'''Ardipithecus ramidus''' is an example of the earliest known [[hominin]]s.  According to [[secular]] science, members include humans and their ancestors that date to approximately 4.4 million years ago.  <ref>http://www.sciencemag.org/cgi/content/full/326/5949/36</ref>  [[Creation scientist]]s disagree with this dating,<ref>http://www.answersingenesis.org/articles/nab/does-radiometric-dating-prove</ref> citing the [[Radiometric_dating#Acceptance_and_reliability|unreliability]] of the methods used to arrive at such a figure.<ref>http://creation.com/radioactive-dating-failure</ref>

According to ''Science'' magazine, ''ardipithecus'' is not the oldest putative hominin, but it is by far the most complete of the earliest specimens. The most recent find includes most of the skull and teeth, as well as the pelvis, hands, and feet and reveal an "intermediate" form of upright walking, considered a hallmark of hominins.  Paleoanthropologist Andrew Hill of Yale University is quoted as saying, "We thought Lucy was the find of the century but, in retrospect, it isn't."  <ref>http://www.sciencemag.org/cgi/content/full/326/5949/36</ref>

There is not yet a consensus on the validity concerning the ability of Ardipithecus to walk upright as some anthropologists are stating there is only circumstantial evidence for upright walking.  Debate about Ardipithecus's locomotion and identity evolves but she provides the first hard evidence about the ancient hominins. <ref>http://www.sciencemag.org/cgi/content/full/326/5949/36</ref>
