A new study found that a single embryonic rule regulates hominin tooth size, with variations in the expression of this rule accounting for differences in tooth size throughout human evolution. The researchers discovered that the inhibitory cascade pattern for adult molars is directly linked to the size of milk molars.
A study led by Dr Alistair Evans from Monash University has simplified the understanding of human tooth evolution, allowing for predictions on missing teeth. The 'inhibitory cascade' rule reveals a pattern in tooth size that was previously thought to be more complex.
Two new hominin fossils, a finger bone and a molar, were found in the Sterkfontein Caves, associated with early stone tools dating back 2.18 million years. The specimens possess intriguing features that raise more questions than answers.
Researchers studying 2-million-year-old human fossils from South Africa found that early hominins had hearing patterns resembling those of chimpanzees, but with slight variations. The discovery suggests that early humans may have had better hearing in certain frequency ranges than other primates.
A team of scientists has uncovered over 1,500 hominin fossils in a cave complex in South Africa, representing the largest and most complete set found to date. The discovery adds a new branch to the human family tree, with the fossils suggesting that Homo naledi was deliberately depositing its dead in the cave.
A fossil monkey specimen representing the earliest baboon ever found has been discovered in South Africa, dated between 2-2.36 million years ago. The partial skull confirms earlier suggestions that the fossil baboon species is closely related to modern baboons and may be the earliest known members of the Papio hamadryas species.
A new study by George Washington University researchers challenges the idea that early Homo genus evolved with an increase in body size. They found that early hominins were generally smaller than previously thought, and the increase in body size occurred later with H. erectus.

The study's findings support the idea that violence played a significant role in shaping human evolution.
A study published in PLOS ONE suggests that early hominins like Paranthropus boisei ate a diet of tiger nuts, fruits, and insects, providing enough nutrients for their large brains. The research calculates that a hominin could extract sufficient calories from tiger nuts in just two to three hours per day.
Researchers found that early humans focused on sites with abundant nutritious foods, including protein, fats, carbohydrates, and essential vitamins. These nutrient-rich locations allowed hominins to colonize the Atlantic fringe of north west Europe during warm periods.
A recent study using dental fossils suggests that the common ancestor of Neanderthals and modern humans diverged nearly 1 million years ago, contradicting previous molecular evidence. The researchers found no known hominin species matches the expected dental morphology of the last common ancestor.
A new study challenges traditional hypotheses on human evolution by suggesting that bipedalism emerged as a response to the terrain, rather than climate-driven vegetation changes. The research proposes that the development of upright gait was driven by the need for security and food in rocky outcrops and gorges.
A study led by Binghamton University anthropologist Rolf Quam analyzed two species of early human ancestor in South Africa, revealing a human-like malleus that suggests changes in the bone occurred early in human evolution. The findings provide new insight into human origins and may need to be updated to include changes in this bone.
A recent study led by Joseph Ferraro, Ph.D., sheds light on the diet and food acquisition strategies of early human ancestors in Africa. The research team found that hominins at Kanjera South, Kenya, relied on a combination of hunting and scavenging behaviors to acquire nutritious animal remains.
A 2-year-old hominin child's skull fragment unearthed in Tanzania shows signs of anemia-induced porotic hyperostosis due to a diet lacking in meat. The discovery suggests that meat consumption became essential for proper functioning, leading to brain development and evolution.
A special journal edition published by the University of Witwatersrand and the Palaeontological Scientific Trust (PAST) reveals groundbreaking findings on Homo habilis and its ecological pressures. The research, conducted over two decades at Olduvai Gorge in Tanzania, sheds new light on human evolution and technological development.
Researchers analyzed fossil teeth to determine the dietary preferences of three groups of hominins in South Africa. The study found that Australopithecus had a more varied diet than early Homo, while Paranthropus had a primarily herbivorous-like diet
A study published in Nature magazine found that Australopithecus sediba had a varied diet consisting of fruits, tree bark, nuts, leaves and sedges. The team's analysis suggests they lived in a forested margin near grasslands, contrary to previous research on other hominin species.
A study published in Nature reveals that Australopithecus sediba consumed between 95 and 100 percent forest-based foods, contradicting the assumption that early hominins ate a varied diet. This finding provides insight into the dietary habits of our ancestors and sheds light on why some species thrived while others became extinct.
Researchers have found a partial foot skeleton that belongs to an early human ancestor, distinct from Lucy's species and Ardipithecus ramidus. The Burtele foot shows unique characteristics, including an opposable great toe, suggesting the presence of multiple hominin species during the late Pliocene era.
The discovery of a partial foot skeleton from the Burtele hominin species has provided new insights into human evolution. The fossil's characteristics suggest that it was adept at moving around in trees and grasping items with ease. This finding adds complexity to our understanding of locomotion in human evolution.
The discovery of a 3.4 million-year-old foot fossil in Ethiopia confirms the coexistence of two human ancestor species with different locomotion methods. The analysis suggests that more than one species existed between 3 and 4 million years ago, challenging previous assumptions about human evolution.
Researchers describe the earliest complete fossil hominin hand post-dating stone tools, Australopithecus sediba's hand. The study reveals that it used its hand for arboreal locomotion but also showed human-like precision grips, a prerequisite for tool-making.
Researchers found that females preferred to disperse from their natal groups, similar to chimpanzees and human groups. The study suggests early hominins' social structure was not like that of gorillas.
Researchers used fossil finger ratios to estimate the social behavior of early humans and their extinct relatives. The study found that Neanderthals and early members of the human species had lower finger ratios, indicating high levels of prenatal androgens and competitiveness.
Researchers found bones bearing unambiguous evidence of stone tool use, including cut marks made while carving meat off the bone. The discovery provides the first evidence that Lucy's species, Australopithecus afarensis, used stone tools and consumed meat, shifting the known timeframe of a game-changing behaviour for our ancestors.
Researchers from Arizona State University analyzed fossilized animal bone fragments to find evidence of sharp-edged stones being used to remove flesh and marrow. This discovery pushes back the origins of technology and carnivory by 800,000 years.
