with Diamonds" by the Beatles, which was played loudly and repeatedly in the expedition camp all evening after the excavation team's first day of work on the recovery site.

What is a derived feature of Australopithecus afarensis?

Derived features, such as thick enamel, intermediately sized molars, and reduced canines are also hallmarks of Au. afarensis1. The lower limbs clearly show this species was bipedal, while the upper limb morphology suggests Au. afarensis may have continued to practice some form of arboreality.

What is the difference between Australopithecus and Neanderthal?

Australopithecus walked upright but had small brains and didnt use tools. Neanderthal used tools, made clothes from animal skins and were the first to bury their dead.

What led to the extinction of Australopithecus?

One certain reason why the Australopithecines went extinct, it is that they were unable to survive under the competitive living circumstances of the time. They were believed to have been overtaken by more efficient herbivores such as the gazelle, oryx, and the horse.

Which is older afarensis or africanus?

africanus. At the time, these remains were dated to 3.3 million years ago in the Late Pliocene. In 2019, Clarke and South African palaeoanthropologist Kathleen Kuman redated StW 573 to 3.67 million years ago, making it the oldest Australopithecus specimen from South Africa. ... afarensis from Middle Pliocene East Africa.

Why Australopithecus afarensis is extinct?

All the australopithids went extinct by about 1 million years ago, about 3 million years after they first appeared. Habitats may have vanished as a result of global climate cooling -- or the australopithids may have been pressed to extinction by the growing populations of early humans.

How did Ardi get around?

Ardi's Weird Way of Moving All previously known hominids—members of our ancestral lineage—walked upright on two legs, like us. But Ardi's feet, pelvis, legs, and hands suggest she was a biped on the ground but a quadruped when moving about in the trees.

Is Lucy the oldest human?

Lucy's Ethiopian name is Dinkinesh, which translates to “you are marvelous.” Peoples of the Afar region call Lucy “Heelomali” which means “she is special.” At the time of Lucy's discovery, she was a shining star in the world of paleoanthropology: she was the oldest, most complete hominin skeleton ever discovered; she ...

Why did Australopithecus go extinct?

All the australopithids went extinct by about 1 million years ago, about 3 million years after they first appeared. Habitats may have vanished as a result of global climate cooling -- or the australopithids may have been pressed to extinction by the growing populations of early humans.

Who was the first human on earth?

Homo habilis The First Humans One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.

Who found Lucy's bones?

Donald Johanson The team that excavated her remains, led by American paleoanthropologist Donald Johanson and French geologist Maurice Taieb, nicknamed the skeleton “Lucy” after the Beatles song “Lucy in the Sky with Diamonds,” which was played at the celebration the day she was found.

What are the characteristics of Australopithecus africanus?

africanus had a rounder cranium housing a larger brain and smaller teeth, but it also had some ape-like features including relatively long arms and a strongly sloping face that juts out from underneath the braincase with a pronounced jaw. Like Au. afarensis, the pelvis, femur (upper leg), and foot bones of Au.

Which of the following is a trait of Australopithecus afarensis quizlet?

afarensis had both ape and human characteristics: members of this species had apelike face proportions (a flat nose, a strongly projecting lower jaw) and braincase (with a small brain, usually less than 500 cubic centimeters -- about 1/3 the size of a modern human brain), and long, strong arms with curved fingers ...
