Hello, this is Six Minute English from BBC Learning English.
I'm Neil.
And I'm Georgina.
How did you spend your free time during the weeks of lockdown, Georgina?
Repainting the living room or doing exercise classes in the kitchen?
Actually, Neil, I've been doing some online research into my family history.
I'm investigating my family tree.
You know, a drawing showing all the relationships between the different members of my family.
Oh, how interesting.
And how appropriate because trees are the subject of this program.
Not family trees, but real living in the forest trees.
Well, Neil, this might surprise you, but according to some people,
trees also have families.
There are mother trees who support and help feed child trees.
That's right.
According to Suzanne Simard, one of the world's leading tree researchers,
trees should be seen as intelligent.
They communicate with each other.
