I did a quick google and wikipedia search to validate that there was evidence for this.
I don't think we should be surprise, really. We have
Homo floriensis on the small end and your
Homo erectus palaeojavanicus on the other. There were also size differences between other species ...
robustus and [/i]gracile[/i] Australopithicines.
We are also aware of instances of gigantisism and dwarfism in other species ... the "
Pygmy Mammoth" (Channel Islands) comes to mind (in part because it is an oxymoron)
There are also factors know to exist when these extreme diversions evolve, and it would be interesting to see if that also applies here. (
floriensis was an island species it seems)
