#AnimalIntelligence

A breakthrough set of studies published in Science in early 2025 shows that advanced intelligence on Earth evolved at least twice—once in mammals and once in birds. This challenges long-held ideas about the origins of cognition and has potential implications for neuroscience, artificial intelligence, and the search for intelligent life beyond humans. The reporting from Quanta Magazine and coverage in Wired help frame the significance of these findings.

Birds such as crows, ravens, cockatoos, and chickadees exhibit planning, tool use, problem‑solving, and impressive memory, despite brains that are very different from those of mammals and often much smaller. These abilities have long offered a window into how evolution crafts complex thinking in diverse neural architectures. For example, tool construction by some crows and the seed-cache memory of chickadees illustrate cognitive feats once believed possible only in larger-brained species.

In a major breakthrough that reshapes our scientific understanding of animal intelligence, a series of studies published in Science in early 2025 confirm that advanced intelligence on Earth evolved independently at least twice—once in mammals and once in birds. This finding, as reported by Quanta Magazine and summarized in Wired (wired.com), challenges longstanding assumptions about the origins of cognition in vertebrates and could hold profound implications for neuroscience, artificial intelligence, and the global search for intelligent life.
