It's a common saying
that elephants never forget, but these magnificent animals are more
than giant walking hard drives. The more we learn about elephants, the more it appears
that their impressive memory is only one aspect
of an incredible intelligence that makes them
some of the most social, creative, and benevolent creatures on Earth. Unlike many proverbs,
the one about elephant memory is scientifically accurate. Elephants know every member
in their herd, able to recognize as many as 30
companions by sight or smell. This is a great help when migrating or encountering
other potentially hostile elephants. They also remember and distinguish
particular cues that signal danger and can recall important locations long
after their last visit. But it's the memories unrelated
to survival that are the most fascinating. Elephants remember
not only their herd companions but other creatures who have made
a strong impression on them. In one case, two circus elephants
that had briefly performed together rejoiced when crossing paths
23 years later. This recognition isn't limited to others
of their species. Elephants have also recognized humans
they've bonded with after decades apart. All of this shows that elephant memory
goes beyond responses to stimuli. Looking inside their heads,
we can see why. The elephant boasts the largest brain
of any land mammal, as well as an impressive
encephalization quotient. This is the size of the brain
relative to what we'd expect for an animal's body size, and the elephant's EQ is nearly as high
as a chimpanzee's. And despite the distant relation, convergent evolution has made it
remarkably similar to the human brain, with as many neurons and synapses and a highly developed hippocampus
and cerebral cortex. It is the hippocampus, strongly associated
with emotion, that aids recollection by encoding important experiences
into long-term memories. The ability to distinguish this importance
makes elephant memory a complex and adaptable faculty
beyond rote memorization. It's what allows elephants who survived
a drought in their youth to recognize its warning signs
in adulthood, which is why clans with older matriarchs
have higher survival rates. Unfortunately, it's also what makes
elephants one of the few non-human animals to suffer from post-traumatic
stress disorder. The cerebral cortex, on the other hand,
enables problem solving, which elephants display
in many creative ways. They also tackle problems cooperatively, sometimes even outwitting the researchers
and manipulating their partners. And they've grasped basic arithmetic,
keeping track of the relative amounts of fruit in two baskets
after multiple changes. The rare combination of memory
and problem solving can explain some of elephants'
most clever behaviors, but it doesn't explain some of the things
we're just beginning to learn about their mental lives. Elephants communicate using everything
from body signals and vocalizations, to infrasound rumbles that can be heard
kilometers away. And their understanding of syntax suggests that
they have their own language and grammar. This sense of language may even go beyond
simple communication. Elephants create art by carefully
choosing and combining different colors and elements. They can also recognize twelve distinct
tones of music and recreate melodies. And yes, there is an elephant band. But perhaps the most amazing thing
about elephants is a capacity even more important
than cleverness: their sense of empathy,
altruism, and justice. Elephants are the only non-human animals
to mourn their dead, performing burial rituals
and returning to visit graves. They have shown concern
for other species, as well. One working elephant refused
to set a log down into a hole where a dog was sleeping, while elephants encountering injured
humans have sometimes stood guard and gently comforted them
with their trunk. On the other hand, elephant attacks
on human villages have usually occurred right after
massive poachings or cullings, suggesting deliberate revenge. When we consider all this evidence, along with the fact that elephants
are one of the few species who can recognize themselves in a mirror, it's hard to escape the conclusion that they are conscious,
intelligent, and emotional beings. Unfortunately, humanity's treatment
of elephants does not reflect this, as they continue to suffer
from habitat destruction in Asia, ivory poaching in Africa,
and mistreatment in captivity worldwide. Given what we now know about elephants and what they continue to teach us
about animal intelligence, it is more important than ever to ensure that what the English poet John Donne
described as "nature's great masterpiece" does not vanish from the world's canvas.
I have to take issue with the title of this post. All animals are conscious. The question is how conscious, and of what, but to claim any animal isn't conscious in the sense of having some sort of internal experience is absurd. Similarly, all animals are sentient beings because sentient = "having sensation / internal experience", i.e. conscious.
What you're looking for is either SAPIENT - that is, capable of complex thought like that of humans - or SOPHONT - self-aware and having the capacity to understand oneself or others. Note that these are not equivalent, as theoretically an artificial general intelligence could be sapient without being sophont - but vice versa is likely impossible.
I don't mean to be a jerk, by the way, but you do need to be careful about wording. It can confuse people.
I genuinely learned something today
Most animals are sentient. The word you mean is likely โsapient.โ
Was their any doubt that elephants are conscious, sentient beings? I mean, it's sort of common sense.
I don't get all this nonsense about whether animals like dogs, monkeys, or elephants feel pain or can think. It feels like such an outdated topic that doesn't even need to be talked about because it's so blatantly obvious.
Uh.. Do some people question wether elephants are conscious or not? I don't get it...
TED is not a credible source of information.
i think there is something to social animals and intelligence.
that being said i think most animals are sentient , just have a pet to realize that, most have pretty robust memories too.
Are you saying my dog isnโt conscious nor sentient? Iโd venture that all vertebrates are conscious and sentient at the very least.
Conscious?
Yeah, if the elephant in the room is awake, you will know it.
