Or they could have been ferried over by dolphins. But they'd need flint-knapping skills whatever their mode of transport, which lends credence to the idea of repeat journeys or the initial establishment of a sizeable settlement.
And how big is the bag that carries flint-knapping skills? How large a boat is needed to carry it?
The quantity of tools seems to imply settlement over a long period, but I am still not convinced that a single pregnant mother would be incapable of starting such a settlement.
I realize that in-breeding is a disadvantage, but I have known cats to quite happily create a colony from a single pregnant mother, why would homo erectus be incapable?
I don't know why it should seem so amazing that people then could make boats, anyway. Dug-outs could be made with flint tools, or rafts with outriggers, or whatever.
Its not that incredible, but it is quite important. The ability to make tools and the complexity of those tools including boats tell us a lot about a species. I think it is simply too early to conclude that they made boats without better evidence than a 25 mile sea crossing.
I wonder, could chimpanzees be taught to make dugouts? Do you think they use logs as rafts to get across large rivers in the wild?
If Australia was reached 40 000 years ago or so, it hardly stretches credibility that homo sapiens could have sailed to Crete 120 000 years ago.
A different species apparently. The people who crossed to Australia would have been no less intelligent than the Aborigines that live there today - who for all I hear are pretty clever.
