The 1959 discovery of the OH 5 skull led to the first K-Ar age determination of sediments at Olduvai by Garniss Curtiss. Finding them to be 1.75 Ma—triple the expected age—he wrote: "One thing is certain. Olduvai Man is old, old, old!"

An approximately 1.9-million-year-old fossil from Swartkrans, South Africa, attributed to the genus Homo is one of the first to have dental abcesses, which affect the tips of its incisor roots.

The most well-preserved evidence of the brain of comes from the DH3 partial skull. At 450 ml, this fossil's endocranial volume is around one third the size of the average living human, but shares some aspects of frontal lobe form.

Skull 3 from Dmanisi is one of the most complete cranial remains attributed to Homo erectus. This individual represents a stage of development just before adulthood, with third molars just beginning to erupt.

Recent work by Yolanda Fernández-Jalvo and Peter Andrews found that cranial fractures on the Spy 1 Neandertal skull were the likely cause of death of this individual. A new dating scheme places the Spy Neandertals between 44,300 and 40,700 years ago.

Even small fragments of Homo erectus skulls are often very recognizable, due to their thick cranial bone and prominent, thickened entheses. This skull fragment existed at a time of faunal interchange between Java and mainland Asia.

One of the beautiful fossils found in South Africa during the last few years is the DNH 155 skull, reconstructed by . This Paranthropus robustus individual lived sometime around 2 million years ago.

Homo antecessor is a species that occupies a fascinating time and place in human origins. The material from Gran Dolina are the closest known sister group to the common ancestor of today's people, Neandertals, and Denisovans.

The most complete skeleton attributed to Australopithecus afarensis is the young child from Dikika, Ethopia. This had a hyoid bone similar to chimpanzees and gorillas, suggesting apelike vocal communication.

The skull from Hexian, China, is a Homo erectus individual from around 410,000 years ago, who suffered soft tissue injuries to his or her scalp—in today's people consistent with injury from extreme hair pulling or burns.

The fossils from Caune de l'Arago, France, are around the same age as the large Sima de los Huesos sample of early Neandertals. Whether they represent the same population is not clear. They test our ability to determine relationships with morphology.

KNM-ER 992 was one of the fossils discovered by Richard Leakey's field team that were claimed as holotypes for species named by other scientists: in this case Homo ergaster. This "taxonomic scramble" of the 1970s and 1980s left a harmful legacy in

The "Ardi" skeleton from Aramis, Ethiopia, provides the most complete cranial, dental, and postcranial evidence of any hominoid from the Early Pliocene. Some of its features point to a relationship with later remains.

The variability of the fossils from Hadar, Ethiopia, has long been attributed to sexual dimorphism and temporal trends within Australopithecus afarensis. The recent discovery of other species at nearby sites may require re-evaluation of this idea.

The MLD 40 jaw is one of the larger ones attributed to Australopithecus africanus. Raymond Dart thought that it was a victim of cannibalism, but it lacks the evidence that we look for today to identify this behavior.

A child's skull from Herto, Ethiopia, appears to document a mortuary practice involving the long-term keeping and handling of human remains, more than 147,000 years ago. Cultural observance of death may go back much further in ancestry.

Léon Henri-Martin found the humerus of a Neandertal partial skeleton in 1911 at La Quina. He wrote, "The fragility and powdery state of the upper right maxilla made three teeth fall into my hands."

One of the first known mandibles of Homo erectus was this left side of a jaw from Zhoukoudian, China, found in 1931. Many jaws discovered later would come to be called H. erectus because of similarity to this individual.

Textbooks often treat Homo habilis as a common ancestor for all later species in our genus. But the OH 7 mandible shows that this may have evolved quite differently from other members of Homo.
