Stuff To Blow Your Mind · From the Vault: The Wallace Line, Part 2 · 22 Sep 2026 podcast

Concerning transition zones, ideally, Wallacea should correspond to its original 1924 description, which incorporated the Philippine Islands bar the Palawan group. voice-verified

Notably, though, a voice-verified

Smaller form, introduced by Darlington in 1957, used frequently from 1998 onwards, in which all of the Philippine Islands are excluded, is entrenched within the recent literature, but this is often without evident justification. voice-verified

It should also be recognized that the reduced, meaning southern, Wallacea area, was effectively defined by Heilprin in 1887, but was then labeled the Austro-Malaysian transition. voice-verified

Yeah. voice-verified

Uh so it's a mess. voice-verified

It's this is one reason why I I've really enjoyed researching for these episodes, but like when I was reading all this stuff for the last episode I was just like uh I can't voice-verified

Well, these modifications absolutely are based on empirical observations. voice-verified

I mean it's not just people kind of jousting around about absolutely nothing. voice-verified

Like there the there are reasons uh voice-verified

based on the the different kinds of fauna that have been observed and the underlying theory about like the geologic causes and so forth. voice-verified

But unfortunately, the the theoretical definition of the Wallace line and Wallacea are kind of a mess. voice-verified

There have been a few details that have persisted, but uh there has not been clear or consistent agreement across time on where to place the boundary. voice-verified

Boundaries, whether it's a line or a zone, what to call those lines and zones, and what exactly they mean. voice-verified

So you might be wondering based on that, like, well, if you know, if we can't agree on what we're talking about, is the idea of a fondal faunal boundary here uh just useless or is it nonsense? voice-verified

I think the answer is no. voice-verified

I mean, for one thing, some of this confusion is historical. voice-verified

Like there have been general trends in how the idea is getting refined over. voice-verified

Over time. voice-verified

So there's nothing wrong with that. voice-verified
