I am watching Helix and have heard this term a few times. I have tried googling it only to end up confused as to what it means.

First time hearing it…. but it basically says if you find plants in more places, absent something obviously restricting their spread, that means they’ve been there longer.

More area occupied by the plants = longer time the plants have been present

I understand it as a link between age and area.

If something occupies a larger space, it has likely been around for longer than something similar that is using a smaller space.

Example.
A plant species found over an area of 10 acres has likely been there for longer than a plant species that spans only 2 of the same acres
