What an odd projection to choose! Half the map is filled with information, the other half is nearly empty. And the center is arbitrarily put at Sydney. I much prefer the Dymaxion projection with this data:

Perhaps to show the migration across the Bering land bridge uninterrupted? But the Dymaxion map retains that and does do it better than (what looks like) the Robinson projection.

Heh, maybe an Aussie made it?

In this map, are we looking at the same thing?

That could be so! While Greenwich is the default center for maps, it is not uncommon to see maps that are centered around Asia or America if that's where the focus needs to be.

    In this map, are we looking at the same thing?

Not exactly, it's a map of how humans migrated from Africa to the rest of the globe. But the data is the same kind: both (semi-)linear progressions on a global scale, over the continents. The Dymaxion also keeps the surfaces intact, instead of having a large distortion at the poles and at Greenwich in the map in your post.

Ah cool. I had no idea that "Dymaxion" was the name for such a thing, good to know :)

Well, to be technically correct, Dymaxion is the name of the projection. A projection is a representation of the surface of a 3D ball on a 2D plane, which is impossible to do without distortions. Here is a funny overview of different projections. All are wrong, but they are useful if you use them right, which that world map doesn't.

I stand corrected; I appreciate the links!
