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]
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]
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]
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]
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.
Ethiopia is considered the area from which anatomically modern humans emerged. [1] Archeological discoveries in the country's sites have garnered specific fossil evidence of early human succession, including the hominins Australopithecus afarensis (3.2 million years ago) and Ardipithecus ramidus (4.4 million years ago).
Ardipithecus Ardipithecus is, or may be, a very early hominin genus (tribe Hominini and subtribe Hominina). Two species are described in the literature: A. ramidus, which lived about 4.4 million years ago [32] during the early Pliocene, and A. kadabba, dated to approximately 5.6 million years ago [33] (late Miocene).
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.
