Fri, 22 Sep 2023 11:08:31 EDT //www.koonmotors.com/releases/2023/09/230922110831.htm //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.

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.

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.

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.

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.

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.

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.

Mon, 15 May 2023 13:20:00 EDT //www.koonmotors.com/releases/2023/05/230515132000.htm //www.koonmotors.com/releases/2023/05/230504094942.htm Similar to humans, chimpanzees combine vocalizations into larger communicatively meaningful structures. UZH researchers suggest that this ability might be evolutionarily more ancient than previously thought.

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'.

They discovered that bonobo populations differ in a key immune trait depending on the presence of malaria infection. Infected populations have a higher frequency of an immune variant that protects against developing severe disease, a pattern that mirrors what is observed among human populations.

The study gets at age-old nature/nurture questions about why adolescents take more risks: because of environment or because of biological predispositions? Mon, 23 Jan 2023 09:25:39 EST //www.koonmotors.com/releases/2023/01/230123092539.htm //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.

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.

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.
