today we're uncovering an extraordinary
0:05
discovery about elephants they use names
0:07
to call each other just like humans do
0:10
scientists at Colorado State University
0:12
have confirmed that wild African
0:14
elephants use namik calls to address
0:16
each other this groundbreaking study
0:19
published in nature ecology in evolution
0:21
reveals a rare ability among non-human
0:24
animals researchers from CSU save the
0:28
elephants and elephant voices used
0:30
machine learning to analyze elephant
0:32
calls they found that these calls
0:34
contain specific components identifying
0:38
recipient when researchers played back
0:40
recorded calls elephants responded
0:42
affirmatively to their names by calling
0:44
back or approaching the speaker calls
0:47
meant for other elephants received less
0:50
reaction unlike dolphins and parrots
0:53
which imitate the signature calls of
0:55
their peers elephants use arbitrary
0:57
vocal labels similar to human names
1:00
this ability to use sounds that
1:02
represent ideas without imitation
1:04
greatly enhances their communication
1:06
skills elephants like humans live in
1:11
structures their communication involves
1:13
vocalizations that convey identity age
1:16
sex emotional state and more they use a
1:20
broad frequency spectrum including
1:22
infrasonic sounds to coordinate group
1:26
distances the study captured 47 distinct
1:30
calls from 101 unique
1:32
callers the researchers used a novel
1:35
signal processing technique and machine
1:37
learning to identify which elephant a
1:39
call was addressed to based on its
1:42
features when researchers played back
1:44
recordings elephants energetically
1:46
responded to calls from their friends
1:48
and family members but ignored calls
1:50
meant for others this demonstrates that
1:53
elephants recognize and respond to their
1:55
names these insights into elephant
1:58
communication strengthen the case for
2:01
conservation elephants are in danger due
2:03
to poaching and habitat
2:05
loss understanding their communication
2:07
could be crucial in protecting them and
2:09
managing human elephant
