Archaeologists have found evidence of Homo sapiens in the Qesem Cave in Israel dating back to 400,000 years ago. The discovery challenges the long-held theory that modern man emerged from Africa 200,000 years ago and may indicate significant evolutionary changes in human behavior during this period.
The discovery of the ancient Siberian human genome reveals a new hominin group, Denisovans, which shared an origin with Neandertals but diverged. The findings also suggest interbreeding between Denisovans and modern human ancestors in Papua New Guinea.
New research in Psychological Science found that the fear of being the target of malicious envy motivates people to act more helpfully toward those they think might be jealous. This fear encourages prosocial behavior, such as sharing resources with others.
Research shows that young children are sensitive to others' moral behaviors and intentions, helping less when they see harm or intention behind an action. This suggests children's moral development is more complex than previously thought.
Researchers found that up to 53 out of 128 studied societies believe in the principle of multiple paternity. Women benefit from this system as secondary fathers provide gifts and support, increasing child survival rates. Men also gain by formalizing alliances through shared wives, strengthening family bonds.
A recent study found that the brains of newborn humans and Neanderthals are similar in size and appearance, but differ significantly in shape after birth. The differences reflect changes in brain circuitry and may underlie cognitive differences between the two species.
A team of researchers has uncovered well-dated human fossils in southern China, pushing back the known emergence of modern humans by at least 60,000 years. The discovery indicates that early modern humans co-existed with late archaic humans for tens of millennia across Eurasia.

Researchers used mitochondrial DNA samples from living animals, skeletons, and archaeological sites to trace the family trees of the domestic donkey.
Paleoanthropologist Pat Shipman suggests that humans' ability to nurture other animal species contributed to the development of language and tool-making, ultimately leading to domestication. This 'animal connection' allowed early humans to develop a system of communication and observation, which became increasingly advantageous over time.

A study using African Americans with West African and European ancestry found a strong statistical correlation between genetic admixture and facial traits. The researchers measured distances between specific face landmarks to compare genetically determined admixture with facial feature differences.
Human mothers with social support can conserve energy, allowing their bodies to prepare for the next pregnancy. In contrast, nonhuman primates lack this flexibility and have relatively low reproductive rates due to similar energy demands during lactation. Social support plays a crucial role in human reproductive success.
Rafe Sagarin, a Duke University ecologist, advocates for a Darwinian approach to homeland defense, emphasizing adaptability and responsiveness over rigid security measures. By learning to live with threats rather than eliminating them entirely, organisms can better handle unforeseen risks in an escalating arms race.
Researchers at ASU have discovered that humans have a unique genetic adaptation to starch consumption, with high-starch diets associated with more copies of the AMY1 gene. This finding provides insight into why certain populations may be better equipped to handle diarrheal diseases.
Researchers from Max Planck Institute and 454 Life Sciences Corp. have completed a draft version of the Neandertal genome, providing insights into their genetic relationship with modern humans. The study reveals significant differences between the Neandertal and human genomes, shedding light on how our species diverged.
Recent findings suggest early humans primarily ate gelatin, contradicting the long-held notion that they ate hard, tough foods like nuts. This shift in understanding may be linked to crisis situations rather than everyday dietary needs.
Researchers are using stable isotope analysis to reconstruct the past lives of hominids, revealing their diets and environments. The study of Paranthropus robustus suggests a diverse diet that includes hard foods like nuts, as well as sedges, grasses, seeds, and possibly animal foods.
Human ancestors' large brains required high-energy diets, while modern humans consume more calories and nutrients. The imbalance between energy intake and expenditure contributes to obesity worldwide.
Researchers used finite element analysis to determine the forces and stresses involved in chewing food, contradicting previous classical analyses. The study suggests that Australopithecus africanus may have eaten larger hard objects, such as nuts, due to their fracture properties rather than wear patterns.
A new study from the University of Minnesota suggests that smaller chimpanzees use political behavior, such as grooming, to secure top positions rather than relying on physical aggression. This finding is based on 10 years of observations of dominant male chimpanzees in Gombe National Park, Tanzania.
The Supe people's advanced stone pyramid temples and maritime farming community were devastated by a series of earthquakes and flooding caused by El Nino events, rendering their fertile fields and bays uninhabitable. The region's collapse serves as a cautionary tale for modern times, highlighting the risks of environmental vulnerability.
A study published in BMC Evolutionary Biology found that animal species sleeping for longer periods have reduced parasite infestation and increased immune cells. This suggests that sleep plays an important role in protecting animals from parasitic infections.
