Evolutionary psychologist Adriano Lameira conducted a study to test two hypotheses regarding the volume of the vocal repertoire in primates. The analysis revealed that the number of animals in a group does not influence the richness of their vocal repertoire.
The analysis covered the vocal repertoires of 77 primate species and showed that their vocal stock depends on several factors: where the species lives predominantly (on land or in trees), its body mass, and the interaction of these two characteristics.
It was established that in arboreal primates, the volume of the vocal repertoire increased proportionally with an increase in their body size. For other species, there was no dependence on body size, but the habitat became the determining factor: a terrestrial lifestyle was associated with a smaller repertoire than expected, while a mixed lifestyle was associated with a larger one.
Previously, according to the social brain hypothesis, it was believed that a species' brain size correlates with its social complexity, i.e., group size. This link has been observed in primates, some cetaceans, birds, and carnivorous mammals. In 2005, scientists demonstrated that in 42 primate species, group size was related to vocal repertoire: the larger the group, the more diverse the sounds the species made. This was explained by the need for more precise communication to maintain complex social bonds, which in turn resembled the process of human speech emergence.
However, modern revisions of many primate species' dictionaries show that the direct link with group size is not always obvious. Furthermore, there are other potential factors influencing the size of the vocal repertoire, such as the animal's physique and its habitat.
Adriano Lameira from Warwick University analyzed the vocal repertoires of 77 primate species, including humans, studying their relationship with group size, brain size, body mass, and type of lifestyle (arboreal, terrestrial, or mixed), taking into account phylogenetic relationships between species.
The study found that neither group size nor brain size was a predictor of vocal repertoire size (p > 0.05). Instead, the habitat played a decisive role. In arboreal species, the habitat interacted with body size: every doubling of body mass increased the repertoire by approximately 28 percent (p = 0.027), whereas this dependence was not observed in terrestrial and mixed species.
Habitat also had an independent effect: the repertoires of species with a mixed lifestyle were 17 percent higher than predicted by a model based only on group size, brain size, and body size. Arboreal species' repertoires exceeded the prediction by 8 percent, while terrestrial ones lagged by 6 percent.
According to Lameira, the data refute the idea that primate vocal diversity is due to social complexity. The main factors appear to be physical parameters—body size and environment. The researcher hypothesized that the emergence of language in humans might have been a consequence of our ancestors' arboreal lifestyle, rather than a result of social structure.
Anthropologists previously noted that chimpanzees in the Issa Valley, living in a mosaic environment where dense forests neighbor open areas, more often move on two limbs, but do so along branches rather than on the ground. This observation led scientists to suggest that the development of bipedalism in the ancestors of modern humans was not directly linked to the transition to a terrestrial lifestyle.
The series 'Uzak Şehir' continues to expand its cast ahead of the highly anticipated third season, officially welcoming actor Onur Ozaydın. According to Turkish entertainment sources, Ozaydın will play Enver, a character expected to bring a significant plot twist by appearing in episode 64.
'Uzak Şehir,' a drama that has become a record-holder on Kanal D, is produced by AyNA Yapım. The series has become one of the most successful television dramas in Turkey since its launch. After concluding the second season with episode 63, filming for the third season is scheduled for late August.
One of the main questions surrounding the new season was the identity of the actor chosen for the role of Enver. Turkish media confirmed that this role goes to Onur Ozaydın, an experienced actor known for his work in projects such as Savaşçı (Warrior), Kardeşlerim, Yargı, and Yasak Elma.
Enver is presented as Ali's first lover, who resumes a relationship with the character played by Sinem Ünsal years after their breakup. According to Turkish entertainment sources, Enver is a stylish restaurant owner living in Budapest. He is characterized as an intuitive, cultured, elegant, confident, and charismatic man whose unexpected return is intended to create emotional tension and introduce new dynamics into Ali's story.
The film crew is also preparing for an international shooting schedule. It is reported that scenes featuring Enver will be filmed in Budapest, Hungary, with local shoots planned between August 16 and 20. These foreign shoots will be another important stage of production for 'Uzak Şehir,' which was primarily shot in the Midyat district of Mardin province, where the story of the fictional Albor family unfolds.
Since its premiere in 2024, 'Uzak Şehir' has consistently ranked among the highest-rated television series in Turkey. The series, based on the Lebanese drama Al Hayba, tells the story of Aliya Albor who returns from Canada to Mardin with her son after her husband's death, encountering the traditions and long-standing conflicts of the powerful Albor family. The emotional bond between Aliya and Cihan Albor, played by Ozan Akbaba, has been one of the defining lines of the drama.
Enver's appearance is set to introduce a new emotional conflict as Aliya's past resurfaces, potentially affecting the balance of the relationship that viewers have followed over the previous two seasons. Although producers have not yet disclosed details of his storyline, the addition of Onur Ozaydın has already generated significant excitement among fans awaiting the series' return.
The powerful sound of the four-cylinder turbo engine broke the silence of the night in the quadrant. The Agent noticed that his new vehicle only had four cylinders, recalling a previous pursuit involving a six-cylinder Porsche 930, a configuration that many enthusiasts idealize.
Despite this, the Agent shows respect for the Italian engineering applied to the engine, crediting Aurelio Lampredi and the team responsible for the chassis tuning and the Viscodrive concept. The Coupe proved excellent navigating the narrow exhaust tunnels. However, the purpose of the trip was not leisure; the Agent urgently needed to reach the hideout of the individuals referred to as 'desert rats' to eliminate them.
After completing this mission, he planned to return the Coupe to Val and look for Charlie and his group, then return to White City to resume his work routine, which would please his father, whose influence he suspected had facilitated the events. While driving, the Agent focused on the road, ignoring internal thoughts.
Elsewhere, on the eighty-eighth floor of White City, Marcus, Director of Lithium Scraps Logistics and Closed-Loop Research, observed the metropolis as a perfect model. Beside him, the Commissioner questioned him about the Division's report for the regional block at six in the morning.
Marcus explained that the central communication had prepared the report, following a unified protocol with other citadels. He highlighted that the new autonomous fleet allowed for expanding the lithium effluent disposal area without disturbing unmapped zones, as the previous method of containment by human patrol was expensive and inefficient.
When asked about the Council press reaction regarding the costs of uniform replacement, Marcus stated that the Closed-Loop narrative was perfect. He declared that they would announce a completely clean and error-free patrol technology, guaranteeing citizens punctual transport and safe streets, without them worrying about synthetic chemistry or clothing logistics.
Marcus then asked the Commissioner about the 404 vehicle. The Commissioner confirmed that the digital key had been returned and the vehicle deregistered since midnight. Furthermore, the dispatch transferring Marcus's son to bureaucratic supervision at Level Three was already signed. Marcus expressed paternal relief, considering that Level Three offered superior safety and standard of living compared to the risk of working with scrap.
Later, at 2:56 AM, a Crown Vic parked in a warehouse was disturbed by Charlie's desperate screams. The young man was kneeling before a giant safe, trying to start a V8 engine that refused to run. The atmosphere was heavy, with smells of mineral oil and sweat. Charlie worked exhausted, knowing he was alone, as Colin and others had already left.
While trying to restart the engine, a static crackle interrupted Charlie's work. Suddenly, the roar of a four-cylinder engine started echoing from a distant exhaust gallery. Driven by instinct, Charlie turned off the holographic camouflage and saw the yellow headlights of a Fiat invade the warehouse. He recognized the Coupe.
The Agent jumped out of the Coupe, grabbed Charlie, and forced him into the vehicle. Charlie resisted, claiming he had spent three years assembling that engine. The Agent, without ceremony, entered the driver's seat, and the Coupe shot away, leaving the Crown Victoria behind.
Upon reaching 03:00 AM, as the Coupe ascended a gravel area, a silent, bluish beam of light appeared in the sky. An interception drone hit the zinc roof of the warehouse, and the explosion of the V8 engine caused the shockwave to hit the Fiat. Charlie froze, watching his three years of work turn into a crater.
Inside the Coupe, Charlie confronted the Agent, asking where he was being taken. The Agent clarified that he was not arresting him, but rather getting him off the drone route. When pressed, Charlie revealed that Colin intended to gather the group in the recess of Hidden Valley, waiting for police activity to decrease to begin the escape.
