@Blickers,
I think thats what Set was getting at. Wed have to push back this possible "migration event via a "land bridge" back into H. e. times. Its possible and we are only speculating via similar migrations "out of Africa"
One of the realities of the 130K date is that it just precedes the Sangamonian "interglacial" period which , by its classical definitions via pollen and marine Oxygen isotopes didnt begin until about 125 kybp.
That would mean that the Illinoian glaciation period was just ending but perhaps the seaa levels had not yet risn (the Sngamon ws a real tropical "Climate change" peiod, here Palm trees and tropical pollens ere found in bogs as far north as Massachussets.
You can look up the estaablished time periods that would frame this discovery site
SANGAMONIAN INTERGLACIAL -established based on soil cores from Sangamon County Illinois
MARINE ISOTOPE ZONE 5(e) (Oxygen isotopes show variable ratios of O16/O18 from cores taken in marine sediments) Sort of established the warmth level of the whole continent v the planet
POLLEN ZONE E (4)--bbasd upon soil pollen levels established from cores taken in Amersfoort , Netherlands
The boundaries of these time zones, are pretty well established, so its necessary that the isotope samples collected at the Cerutti site in Calif. be carefully established.
Im not critiquing it Im just letting yall know that theres not just some "arm waving" going on in this science. Incredible standards of QA have to be met
