Researchers at a Spanish chimpanzee sanctuary handed quartz crystals to two groups of rescued chimps; the apes showed strong interest—dragging, examining, and even trading bananas or yogurt to recover the largest crystal—while others sorted crystals by type. García-Ruiz suggests chimps’ attraction to crystals may stem from their Euclidean geometry, hinting at ancient cognitive roots shared with humans.
A cleaner wrasse fish passed a revised mirror-self-recognition test, suggesting self-awareness may be more widespread in vertebrates. In the study, researchers marked the fish before introducing a mirror, and the fish began scraping off the perceived parasite after seeing its reflection—on average about 82 minutes later—while also engaging in behavior like carrying a shrimp to the mirror to probe how the reflection works. This contingency testing and self-directed tool use extend previous work from 2018, implying that self-awareness could have evolved in bony fishes and may have implications for evolution, animal welfare, and AI research; the findings are reported in Scientific Reports.
Researchers at Johns Hopkins conducted tea‑party–style tests with Kanzi the bonobo to test if apes can imagine pretend objects. He consistently indicated the locations of pretend juice and pretend grapes and could distinguish pretend from real items, suggesting that imagination and pretense are not uniquely human. The study, published in Science, argues that enculturated apes may have a mental life that extends beyond the present and lays groundwork for exploring future thinking and others’ minds in nonhuman primates.
Scientists have discovered that a select group of gifted dogs can learn the names of new toys by overhearing their owners talk about them, demonstrating advanced cognitive abilities similar to those seen in humans and some other animals.
Scientists trained bumblebees to distinguish between different durations of light patterns, similar to Morse code, demonstrating their ability to process temporal information and make decisions based solely on visual cues, revealing complex cognitive abilities in insects.
Alex the parrot, an African gray, revolutionized our understanding of animal intelligence through his ability to use words, ask questions, and demonstrate self-awareness, challenging previous beliefs about animal cognition and consciousness.
Jim Al-Khalili's 'Secrets of the Brain' explores 600 million years of brain evolution, highlighting the similarities between human and animal brains, and questioning what truly separates humans from other primates, emphasizing the importance of social complexity and consciousness.
A study shows that common cuttlefish can pass a delayed gratification test similar to children, indicating advanced cognitive abilities and behavioral flexibility, likely evolved due to their ambush hunting strategy, challenging previous assumptions about invertebrate intelligence and emphasizing the importance of conservation efforts.
A new study shows that semi-captive elephants use 38 different gestures intentionally to communicate with humans, suggesting they have goal-directed communication skills similar to primates, which may help them navigate complex social lives and offers insights into animal cognition and evolution.
A recent study shows that octopuses, like humans, can be tricked by the rubber hand illusion, suggesting they possess a form of body awareness and self-modeling despite their vastly different neural architecture, challenging assumptions about consciousness in animals.
Many animal species, including birds, insects, mammals, and reptiles, can discriminate quantities and perform basic numerical tasks, often using an innate approximate number system (ANS). While some animals like parrots and chimpanzees can approach true counting, most are limited to quick comparisons and simple estimations rather than complex arithmetic. The ability to do actual math, involving symbols and operations like addition and subtraction, appears to be rare and mostly observed in trained animals.
Scientists are studying the complex calls of mountain chickadees to understand how these social birds use vocalizations to convey detailed information, including food sources and social status, with their calls following systematic rules similar to grammar in human language.
Researchers at the University of Richmond have trained rats to drive tiny cars, discovering that the rodents not only learn to drive but also enjoy the experience. This experiment, led by neuroscientist Kelly Lambert, provides insights into animal cognition and stress, showing that the anticipation and process of driving can be as rewarding as the outcome. The study suggests that such activities may enhance cognitive functions in rats, offering a lesson for humans about savoring the journey rather than just the destination.
A new study by researchers at the University of Tübingen has found that crows can count up to four and match the number of calls they make when shown a numeral. This discovery, published in the journal Science, highlights the advanced numerical thinking and planning abilities of crows, challenging the notion that animals are merely stimulus-response machines. The findings add to the growing body of evidence on crow intelligence and their ability to understand abstract numbers.
A group of top researchers on animal cognition have published "The New York Declaration on Animal Consciousness," stating that there is strong scientific support for conscious experience in birds and mammals, and a realistic possibility of consciousness for all vertebrates, including reptiles, amphibians, fish, insects, and crustaceans. Recent findings have shown evidence of conscious thought or experience in a surprising range of creatures, prompting a shift in how scientists and society view and care for animals. This changing understanding of animal sentience could have implications for U.S. law and animal welfare.
