I watched a PBS special with the some apparently sensible theory about
the Clovis points in NA. Estimates of the extent of sea ice during the
relevant ice age show the southern margin running roughly from northern
Iberia to the south of what's now the USA.
There is also archaeological evidence that residents of Iberia along the
sea coast were fishermen and hunters of mammals like seals using boats.
The theory is that further and further hunting/fishing expeditions along
the ice margin eventually led to a complete crossing. Whether an
accident of weather or intentional and whether one group or more, is of
course, unknowable.
It made a lot more sense to me than other ideas, as it makes the
appearance of identical tool technology in both places not mysterious.
