In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition or subtraction. Now, a study by the University of Barcelona, published in the journal Scientific Reports, reveals that some giraffes are also capable of deciding which of two options contains more food after mentally combining two quantities, a process comparable to simple addition. These results suggest that giraffes possess a cognitive foundation that could support more complex arithmetic skills. https://phys.org/news/2026-06-giraffes-combine-quantities-similarly-addition.html Plants & Animals Mon, 29 Jun 2026 12:00:01 EDT news701951221 Patterns reveal the individual: A novel AI algorithm equips researchers with a powerful new tool to accurately identify individual jaguars, zebras and giraffes in real time based on their unique coat patterns. Biologists and ecologists can now observe individual wild animals as they move from place to place, as well as their behavior and development over long periods, accurately, with much less effort and significantly faster than before—a major step forward for nature conservation. The scientists explain how this works in the journal Methods in Ecology and Evolution. https://phys.org/news/2026-06-ai-tool-wild-animals-unique.html Ecology Tue, 23 Jun 2026 14:20:06 EDT news701436782 For decades, ecologists have theorized that the extinction of one important species could set off a chain reaction of losses throughout an ecosystem. Now, new research offers some of the clearest real-world evidence that this idea of coextinction is not just theoretical. https://phys.org/news/2026-05-elephant-declines-trigger-wider-ecosystem.html Plants & Animals Fri, 29 May 2026 12:40:04 EDT news699269895 Look up at the clouds. What do you see? A sailboat? A seahorse? Your great-aunt Rosemary? As humans, we're prone to seeing patterns where they don't actually exist. This behavior is so common there's a name for it: apophenia. But sometimes, those patterns really do exist.

Through microscopic analysis of bone tissues, the researchers were able to determine that this peculiar animal reached skeletal maturity at three years of age, while reproductive maturity began around the second year. https://phys.org/news/2026-04-ampelomeryx-grew-life-history-giraffe.html Paleontology & Fossils Wed, 29 Apr 2026 13:40:07 EDT news696681781 The south coast of South Africa's Western Cape province is a rich source of fossil tracks and traces—clues suggesting what this environment may have been like many thousands of years ago. https://phys.org/news/2026-04-bird-tortoise-fossil-tracks-south.html Paleontology & Fossils Thu, 16 Apr 2026 16:00:09 EDT news695567462 A team of scientists from EPFL and Alaska Pacific University has developed an AI program that can recognize individual bears in the wild, despite the substantial changes that occur in their appearance over the summer season.

Their closest living relatives are anteaters and armadillos, and if that seems like an odd pairing, there's a reason why. Today, there are only two sloth species, but historically, there were dozens of them, including one with a bottle-nosed snout that ate ants and another that likely resembled the ancestors of modern armadillos. https://phys.org/news/2025-05-scientists-figured-extinct-giant-ground.html Evolution Thu, 22 May 2025 17:04:06 EDT news667152242 By analyzing the arrangement of vertebrae in the spines of nearly 400 species of tetrapods—a group of animals with four limbs, such as mammals, reptiles, and birds—RIKEN researchers have found some follow a predicted pattern, whereas others do not. https://phys.org/news/2025-05-mammal-spines-hox-gene-birds.html Plants & Animals Thu, 01 May 2025 11:10:10 EDT news665316601 What roils beneath Earth's surface may feel a world away, but the activity can help forge land masses that dictate ocean circulation, climate patterns, and even animal activity and evolution.
