For years, dolphins have been heralded as the smartest animals on Earth, second only to humans—though some would even contest that ranking. Aside from humans, dolphins have the greatest brain-to-body ratio among animal species, including primates.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
The great apes are considered the smartest creatures after humans. Of course, humans are biased in this regard, but the intellectual capacity of the great apes is difficult to deny. After all, we share over 96 percent of the same DNA. Orangutans stand out as being especially gifted in the brains department.
Despite the prevailing belief that humans dominate the animal kingdom when it comes to smarts, we're actually ranked as the third-smartest species on the planet -- at least according to Douglas Adams, author of "Hitchhiker's Guide to the Galaxy." But joking aside, there is something to be said for Douglas' idea, at ...
Are dolphins smarter than humans? Current tests for intelligence indicate that dolphins do not possess the same cognitive abilities as humans and are thus not the "smarter" species. Like humans, dolphins possess the ability to beneficially alter their surroundings, solve problems, and form complex social groups.
They found that different brain regions use different strategies to interact with each other. This combination of complementary information between different sources is known as 'synergy' and may explain why the human brain is smarter than our primate ancestors.
The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.
As a result, not only have humans become the most dominant species on the planet, but they have also become by far its most intelligent, imaginative, adaptable and resourceful species.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
The strongest land animal in the world is the elephant. The typical Asian elephant has 100,000 muscles and tendons arranged along the length of the trunk, enabling it to lift almost 800 pounds. The gorilla, the strongest as well as largest primate on the planet, is at least six times stronger than the average human.
Koalas. Koalas are not only extremely cute, they're smart, too! The marsupials know how to listen to their bodies and can dive into a deep sleep for an average of 22 hours a day. Koalas snack on eucalyptus leaves, which aren't high in nutrients—the abundant rest makes this diet possible.
The chimpanzee and bonobo are humans' closest living relatives. These three species look alike in many ways, both in body and behavior.
Yes, kangaroos are intelligent animals. They display their intelligence by bouncing around on their hind Limbs and keeping their front limbs free so they can smack their opponents in the nose.
For years, dolphins have been heralded as the smartest animals on Earth, second only to humans—though some would even contest that ranking. Aside from humans, dolphins have the greatest brain-to-body ratio among animal species, including primates.
We have much bigger brains relative to body size and in absolute size than other mammals, and have a level of intelligence that other animals don't. There are many advantages to intelligence, such as the ability to plan and cooperate, innovate new techniques and share information about what works.
Scientists have studied both species and their brains to find the answer to this very question. And, scientifically speaking, dogs are likely smarter than cats. The research study looked at the brains of animals in the order Carnivora, a group of mammals containing bears, seals, raccoons as well as cats and dogs.
Horses and Dogs are both intelligent animals, but they have different cognitive strengths. Horses excel in areas like navigational intelligence while dogs do better with social intelligence. Neither animal is smarter than the other, that's just what makes them unique!
1. Border collie. According to The Intelligence of Dogs, which ranks 131 dog breeds in terms of their relative intelligence, the border collie is the smartest dog breed known to man.
Pigs are gentle creatures with surprising intelligence. Studies have found they're smarter than dogs and even 3-year-old children! In the wild, pigs form small groups that typically include a few sows and their piglets.
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
Strength changes
While there is no proof that modern humans have become physically weaker than past generations of humans, inferences from such things as bone robusticity and long bone cortical thickness can be made as a representation of physical strength.
It depends on your definition of predator. Lions, gray wolves and great white sharks have one thing in common: They're top predators. Their diets consist almost entirely of meat, and except in rare instances, these animals have no natural predators — except humans.
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
Chimpanzee: 96 percent identical
By studying the genomes of chimps (which after bonobos are our closest living ancestors), researchers are hoping to understand what makes us uniquely human.
Wild chimpanzees are usually fearful of humans and will keep their distance. However, there have been recorded incidents of chimpanzees attacking and killing people. This usually happens when humans move into and destroy chimpanzee habitats, reducing their access to food.
