3D motion capture shows no innate arm dominance during plain reaching or with added wrist weight; a lightweight stick strapped to the forearm reveals a dominant-hand gap, while writing with elbows eliminates it—demonstrating that handedness arises from lifelong tool-use practice and can be reshaped through targeted training, challenging the idea of fixed, biology-driven dominance.
Bumblebees solved a tool-use task by rolling a ball to reposition it under a ceiling-held artificial flower, with 75% success in the basic version and 23 of 30 in a more complex setup, showing flexible problem solving in miniature brains and challenging the view that insects act purely on instinct (study published in Science).
A new study in the Journal of Human Evolution reports that Neanderthals used rhinoceros teeth as hammers and anvils to shape stone and process materials. Wear patterns on fossil teeth from sites in Spain and France match experimental results using modern rhino teeth, suggesting deliberate, task-specific tooth selection rather than opportunistic use, and hinting at higher cognitive capabilities in Western Europe’s Middle Paleolithic.
New research shows Neanderthals in ancient France and Spain recycled rhinoceros molars into multipurpose tools used to shape stone, process hides, and manipulate plant fibers. Wear patterns on 281 fossilized rhino teeth, plus experiments using real rhino teeth, indicate these were functional tools, highlighting Neanderthals’ sophisticated technology and cognitive abilities.
Bruce, a kea missing his upper beak, becomes the dominant male in his Willowbank Wildlife Reserve group by pioneering a beak-jousting technique, winning all 36 of his 162 documented male-male interactions, and prompting researchers to highlight keas' problem-solving and the welfare implications of prosthetics for disabled animals.
An Austrian cow named Veronika learned to use a broom as a tool to scratch hard-to-reach areas, with researchers documenting 76 tool‑use instances across seven trial sessions. The finding challenges assumptions about cattle intelligence and suggests cows may be capable of innovative problem‑solving and tool use under stimulating conditions.
Ancient stone tools found in Kenya date back 3 million years, pushing back the origin of Oldowan technology and suggesting that multiple hominin species, including Paranthropus, used these tools for diverse food processing, which broadens our understanding of early human adaptation and dietary practices.
A 1.52 million-year-old fossil of Paranthropus boisei from Kenya reveals that this robust human ancestor had large, dexterous thumbs and foot structures supporting bipedal walking, indicating it could make and use simple tools, challenging previous assumptions that only Homo species used tools.
New fossils from Kenya reveal that Paranthropus boisei, previously thought to be a simple plant-eater, had human-like hands capable of gripping and a foot adapted for upright walking, challenging previous notions about its behavior and its relationship with early Homo species, and highlighting the complex, non-linear nature of human evolution.
Fossils of Paranthropus boisei from Kenya, dating 1.52 million years ago, reveal that this species had dexterous hands capable of gripping and possibly using tools, and feet adapted for upright walking, challenging previous notions of its capabilities and coexisting with early Homo species, thus reshaping our understanding of human evolutionary development.
First hand fossils of the extinct human relative Paranthropus boisei were discovered in Kenya, revealing surprising dexterity and gorilla-like grip features, suggesting potential tool use and complex manipulation abilities, challenging previous assumptions about early hominin capabilities.
The study finds a significant correlation between relative thumb length and brain size across 95 primate species, supporting the idea that neural and bodily adaptations coevolved to enhance manual dexterity, with implications for understanding human evolution and tool use.
Jane Goodall's pioneering 1960 study of wild chimpanzees in Tanzania revolutionized our understanding of animal behavior, revealing their complex social bonds, tool use, and emotional similarities to humans, ultimately reshaping our view of human evolution and our connection to the animal kingdom.
A study in Science Advances reveals that early human ancestors, such as Australopithecus sediba and Homo naledi, combined tree climbing with advanced stone tool use earlier than thought, showing a complex, mosaic evolution of the human hand that supported both arboreal and terrestrial lifestyles, challenging the idea of a linear hand evolution from ape-like to human-like forms.
A study reveals that chimpanzees exhibit complex tool-use behaviors, suggesting that the cognitive abilities underlying human language and technology may have evolved before humans and apes diverged. Researchers observed chimps using hierarchical 'chunking' to organize actions into sequences, similar to humans. This behavior was documented in wild chimps cracking nuts with tools, indicating that such cognitive skills might be shared across other ape species. The study highlights the slow evolution of chimpanzee tool-use behaviors compared to rapid human technological advancements.
