An isolated population seed, yes. But a sub-population that can be re-seeded by the main one, no. Homo Erectus has been discovered as far as SE Asia 1 or 2 mill

An isolated population seed, yes. But a sub-population that can be re-seeded by the main one, no. Homo Erectus has been discovered as far as SE Asia 1 or 2 million years ago.
Also typically a population grows depending on birth-death rates which reach quick limits in places of low resources. This is self-evident from different population sizes in different geographic habitats. Instead human populations mushroomed only in select places. See Guns, Germs and Steel by Diamond for more.
- BurningFrog 10y agoSure, but an unpopulated Australia is hardly a place of low resources. The expansion possibilities would be enormous. Even if your colony is surrounded by impenetrable deserts, I'd think you could always propagate along the coast, living off the ocean. That I'm just some internet guy speculating without any deep knowledge is probably obvious, but let me make it extra clear!
- flukus 10y agoImpenetrable deserts aren't known for their abundance of fresh water. Just having resources available isn't everything either, you have to know how to extract those resources, this is a massive barrier to a primitive (excuse the term) culture landing on an alien continent, separated for millions of years. Living off the ocean is also incredibly dangerous.
