Ardipithecus kadabba is the scientific classification given to fossil remains "known only from teeth and bits and pieces of skeletal bones", [1] originally estimated to be 5.8 to 5.2 million years old, and later revised to 5.77 to 5.54 million years old. [2]
Discovery of Ardipithecus kadabba (2004) 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.
A. kadabba is considered to have been the direct ancestor of A. ramidus, making Ardipithecus a chronospecies. [7] The exact affinities of Ardipithecus have been debated. White, in 1994, considered A. ramidus to have been more closely related to humans than chimpanzees, though noting it to be the most ape-like fossil hominin to date. [1]
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 ...
Ardipithecus kadabba fossils. Ardipithecus kadabba is "known only from teeth and bits and pieces of skeletal bones", [14] and is dated to approximately 5.6 million years ago. [3] It has been described as a "probable chronospecies" (i.e. ancestor) of A. ramidus. [3]
Dated to 3.7 million years ago, they were the oldest known evidence of hominin bipedalism at that time. Subsequently, older Ardipithecus ramidus fossils were found with features that suggest bipedalism. With the footprints there were other discoveries excavated at Laetoli including Hominina and animal skeletal remains.

Ardipithicus kadabba was discovered in 1997 on the Western Side, at site Asa Koma, [8] by Yohannes Haile Selassie and Giday WoldeGabriel. Ardipithecus kadabba is one of the earliest known hominids from the Late Miocene period. It was first announced in 2001, and further remains were announced in 2004. [8]
