Most dog owners think their dog is the best, smartest dog to ever walk the planet. Of course, they're all correct because it's obviously a tie between every dog that has ever existed. But a new study from Duke's Canine Cognition Lab confirms that dogs are actually a lot smarter than humans initially gave them credit for.

The study spanned five years as PhD student, Hannah Salomons and the rest of the Duke team partnered with a national service dog organization, Canine Companions. They were joined by other organizations to assess the cognitive abilities of puppies from eight weeks to 20 weeks of age. The puppies were tested every two weeks until they hit the age threshold of 20 weeks.

All 100 puppies involved in the study were golden retrievers and golden retriever mixes. The team of scientists set out to discover how dog intelligence was developed. They wanted to know whether abilities were developed in different chunks or if they developed together as general intelligence. The results were fascinating to the team. Salomons tells Duke Today, “There hasn't really been a study of this size at this fine scale of detail done on puppy cognitive development before. It was a big undertaking."

What they found is that dogs have an ability to "read minds"—or anticipate what a command will be. This cooperative communication skill develops remarkably early, much earlier than anticipated by those completing the study. Duke Today writes, "Skills such as understanding simple human gestures emerged early, alongside basic skills like working memory." Turns out that this communication skill is unique to dog puppies. Salomons explains to the school's digital outlet that wolf puppies do not display this level of understanding of cooperative communication with humans at such a young age.

"Molly is exceptionally intelligent. She picks up on everything, and she doesn't forget," Jamie Tan tells WBZ News Boston, an affiliate of CBS, about her one-year-old rescue dog. "She's very emotionally intelligent."

In the news segment, they show how the puppies participated in the study, explaining that the dogs had to find treats with only non-verbal cues.

One puppy fell asleep on the job, still inside the clear tube with a treat right in front of his nose. Being a puppy is hard work, especially when they are essentially expected to read minds to find a piece of kibble.

Salomons explains to WBZ News Boston, "They are really tuned in to our communication, and they are prepared to look to us for information. We tested how they look to humans and make eye contact to maybe make a connection or ask for help."

According to the scientists who conducted the study, there's no need to do anything extra to apply this new information. The puppies in the study that were exposed to hundreds of students and staff on any given day at Duke University displayed the same level of socialization skills as a puppy raised within a family unit.

"You're enough for your dog, and giving them a nice, loving home is going to help them develop really well, and [that] your dog is looking to you for information," Salomons shares with the news outlet.

Throughout her prolific and distinguished career, biologist Lynn Margulis made several groundbreaking contributions to science that we take for granted as common knowledge today. For example, she championed James E. Lovelock’s “Gaia concept,” which posited that the Earth self-regulates to maintain conditions for life.

But by far, her most notable theory was symbiogenesis. While it was first written off as “strange” and “aesthetically pleasing” but “not compelling,” it would ultimately prevail, and completely rewrite how we viewed the origin of life itself.

In the late 1960s, Margulis wrote a paper titled "On the Origin of Mitosing Cells," that was quite avant-garde. In it, she proposed a theory: that life evolved through organisms merging together to become inseparable.

In essence, cooperation is the driver of life, not competition and domination. This directly went against Darwin’s “survival of the fittest” principle that was considered gospel in scientific circles. Margulis’ paper was rejected by fifteen journals before getting accepted into the Journal of Theoretical Biology.

Time would be on Margulis’ side, however. By the late ‘70s and early ‘80s, research proved that the two major building blocks of plants and animals, chloroplasts and mitochondria were at one time independent bacteria. This solidified the fact that on a biological level, connection trumps autonomy for longevity. And now that fact is written in textbooks, with no real story of the adversity it overcame to get there.

While it is customary for most new scientific theories to be met with criticism, especially those that completely shift the current narrative, many have noted that sexism played a key part in Margulis’ initial lack of acceptance. On more than one occasion, she herself had hinted that women were seen as mothers and wives first, and scientists second. She recalled that while married to fellow scientist Carl Sagan that “Carl would finish his sentence, unperturbed” while she was expected to “handle all the duties of a 1950s housewife, from washing dishes to paying the household bills.”

And yet, Margulis would have other ideas that were controversial that had nothing to do with her gender. Most famously, she did not believe that AIDS was caused by HIV, and instead believed it was cause by a syphilis-causing type of bacteria, despite there already being decades of research proving otherwise. That view was seen as an endorsement of AIDS denialism, which undermined prevention and treatment effort. Then later in life, Margulis became a vocal proponent of 9/11 conspiracy theories suggesting government involvement the in Twin Towers attacks.

And yet, perhaps this is one of those “you gotta take the good with the bad” situations. Margulis’ inherent contrarian nature gave us both these unfounded, even harmful stances, in addition to entirely new paradigms that altered our understanding of life itself.
