It is remarkable that the taxonomy and phylogenetic relationships of the earliest known
representatives of our own genus, Homo, remain obscure. Advances in techniques for …

In this review of the evidence for and against taxic diversity within the hominin clade, we
begin by looking at the logic and the history of simple “ladder‐like” interpretations of the …

A new statistical method for estimating divergence dates of species from DNA sequence
data by a molecular clock approach is developed. This method takes into account effectively …

Our understanding of the origin of the genus Homo has been hampered by a limited fossil
record in eastern Africa between 2.0 and 3.0 million years ago (Ma). Here we report the …

The postcranial skeleton of Australopithecus afarensis from the Hadar Formation, Ethiopia,
and the footprints from the Laetoli Beds of northern Tanzania, are analyzed with the goal of …

The earliest hominin occupation of Europe is one of the most debated topics in
palaeoanthropology. However, the purportedly oldest of the Early Pleistocene sites in …

The cerebral cortex, occupying over 70 percent of our brain mass, is key to any
understanding of the workings--and disorders--of the human brain. offering a …

Current consensus holds that the 3-million-year-old hominid Australopithecus africanus
subsisted on fruits and leaves, much as the modern chimpanzee does. Stable carbon …

Numerous studies use estimates of sexual dimorphism in canine tooth size and body weight
to support speculation about the behavior of australopithecines. However, the range of …

The living hominoid primates are Man, the chimpanzees, the Gorilla, the Orangutan, and the
gibbons. The cercopithecoids (Old World monkeys) are the sister group of the hominoids …
