 Branchless Evolution: Fossils point to single hominid root: Science News Online, April 15, 2006
A team led by anthropologist Tim D. White of the University of California, Berkeley unearthed 31 fossils of Australopithecus anamensis, the earliest known species of this ancient hominid genus.
anamensis lived in the same place and negotiated comparable habitats, it's plausible that the earlier hominid evolved directly into the later one, remarks anthropologist Alan C. Walker of Pennsylvania State University in University Park, a member of the team that found Au.
anamensis branched from an earlier, as-yet-unknown population would require evidence that the Australopithecus species lived at the same time as Ar.

 Anthropologists find 4.5 million-year-old hominid fossils in Ethiopia
In the 11 years since the naming of A. ramidus by University of California Berkeley anthropologist Tim White and colleagues, only a handful of fossils from the species have been found, and only at two sites -- the Middle Awash and Gona, both in Ethiopia.
Anthropologists working in Ethiopia believe Ardipithecus is the first hominid genus -- that is, human ancestors who lived just after a split with the lineage that produced modern chimpanzees.

 03.04.2004 - New Ethiopian fossils are from 6-million-year-old hominid living just after split from chimpanzees
Haile-Selassie and coauthors Tim White of UC Berkeley and Gen Suwa of the University Museum at the University of Tokyo report their fossil finds in the March 5 issue of the journal Science.
Anthropologist Owen Lovejoy proposed in the 1980s that reduced canines among early hominids showed that males had become more involved in the parenting process, and that the carrying of infants and food was strong selective pressure toward a musculoskeletal system adapted to walking on two legs.
The implication of this dental difference is that the newly evolved hominids were living in a radically different, less competitive social structure than seen in modern chimps, he said.

As Tim White suggests, “Why confuse your students with this?
Citing differences in cranial capacity (1470’s cranial capacity is 775 cc’s, while other habilis skulls are in the 550 cc range), and dental pattern, Russian anthropologist Valerii Alexeev pulled 1470 from habilis and renamed it Homo rudolfensis (Johanson 1996).
Whether 1470 was a habilis or a rudolfensis should not be the focus in a classroom.

 LiveScience.com - Fossil Find Improves Knowledge of Human Origins
“This discovery fills the gap between Ardipithicus and Australopithecus,” said study team member Tim White, an anthropologist at the University of California, Berkeley.
Anamensis bones found at Asa Issie included a femur, several teeth and the largest jaw fragment ever recovered from any hominid.
Newfound fossils from Ethiopia are giving scientists a clearer glimpse into the murky origins of a hominid species that was an important link in the evolution of ape to man.

 Neandertal News
According to Tim D. White of the University of California at Berkeley, who has studied the bones, and French archaeologist Alban Defleur of the University of the Mediterranean, Marseilles, who has excavated the site since 1991, cut marks on the bones could have been made only by sharp flints.
Undertaken by physical anthropologist Alan Mann and a team of researchers from the University of Pennsylvania, the study of 884 bone fragments belonging to some 75 individuals showed that the Neandertal population was "osteologically healthy" aside from suffering from normal biomechanical wear due to day-to-day activities such as food-getting, aging, and injury.
The 78 bone fragments, which have been dated at between 80,000 and 120,000 years ago, appear to have come from at least six individuals--two adults, two teenagers about 16 or 17 years old, and two children aged six or seven.
