Humans often seize their sense of smell for granted, but when compared to the olfactory capabilities of other vertebrates, our noses fall surprisingly short. While You can detect a wide range of scents, many animals possess a sense of smell that is exponentially more powerful, playing a crucial role in their survival, navigation, and social interactions. Understanding where humans rank on the scent spectrum reveals fascinating insights into the evolution of smell and the diverse ways animals experience the world.

The ability to detect odors relies on olfactory receptor neurons located in the nasal cavity. These neurons bind to odor molecules, sending signals to the brain for interpretation. The number of olfactory receptor genes an animal possesses is a key indicator of its potential smelling ability. Humans have approximately 400 functional olfactory receptor genes, a number that seems substantial but is dwarfed by many other species. This difference in genetic makeup directly impacts how effectively an animal can distinguish and identify scents.

The Super-Smellers of the Animal Kingdom

Rodents, for example, boast an extraordinary sense of smell, possessing over 1,000 olfactory receptor genes. This allows them to detect even the faintest traces of predators, locate food sources, and navigate complex environments with remarkable precision. Their reliance on scent is so profound that it shapes their behavior and social structures.

But rodents aren’t alone in their olfactory prowess. Many mammals, including dogs and bears, have a significantly higher number of olfactory receptors than humans. Dogs, famously known for their tracking abilities, possess around 880 million olfactory receptors in their noses, compared to the roughly 6 million found in humans. This difference explains why dogs can detect scents that are completely imperceptible to us, such as explosives, drugs, or even medical conditions like cancer.

Sharks: Masters of Aquatic Scent Detection

Even in the aquatic realm, the sense of smell is paramount. Sharks, often portrayed as fearsome predators, rely heavily on their olfactory systems to locate prey. According to the Natural History Museum, sharks have an incredibly sensitive sense of smell, capable of detecting minute amounts of blood in the water from considerable distances.

Unlike humans who primarily breathe and smell through the same nasal passages, sharks have separate systems. Water flows into a special olfactory chamber, allowing them to detect scents without disrupting their breathing. This specialized adaptation, combined with their large olfactory bulbs, makes them exceptionally adept at scent tracking. Sharks are cartilaginous fish, meaning their skeletons are made of cartilage rather than bone, a characteristic shared with rays and skates.

Human Smell: A Relative Weakness

Compared to these animals, humans are considered to have a relatively poor sense of smell. While we can distinguish thousands of different odors, our olfactory capabilities are limited by our fewer olfactory receptor genes and a reduced olfactory bulb size. This isn’t to say that our sense of smell is unimportant; it plays a vital role in taste, memory, and emotional responses. However, it’s clear that we don’t experience the world through scent in the same way that many other vertebrates do.

Humans and sharks are both vertebrates, but their physical attributes differ significantly. Humans have a skeletal system made up of bones, while sharks have a skeleton made of cartilage.

The Evolutionary Trade-Offs

The relatively weaker sense of smell in humans is thought to be linked to the development of our visual system. As our reliance on vision increased, the importance of smell diminished. This evolutionary trade-off allowed for the development of more complex cognitive abilities and social structures.

Interestingly, even within the human population, there is significant variation in olfactory sensitivity. Some individuals are “supertasters” of smell, possessing a higher density of olfactory receptors and a greater ability to discriminate between odors. This variation highlights the complex interplay between genetics and environmental factors in shaping our sensory experiences.

As research continues, we are gaining a deeper understanding of the intricacies of the olfactory system across different species. This knowledge not only sheds light on the evolution of smell but too has potential applications in areas such as conservation, disease detection, and even the development of new technologies inspired by the remarkable sensory abilities of the animal kingdom.

The 2026 EE BAFTA Film Awards delivered a night of surprises and celebrated cinematic excellence, with Robert Aramayo emerging as the biggest winner. The British actor defied expectations, taking home both the Leading Actor award and the EE Rising Star Award – a first in BAFTA history. Aramayo’s win for his portrayal of Tourette syndrome campaigner John Davidson in the film I Swear marked a significant moment, overshadowing nominations from established stars like Leonardo DiCaprio and Timothée Chalamet. The awards, held at London’s Royal Festival Hall, showcased a diverse range of talent and films, setting the stage for the upcoming awards season.

Aramayo’s double win was met with jubilation, and his acceptance speech reflected his disbelief. “I honestly cannot believe that I have won this award. I really, really cannot. Everyone in this category blows me away,” he said. He also expressed gratitude to fellow nominee Ethan Hawke, recalling a formative talk Hawke gave at Juilliard about longevity in acting and protecting one’s craft. The night also saw first-time BAFTA wins for Jessie Buckley, Wunmi Mosaku, and Sean Penn, alongside a first-time nomination and win for Ryan Coogler and a Best Director win for Paul Thomas Anderson.

Robert Aramayo’s Unexpected Triumph

The biggest shock of the evening, as noted by Variety, was undoubtedly Aramayo’s victory over DiCaprio, and Chalamet. His performance in I Swear, a British indie film, resonated deeply with audiences and critics alike. The film’s sensitive portrayal of Tourette’s syndrome, and Davidson’s own presence at the ceremony, added an emotional layer to the event. Host Alan Cumming addressed the audience twice to acknowledge that Davidson’s tics sometimes include offensive language, requesting understanding and creating a respectful atmosphere.

Aramayo’s journey to this moment has been remarkable. Sky News reports that those who taught Aramayo in Hull were not surprised by his success, recognizing his talent from a young age. His dedication to the role in I Swear, and his ability to authentically portray Davidson’s experiences, clearly resonated with the BAFTA voters.

Key Wins and Recognition

While Aramayo’s win dominated headlines, other films and individuals were also celebrated. Paul Thomas Anderson’s One Battle After Another was the night’s biggest overall winner, taking home six awards, including Best Film and Best Director. Sean Penn won the Supporting Actor award for his role in the same film, and Wunmi Mosaku was recognized as Best Supporting Actress for her performance in Sinners. The film Frankenstein also garnered significant recognition in the craft categories, winning awards for production design, produce-up and hair, and costume design.

The red carpet was a showcase of style, with Jessie Buckley, Paul Mescal, Maura Higgins, and Cillian Murphy among those making a statement, as highlighted by The Irish Times. The event, hosted by Alan Cumming, was praised for its lightheartedness and inclusivity, with Cumming even handing out British snacks to attendees like Chalamet and Jenner.

Backstage Moments and Tourette’s Syndrome Awareness

The BBC reported on six backstage highlights from the awards, including the thoughtful approach taken to accommodate John Davidson’s Tourette’s syndrome. Cumming’s sensitivity in addressing the potential for involuntary language demonstrated a commitment to inclusivity and understanding. This moment underscored the importance of I Swear in raising awareness about the condition and challenging societal perceptions.

The BAFTA Film Awards 2026 have not only celebrated outstanding achievements in filmmaking but have also sparked important conversations about representation and inclusivity. Robert Aramayo’s historic win serves as an inspiration, and the success of films like I Swear demonstrates the power of cinema to shed light on important social issues.

As the awards season continues, the BAFTA winners are poised to make a significant impact on the upcoming Oscar nominations. The momentum generated by these films and performances will undoubtedly be felt in the weeks to come. What will be interesting to watch is how this BAFTA success translates to the Academy Awards and whether Aramayo can continue his winning streak.
