Decades-Long Social Memory in Apes: Louise Reunites with Sister After 26 Years

A Johns Hopkins team used infrared eye-tracking with 26 apes across Europe and Japan and found that chimpanzees and bonobos gazed longer at former companions than strangers; one bonobo, Louise, now 46, recognized her sister Loretta after 26 years apart, the longest documented nonhuman social memory, suggesting apes remember bonds for much of their lifespans and that memory relates to positive past relationships, with welfare implications for housing and breeding decisions.

Wyoming Unearths 55-Million-Year-Old Primate Fossils with Evolutionary Surprises

Scientists report the discovery of 55-million-year-old primate fossils in southwestern Wyoming, with unusual features that could reveal greater early primate diversity and offer fresh clues about primate evolution.

Wyoming Fossil Finds Reveal Tiny Primate Tetonius varleyorum and New Primate-Evolution Clues

Paleontologists in southern Wyoming report Tetonius varleyorum, a new omomyid primate about the size of a mouse lemur from ~50 million years ago, based on jaw and tooth fragments found at Smiley Draw’s Tim’s Confession. The site also yielded Arapahovius gazini and Anemorhysis savage, making three omomyid species co-located at an early Eocene locality. Published in the Journal of Human Evolution, the findings expand the Tetonius story beyond the Bighorn Basin and suggest branching evolution (not a single, linear anagenetic path) in early primates, broadening the geographic and macroevolutionary context.

When Primates Befriend Other Species: A New Look at Cross-Species Bonds

A study compiling 427 documented cases of primates interacting with 127 other species across 88 primate species (spanning 1970s–2025) finds that play, grooming, and even adoption occur across species, revealing broad social flexibility with implications for conservation, animal welfare, and public health as human–wildlife contact rises.

Cross-Species Bonds: What Primates’ Friendships Reveal About Pets

Observations like Fortunata, a marmoset raised by capuchins in Brazil, show cross-species caregiving can resemble pet-keeping; a new Primates review catalogs 427 cross-species interactions across 88 primate species and 127 other animals, finding patterns where juveniles play, adults groom, and some bonds persist for weeks or months, challenging strict lines between adoption and abduction and suggesting proto-pet-keeping may have deep evolutionary roots, especially in captivity or human-adjacent environments.

Orphaned macaque Punch celebrates first birthday with 2,500 cards

Punch, a young Japanese macaque abandoned by his mother, was raised at Ichikawa City Zoo with help from an orangutan plushie to aid his grip. After initial rejection from other monkeys, his endearing story and charm drew global attention. On his first birthday, he received about 2,500 cards from around the world, with the messages and a video recounting his early days on display at the zoo.

Congo’s orange-lipped monkey roars onto the scene: a new primate species

Scientists in the Democratic Republic of the Congo have identified a new orange-lipped monkey, Colobus congoensis (Likweli), in Lomami National Park. DNA analysis confirmed it as a distinct species within the Colobus genus; the monkey weighs about 15 pounds, roams in groups up to 20, and is distinguished by an orange facial patch and unique roars. Found in a limited range of about 650 miles, the species is likely endangered due to hunting and deforestation, marking the fifth African monkey discovery in 75 years.

Likweli: Congo’s new rainforest monkey unveiled

Scientists have identified a new monkey species, Colobus congoensis, locally known as Likweli, in the Congolese Lomami rainforest. The elusive primate weighs about 15 pounds, spans roughly four feet from nose to tail, sports a dramatic black coat with a pink/orange mouth, and emits a low roar. Its range covers about 650 square miles, and genetic analysis suggests it diverged from its closest relative around 5 million years ago.

Meet the Likweli: A Brand-New Colobus Monkey from the DRC

Scientists describe Colobus congoensis, nicknamed likweli, as a new monkey species from the Lomami region of the Democratic Republic of the Congo; the small, elusive primate has a limited range and faces threats from habitat loss and hunting, described after years of fieldwork and local-community knowledge.

Ancient Laughs, an Interstellar Visitor, and Weather-Editing Concepts

A roundup of recent science finds: researchers trace laughter back to ape ancestors about 15 million years ago, showing a conserved, recognizable chuckle across great apes; the interstellar comet 3I/ATLAS is identified as the oldest detected object in the solar system, likely formed over 12 billion years ago; a conceptual study proposes “weather jiu-jitsu”—gentle atmospheric nudges to steer extreme weather events—though it remains a proof-of-concept; and an analysis of five decades of top hits reveals a rise in self-focused language in Western lyrics, with East Asian lyrics showing more stability.

Laughs Across Evolution: Humans and Apes Share Similar Giggle Rhythm

Researchers reanalyzed decades-old recordings of ape laughter and compared them to new footage of children's laughs, finding that humans and great apes share similar rhythmic patterns in their giggles, suggesting laughter evolved from a common ancestor about 15 million years ago. While human laughter can be faster and more context-dependent, its core rhythm remains similar to apes, highlighting laughter as a social bonding tool. The study, published in Communications Biology, underscores the need for more cross-species recordings to illuminate what makes human laughter unique.

Laughter's steady rhythm traces the evolution from apes to human speech

A cross-species study of laughter in orangutans, gorillas, bonobos, chimpanzees, and humans finds laughter isochronous across extant great apes, with tempo accelerating and variability increasing over roughly 15 million years of hominid evolution. Tickling-induced laughter is more regular than play, and humans show the most context-sensitive tempo changes, indicating progressive gains in vocal control that likely paved the way for speech and language.

Ape Chuckles Trace the Rhythm of Laughter Through Evolution

A new study of chimpanzees, gorillas and other great apes (including human children) shows laughter across the group shares a regular rhythmic pattern; nonhuman apes tend to fixed tempos, while humans vary tempo and timing with context, suggesting laughter evolved as a flexible social signal across species.

Legs Before Hands: Evolution's Leg-Driven Route to Right-Handedness

A new PLOS Biology study analyzing 2,025 primates across 41 species argues that humans’ near-90% right-handedness arises from the combined effects of rapid brain growth and a long leg-to-arm ratio from sustained bipedalism: with legs freed from locomotion, the hands could specialize in manipulation, and the larger brain provided the cognitive substrate, making humans the extreme outlier among primates.

Two Evolutionary Shifts Forged Humans' Strong Right-Handedness

A Oxford-led study analyzing 2,025 primates suggests humans' extreme right-handedness arose from two key evolutionary milestones—upright walking and brain expansion—that shifted early hominins from mild to strong right-hand bias, with Homo species showing increasing dominance and Homo floresiensis exhibiting weaker bias; the findings support a two-stage process and raise questions about why left-handedness persists and how culture reinforces right-handedness.
