Some animals, such as California sea lions, have small brains relative to their body size, but are still impressively intelligent, showing brain evolution is even more complex than it appears.

You share the same drug habits, the same age-related memory problems and are similarly impatient when forced to wait for food.

A marine version of the Stanford marshmallow experiment helped show cuttlefish can delay gratification.
The pigs used a joystick to move a cursor for rewards.
A new study found some dogs learn the name of a new object after hearing it only four times.
For the past 50 years, international animal cognition research has focused on how tool use is related to animal intelligence. But new research casts doubt on long-held assumptions.
Kea were able to correctly guess the most probable scenarios, by evaluating various physical and social cues. Previously, only great apes and humans were known to be able to understand probability.
More than 620 million years of evolution separate crows from humans, but the birds show that they can plan three steps ahead.
New Caledonian crows are famous for using tools to reach a reward. Now scientists have confirmed they can plan several steps ahead, like a chess player contemplating a series of moves.
New research provides early evidence of general intelligence in animals.

Species that use tools aren’t necessarily better at solving problems than species that don’t.
Love me, love my goat.
We assume that dogs are smarter than other domesticated animals, but science says otherwise.
Honey badger: brighter than it looks.
Yes, apes and dolphins are bright. But what about the other animal Einsteins?

The idea of non-human consciousness raises a host of philosophical questions.
The Spangled Drongo is a frequent mimic.
Australian birds are arguably among the smartest in the world, displaying complex behaviours comparable to those observed in great apes.
Can a machine really think, be in awe and wonder?
As machines get ever more complex as we strive to make them complete more complex tasks, it's time to ask again: will they ever be able to think? But what is thinking anyway?
All the better for hearing you with.
Sometimes it may seem like your dog doesn’t want to listen. But in our study, however, we’ve found that he may understand more than he lets on. Human speech is complex, communicating not only words but…
What’s up, bro?
Macaque monkeys grow up with their mothers and are often not familiar with their fathers. But they can recognise the paternal side of the family even without ever being introduced to them, according to…
Are those dried tears?
An elephant that supposedly cried tears when it was being rescued from an abusive home where it had been captive for 50 years created much excitment on social media. The experience of being cut loose from…
Smarter chimpanzees owe much of their extra intelligence to genes.
Not all chimpanzees are created equal. Not only are some more intelligent than others, but about half of this variation is…

Darwin’s finches, a group of 14 species found only in the Galapagos Islands, are perhaps most well known as one of the inspirations for Charles Darwin’s theory of evolution by natural selection. A classic…
