Tool kits are a long held comfort zone and then there’s dna sequencing is rather recent and modeling off the data can be very very speculative versus isotopic dating of a tool site. Layered assumptions on site mutation drift rates versus stably conserved regions etc…
on the general issue my own take is with the prevailing pacific circulation patterns multiple explorations into North America from the west are simply logical. In past years any stroll along a PNW beach seeing the glass fish net floats carried from Asia would make that sort of obvious imho. Far easier than any land travel. And similar travel along the North Atlantic is almost as easy, hopping from landfall to landfall in a northerly arc. Though that has to be done more deliberately than the drift around the North Pacific.

A good raft, a rain catch system and fishing lines could get you across the Pacific. And a lot of luck.

Japanese coastal fishing boats that have suffered power failures have routinely wound up in North America. Academics might traditionally frightened of the ocean, the people that live there notsomuch.

The Romans calculated that a ship could cover in one day what a man on foot could cover in 23 days. And they had roads.

Similar to the North Atlantic. The Brendan Voyage also highlighted that. Their historical reenactment of the Irish saints voyage as told in the tales pointed out that very little of the route from Ireland to North America was even out of sight of land. Of necessity completely avoiding the eastward moving Guif Stream which many offer as an objection to early European travel to North America by choosing a much more northern track. Which, iirc, takes advantage of a counter current alongside the coastal refuge. Although proximity to land is a double edged sword, ease of navigation, possible food, fresh water etc. but otoh? That’s where you get run aground and pounded into flotsam and mush by a storm.

And they had roads. The period I was looking at was 50,000 to 30,000 years ago. I found some references of rafts but boats that could "cruise" may not have been developed then.

I think that people were a lot better at using boats, a lot earlier than we give them credit for. Look how early people reached Australia or the island of Crete, long before any remnants of boats or boat building that have been found so far. The evidence for those early coastal migrations are underwater now.
