Colorful primates don't have better color vision, study finds
//www.koonmotors.com/releases/2023/09/230922110831.htm
Primate species with better color vision are not more likely to have red skin or fur coloration, as previously thought.

Human shoulders and elbows first evolved as brakes for climbing apes
//www.koonmotors.com/releases/2023/09/230905202500.htm
Researchers report that the flexible shoulders and elbows that allow us to throw a football or reach a high shelf may have evolved as a natural braking system that let our primate ancestors get out of trees without dying. The researchers used sports-analysis software to compare the climbing movements of chimpanzees and small monkeys called mangabeys. While the animals climb up trees similarly, the researchers found that the shallow, rounded shoulder joints and shortened elbow bones that chimps have -- similar to humans -- allow them to fully extend their arms above their heads when climbing down, holding onto branches like a person going down a ladder to support their greater weight. When early humans left forests for the grassy savanna, these versatile appendages would have been essential for gathering food and using tools for hunting and defense. The findings are among the first to identify the significance of 'downclimbing' in the evolution of apes and early humans.

Bonobos grow similarly to humans
//www.koonmotors.com/releases/2023/08/230824111835.htm
Parents with children in adolescence know this all too well: one minute 'the little ones' are just up to your shoulder, and all of a sudden, they're growing over your head. Until now, it was assumed that such pubertal growth spurt in body length only occurs in humans, but not in other primates. Researchers have now investigated this widespread hypothesis in bonobos (Pan paniscus). The result: Pronounced, human-like growth in the adolescent years also exists in bonobos and presumably also in other monkeys. Thus, humans are less exceptional in this trait than previously thought.

Urban great tits have paler plumage than their forest-living relatives
//www.koonmotors.com/releases/2023/08/230817164027.htm
A new study shows that urban great tits have paler plumage than their countryside counterparts. Since the yellow pigment of the breast feathers of great tits comes from the food they eat, the paler yellow plumage of urban birds indicates that the urban environment affects the entire food chain.

How orangutans respond to novelty in the wild
//www.koonmotors.com/releases/2023/08/230815131832.htm
Humans like to discover. Presented with something we've never seen before, most of us will be compelled to explore and learn more about it. The same can't exactly be said for our closest living relatives--the great apes. Although decades of studies have shown that captive chimpanzees, gorillas, and orangutans will eagerly explore unfamiliar objects in a laboratory, great apes have rarely been observed in these encounters in the wild.

More menu choices: Migrant orangutans learn a lot about food by watching the locals
//www.koonmotors.com/releases/2023/07/230710113816.htm
Migrant male orangutans on Borneo and Sumatra learn about unfamiliar foods in their new home range by 'peering' at experienced locals: intensely observing them at close range. This is what an international research team found out in a long-term study with 152 male animals observed over a period of 30 years. Peering was most frequently seen when locals consumed foods that were rare or hard to process.

Genomes of 233 primate species sequenced
//www.koonmotors.com/releases/2023/06/230602115048.htm
Researchers from 24 countries have analyzed the genomes of 809 individuals from 233 primate species, generating the most complete catalog of genomic information about our closest relatives to date. The project provides new insights into the evolution of primates, including humans, and their diversity. In baboons, for example, hybridization and gene flow between different species occurred in the past and is still ongoing in several regions of their range. This makes baboons a good model for the evolution of early human lineages within and outside Africa. In addition, using a specially designed AI algorithm, the genomic data enable new insights into the genetic causes of human diseases.

Dinosaurs were the first to take the perspectives of others
//www.koonmotors.com/releases/2023/05/230522131341.htm
Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings challenge the idea that mammals were the originators of novel and superior forms of intelligence in the wake of the dinosaur extinction.

Information 'deleted' from the human genome may be what made us human
//www.koonmotors.com/releases/2023/04/230427173438.htm
What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard. The new findings, published April 28 in the journal Science, fill an important gap in what is known about historical changes to the human genome.

Sleight-of-hand magic trick only fools monkeys with opposable thumbs
//www.koonmotors.com/releases/2023/04/230404114216.htm
An illusion involving a hidden thumb confounds capuchin and squirrel monkeys for the same reason it does humans -- it misdirects expected outcomes of actions they can carry out. However, marmosets have five equidistant digits, and were rarely fooled by the magician. The research adds to evidence that animals struggle to predict movements outside of their own 'biomechanical ability'.

Orangutan communication sheds light on human speech origins
//www.koonmotors.com/releases/2022/12/221220112426.htm
Research finds orangutans communicate using a complex repertoire of consonant-like calls, more so than African apes. Previous research has only linked the evolution of human language with the voiced-vowel sounds produced by non-human primates, despite human language being composed of vowel and consonant sounds. Orangutans' tree-dwelling nature means they use their mouth, lips and jaw as a 'fifth hand', unlike ground-dwelling African apes. Their sophisticated use of their mouths, mean orangutans communicate using a rich variety of consonant sounds.

Evidence for intentional communication in female putty-nosed monkeys
//www.koonmotors.com/releases/2022/11/221116133842.htm
Female putty-nosed monkeys deliberately use alarm calls to recruit males to defend the group. This is the conclusion reached by evolutionary biologists after conducting observations in the Republic of the Congo. The females kept up their chirping calls until the male took action to defend the group against the predator. Researchers say that this is the first time that intentional vocalization such as this has been observed in the animal kingdom.

These facets of social cognition have been associated with variations in the oxytocin and vasotocin genes (OT and VT) and their receptors (OTR and VTR).To shed light on the genetic basis of this behavior, scientists carried out a new study comparing the available genomic sequences of these genes between modern humans, non-human primate species (e.g., chimpanzees, bonobos, and macaques) and archaic humans, using all the available genomes of Neanderthals and Denisovans.

Researchers design a method to pinpoint the origin of illegally traded chimpanzees
//www.koonmotors.com/releases/2022/06/220601111742.htm
Researchers have produced the first catalog of genomic diversity for endangered chimpanzees in the wild. The catalog, which includes 828 chimp samples from across their range, offers a detailed reconstruction of chimp population structure and fine-scale patterns of isolation, migration, and connection. The researchers use this information to design a method to link confiscated chimpanzees to their place of origin within about 100 kilometers, with the goal to support efforts to combat the illegal trade of chimpanzees and related products.

Some monkeys might pull a poker face
//www.koonmotors.com/releases/2022/05/220525102943.htm
The human facial action coding system, or FACS, has been developed as a tool for cross-species systematic comparisons of facial muscles to help interpret the resulting facial expressions of the common marmoset. The new CalliFACS detected facial mobility in marmosets similar to other non-human primates.

Human fetuses evolved to slow shoulder growth for easier delivery
//www.koonmotors.com/releases/2022/04/220414110833.htm
The growth of human shoulders slows down just before birth and speeds up thereafter; this alleviates the problem of shoulder dystocia. Computed tomography was used to obtain cross-sectional representations of the clavicle in humans, chimpanzees, and Japanese macaques; the researchers then looked at different shoulder-width to birth-risk correlations between humans and the two other primates.

Chimpanzees show signs of recognition toward skulls of their own species
//www.koonmotors.com/releases/2022/04/220407101110.htm
黑猩猩似乎知道chimpanze头骨时e-like, relating to the phenomenon of pareidolia that is linked to the brain's ability to detect faces. The researchers posit that chimpanzee skulls possess face-like cues, general contours, and the overall eye-nose-teeth arrangement that likely activates a network of brain regions originally evolved to detect and process faces.

Monkeys routinely consume fruit containing alcohol, shedding light on our own taste for booze
//www.koonmotors.com/releases/2022/04/220401141345.htm
Scientists analyzed the ethanol content of fruit eaten by spider monkeys in Panama, and found that the fruit regularly contained alcohol: between 1% and 2%. The researchers also collected urine samples, most of which contained secondary metabolites of ethanol. The results provide further evidence that our primate ancestors preferentially sought out fermented, alcohol-containing fruit likely for its greater nutritional value, and that humans may have inherited this proclivity for ethanol.
