And so we can see for these various islands, we can see their areas and the proportion that got extinct, and it looks like they're plotted on this scatter plot. Now be very careful when you look at this because look at the two axes. It is the vertical axes is the proportion extinct in 2000, so it's these numbers, but the horizontal axis isn't just a straight-up area. It's the natural log of the area. And why did they do this? Well, notice, when you make the horizontal axis the natural log of the area, it looks like there's a linear relationship. But be clear, it's a linear relationship between the natural log of the area and proportion extinct in 2000.
