Hello, this is Six Minute English from BBC Learning English.
I'm Neil.
And I'm Sam.
In English, there are many expressions which use an adjective to compare humans with animals.
For example, you might say she's as busy as a bee.
As hungry as a horse, but you probably won't hear someone say.
She's as clever as a chimpanzee.
Which is strange because of all the animals, it's our close cousins,
chimpanzees, or chimps for short, who are most like us.
Just like humans, chimps are highly intelligent.
They live in social groups and just like humans, these groups have leaders.
Also, like humans, chimps have a desire for power.
In fact, chimpanzees have their own politics,
which is surprisingly similar to human politics, as will be discovering in this program.
Research shows that the reason chimpanzee behavior so closely resembles human politics is because biologically we are almost identical.
Did you know that a chimp is more like a human than like a gorilla?
So, Sam, my quiz question is this.
Biologically, how close are chimpanzees to humans?
