Why longer thumbs in primates were pivotal to human evolution
Briefly

Coverage spans reproductive rights, climate change, Big Tech, investigative financial reporting, and documentary production. Donations fund journalists to report on-the-ground, present multiple perspectives, and keep reporting accessible without paywalls. The outlet states that quality journalism should be available to everyone and funded by those who can afford it. Scientists analyzed 94 fossils and living primate species, from lemurs to Neanderthals, examining thumb length, gripping ability, and brain size. The analysis found a persistent correlation between longer thumbs and larger brains across primates, with the association remaining even after removing human data, linking manual dexterity to cognitive evolution and technological, cultural, and geographic expansion.
Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging. At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
Scientists studied 94 fossils and living animals to understand how our ancestors developed their gripping abilities. The study, published in the journal Communications Biology, looked at primate species from lemurs to neanderthals and found the brain co-evolved with manual dexterity to help with gripping small objects. Large brains and dexterous hands are considered pivotal in human evolution, together making possible technology, culture and colonisation of diverse environments, the research authors said.
