Well, itâs hard for the Astralo-Melanesians to get to Easter-island by the open sea voyaging when they didnât manage to get to Vanuatu before the Austronesians.
It is possible that they didnât really need ships to get to Australia from present-day Indonesia if the climate between two glacial maximums fluctuated enough to cause the sea-level to drop dramatically for a period. From there they could get to Papua by circumventing the Wallace Line.
Letâs remember plenty of mammals and even Homo floresiensis made it to Southeast Asia 25 thousand years before the first ancestor of Astralo-Melanesians reached those islands. The island Flores is also beyond the Wallace line.
I thought itâs been shown that the sea level didnât drop that far, and the migrations to Australia must have been waterborne. Wouldnât Asian animals also have migrated into Australia if the crossing was doable by land?
Perhaps the land bridge was not complete; doable if youâre a tallish human standing on your hind legs, but not if youâre built low to the ground (and donât have the brains to think âI wonder whatâs on the other side of this dangerous-looking bit of quicksand?â).
Assumptions that species before could do something are as factual as those that state they couldnt. Always good to keep a good open mind and dont just assume everyhing other thanu u s were retarded by small brains.and lack of will.
These kinds of science aare fascinating.in the fact how little we all realize we know⌠its afact until we find another skull fragement.
Maybe we should just call it 'animal intelligence '.
I mean anybody who ever owned a dog can tell they are intelligent and able to understand what we are thinking or going to think (hence the guilty look when you walk in the house and you havenât even seen the damage yet ).
For sure. However, humans are pretty clever and curious. Intelligent has yet to be proven based on a species level assesment. That isnt to say we havent dont intelligent things, just that we dont often do intelligent hungs. The arrogance with us humans is whats most instersting to science and how we evolved via not giving a flying phuck
