Are animals smart? – Deron
It’s a fascinating question that intrigues millions of pet owners, animal lovers, veterinarians and scientists all over the world: Just how smart are animals?
Scientists once believed a brain with billions of neurons was a requirement for intelligence. After all, that’s why you’re able to think – neurons are the nerve cells in the brain that connect and transmit messages to each other.
For the record, the human brain has about 86 billion neurons. For comparison, dogs and cats have less than one billion.
Yet the more that scientists like me study animal emotion and cognition – the ability to learn through experiences and thinking – the more we find that humans are not very special at all. Many nonhuman species can do these things too.
Right now, there’s no agreement on how to decide whether a particular animal species is intelligent. But most scientists who study animal cognition have observed that many animals are able to solve problems, use tools, recall important information about their environment and recognize themselves in the mirror.
Toolmaking bears and crows
Memory is a marker of intelligence. Of all animals, humans possess the most accurate and sophisticated memory. But elephants can recognize as many as 30 traveling companions at a time. They also learn to migrate away from drought-prone areas, based on memories of earlier droughts.
That kind of recall – known as episodic memory – is the ability to remember an event, including when and where it occurred. Until recently, scientists thought only humans had it. But now researchers have learned that some birds, cats, rats, monkeys and dolphins have it too.
Animals may not remember every experience – neither do people – but they do recall things critical to their survival. For example, birds know where they stored food. Monkeys know the presence of a predator.
Scientists once thought tool use was an exclusively human ability, but that’s not so. Chimpanzees use sticks to catch termites and stones to crack nuts open. Crows can even manufacture tools. By bending a wire, they can make a hook to retrieve a food reward that’s otherwise out of reach.
Researchers presented eight captive brown bears with this food challenge: Three objects – a large log, a small log and a box – were placed in an outdoor enclosure. A food reward was suspended above them. Six of the eight bears were able to move the logs and box into positions that enabled them to fetch the reward. Essentially, they used the three objects as tools.
Dolphin, chimpanzee communication
Language is another measure of intelligence. People, of course, have enormously sophisticated communication skills. But dolphins have complex dialects in the form of crackles, squeaks and whistles. Many researchers say the noises are a language. Chimpanzees and gorillas have used sign language to express emotions and ask for things from people.
Self-awareness – the ability to recognize yourself as an individual – signals intelligence. Babies don’t recognize themselves in the mirror until they are about a year and a half old. Up until then, they probably think the mirror image they see is another baby.
Many other species, including dolphins, ravens and elephants, recognize themselves in the mirror. Researchers put a red dye mark on chimpanzees under anesthesia; once awake, the chimps saw their reflection in a mirror. Instead of touching the red mark on their reflection in the glass, they touched the red mark on themselves, indicating self-recognition.
Just because animals can’t do certain things, it doesn’t mean they’re unintelligent. After all, humans can’t fly like a bird or swim like a fish. Nor is there a need for us to have the incredible sense of smell a dog has. We’d be sniffing hundreds of different smells from miles away – the scents from perfumes and pollution, gardens and garbage. From an evolutionary standpoint, that wouldn’t help us much. Plus, we’d get sick of it very quickly.
But all animals, including humans, have developed a wide range of capabilities so they can succeed in the environment they live in. Put simply, we’re all using our brains. Now that’s intelligent.

News Brief
Earthquake Swarm Shakes Southern California Near Salton Sea
Earthquake Swarm: A swarm of earthquakes near California’s Salton Sea and Brawley area has prompted increased monitoring by seismologists as hundreds of tremors shake the region.
A swarm of earthquakes has been rattling Southern California near the Salton Sea, drawing attention from residents and seismologists across the region.
Salton Sea earthquake swarm?
The activity is centered near Brawley in Imperial County, an area known for frequent seismic movement due to its location within the Brawley Seismic Zone. According to the U.S. Geological Survey, hundreds of small earthquakes have been recorded over the past several days, with the strongest reaching a magnitude of approximately 4.7.
Residents throughout Imperial Valley, parts of Riverside County, and even portions of Arizona reported feeling shaking from several of the larger quakes. Minor incidents such as falling objects and brief power disruptions were also reported, though no major injuries or widespread structural damage have been confirmed at this time.
The region sits near the southern end of the San Andreas Fault and is considered one of California’s most geologically active areas. Scientists say earthquake swarms are relatively common near the Salton Sea because of the interaction between tectonic fault systems and geothermal activity beneath the surface.
While experts continue to monitor the situation closely, they emphasize that earthquake swarms do not necessarily indicate that a larger earthquake is imminent. However, officials encourage residents to review emergency preparedness plans, secure heavy furniture, and keep emergency supplies ready.
The Salton Sea region has experienced similar seismic swarms in the past, making it an important area of study for earthquake researchers and emergency management agencies.

Frustration at the Pump: Why Americans are Exploring Electric Vehicles
Exploring Electric Vehicles: For more than one-third of Americans, one simple number is leading them to research electric vehicles: the final tally at a recent gas station fill-up. The pump is no longer just the close of a sale; for a growing number of drivers, it’s where questions begin.
Frustration at the Pump: Why Americans are Exploring Electric Vehicles
(Feature Impact) For more than one-third of Americans, one simple number is leading them to research electric vehicles: the final tally at a recent gas station fill-up.
This, according to new research from Hyundai Motor America, isn’t a hypothetical situation. In fact, 23% of respondents reported it’s happened to them more than once. For nearly half of Americans, pulling up to the pump now brings frustration or outright dread.
Many drivers have a number in mind where the math begins shifting, and once the shift happens, it rarely goes away. The pump is no longer just the close of a sale; for a growing number of drivers, it’s where questions begin.
For 23% of those surveyed, $5 per gallon is where they would start considering alternatives to a gas-powered vehicle. While some say they wouldn’t consider alternatives based on gas costs at all, this meaningful share of Americans points toward a specific tipping point.
Some begin by comparing models or brands while others find themselves on an automaker’s website, further along in the process than they initially expected to be. Most don’t act on this impulse right away, but drivers are increasingly caught somewhere between curious and committed – and 46% of those surveyed said they’d be likely to seriously research an EV.
The desire to leave the pump behind, which an EV would allow for, is a deal nearly half of respondents said they would take. However, the transition isn’t frictionless as charging access and range anxiety remain the top concerns for 28% of potential buyers.
While the move toward electric vehicles is often framed as a long-term decision made with spreadsheets and financial planning, for many Americans, it’s beginning somewhere smaller: a routine fuel stop and an eye-opening receipt.
