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. 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.Heh, maybe an Aussie made it?
In this map, are we looking at the same thing?
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.
After a few moments analysis it looks accurate. The important thing we've learned from sex chromosomal analysis (IMO) are accurately reflected, which is: A) Increased to decreased genetic diversity due to genetic bottlenecks with each successive continental migration (i.e., Africa -> Eurasia -> Australia -> North America -> South America)
