Ancient rock art uncovered in Saudi Arabia's Nefud Desert
Archaeologists have discovered over 170 monumental rock engravings in northern Saudi Arabia, dating back 12,800 to 11,400 years. These life-sized animal depictions, created after a period of extreme aridity, highlight early human adaptation in the desert. The findings reveal connections to distant Neolithic communities and underscore a lost cultural identity.
Human skulls evolved faster than those of other apes
Researchers at University College London have discovered that human skulls evolved at an exceptionally rapid pace compared to other apes, developing larger brains and flatter faces twice as quickly as expected. This acceleration likely stems from cognitive and social evolutionary pressures. The findings, based on 3D skull models, highlight unique human adaptations among great apes.
Genetic change protected early humans from lead's evolutionary impact
Researchers have uncovered evidence that ancient hominids were exposed to lead as early as two million years ago, potentially influencing brain evolution. Modern humans possess a unique genetic variant in the NOVA1 gene that shielded them from lead's toxic effects on language development. This discovery, published on October 15, 2025, suggests it gave Homo sapiens an advantage over Neanderthals.
Scientists prove moai statues walked using rocking motion
Researchers have confirmed that ancient Rapa Nui villagers moved massive moai statues upright using ropes and a rocking technique. Experiments with replicas and 3D models demonstrate the feasibility of this method, resolving a centuries-old mystery. The findings highlight the ingenuity of the island's people with limited resources.
