Ardipithecus ramidus is a species of australopithecine from the Afar region of Early Pliocene Ethiopia 4.4 million years ago (mya). A. ramidus , unlike modern hominids , has adaptations for both walking on two legs ( bipedality ) and life in the trees ( arboreality ).
Ardipithecus is a genus of an extinct hominine that lived during the Late Miocene and Early Pliocene epochs in the Afar Depression, Ethiopia.Originally described as one of the earliest ancestors of humans after they diverged from the chimpanzees, the relation of this genus to human ancestors and whether it is a hominin is now a matter of debate.

Ardi (ARA-VP-6/500) is the designation of the fossilized skeletal remains of an Ardipithecus ramidus, thought to be an early human-like female anthropoid 4.4 million years old. It is the most complete early hominid specimen, with most of the skull, teeth, pelvis, hands and feet, [ 1 ] more complete than the previously known Australopithecus ...
Despite extensive research, no direct fossil evidence of the CHLCA has been discovered. Fossil candidates like Sahelanthropus tchadensis, Orrorin tugenensis, and Ardipithecus ramidus have been debated as either being early hominins or close to the CHLCA. However, their classification remains uncertain due to incomplete evidence
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
Tim D. White (born August 24, 1950) is an American paleoanthropologist and Professor of Integrative Biology at the University of California, Berkeley.He is best known for leading the team which discovered Ardi, the type specimen of Ardipithecus ramidus, a 4.4 million-year-old likely human ancestor.
If the resulting moral injury is largely invisible to outsiders, its effects are more apparent. “I would bet anything,” said Nash, the retired Navy psychiatrist, “that if we had the wherewithal to do this kind of research we’d find that moral injury underlies veteran homelessness, criminal behavior, suicide.”
