We call them ‘man's best friend’, and the evidence supports it. Dogs have been found buried alongside humans in graves dating back 14,000 years. They appear in ancient art from every continent, and they feature in the mythology, religion and folklore of virtually every culture. Archaeological evidence shows they have helped us hunt, protected our homes, hauled our possessions, herded our livestock and provided companionship through the entirety of recorded history.
Archaic human parents had to look after helpless infants like modern day parents do, according to new research. Human babies are born less developed than those of other great apes, and so are unable to move as freely. A common result of this is deformational plagiocephaly, also called flat head syndrome. Professor Yousuke Kaifu at the University of Tokyo led a team which studied head shapes from scans of living infants, historical Japanese skeletal remains, fossilized specimens of Homo erectus and Homo floresiensis, and compared these to measurements of dry skulls from other great apes. Human head shapes across the ages, as well as the fossilized samples, exhibited a far wider range of deformation. The team sees this as evidence that archaic humans birthed helpless infants, with implications for childcare practices and potentially cooperative social behaviors dating back hundreds of thousands of years.
The discovery that remote Mediterranean islands were colonised before the invention of agriculture has upended long-standing views about the maritime capabilities of Europe’s last hunter-gatherers.
New evidence from Malta published today (28 July 2026) in PNAS Nexus now shows that these hunter-gatherers were engaging in repeated long-distance sea journeys of at least 100km, likely between Sicily and Malta for at least a millennium.
