​​7 wisest animals on the Earth​

There are some animals across the globe that are intelligent to such an extent that they match up to human cognition in various aspects including problem-solving and tool use. Apart from that these smart beings also have complex social structures and emotional depth in upbringing their offspring and finding mates. Through these features, they display the various signs of intelligence in the natural world. Here are 7 of the wisest animals on Earth.

African Grey Parrots are among the most intelligent bird species, known for their amazing ability to copy human speech and understand context. They can identify objects, understand concepts like colours and shapes, and even count. Some African Greys have shown the ability to use words to form simple sentences, which tell about their level of comprehension and communication skills that match up to those of young children.

Orangutans are highly intelligent primates that have the ability to use tools and solve difficult problems. They construct beautiful sleeping nests in trees using branches and leaves. They can learn sign language and use symbols to communicate, that represents their advanced cognitive abilities. Their solitary nature does not hinder their intelligence; instead, it shows their adaptability and problem-solving skills.

Crows are well known for their problem-solving abilities and use of tools. They can develop tools from twigs and leaves to extract food from hard-to-reach places. Studies have shown that crows can plan for future needs, a cognitive skill that was once thought to be uniquely human. Their social structures are complex, and they can recognise individual humans and remember faces, which tells that they have advanced memory.

Octopuses are among the most intelligent invertebrates, and are popular for their problem-solving skills and ability to use tools. They can move across mazes, open jars, and escape from enclosures, putting forth advanced learning and memory. Their complex nervous system, with a large brain relative to body size, supports these sophisticated behaviors. Octopuses also show playfulness and curiosity, traits often associated with higher intelligence.

Elephants have large, complex brains and show behaviors that are indicative of high intelligence. They show empathy, mourning rituals, and the ability to use tools. Elephants have been observed cooperating to do some tasks, such as lifting heavy objects together, and they can also recognize themselves in mirrors, which tells that they are self-aware. Their long-term memory is outstanding, and helps them to remember locations of water sources and migratory routes over many years.

Dolphins are well known for their high intelligence, and have traits such as cooperative hunting, complex communication, and problem-solving. They use a variety of voices and body movements to communicate with each other, and some species have been observed using tools. Dolphins also display self-awareness, passing the mirror test, which tells that they can identify themselves in a reflection, which is a more common trait to humans and great apes

Chimpanzees share approximately 98% of their DNA with humans, making them our closest living relatives. Their intelligence is evident in their ability to use tools, communicate through gestures and expressions, and solve complex problems. Studies have shown that chimpanzees can learn to recognize numbers and even understand basic arithmetic. Their social structures are detailed, with established hierarchies and cooperative behaviours that show their advanced cognitive abilities.
