Beringia

The Western Hemisphere. General term for the Americas following their discovery by Europeans, thus setting them in contradistinction to the Old World of Africa, Europe, and Asia.

KB, interesting take on the Beringea Hypothesis.

Still, no mention that animals (& humans) were moving across the landscape in both directions, not just from west to east (unless, of course, there were Paleolithic traffic cops patrolling the area with
one-way traffic signs). :D

I still wonder why animals would be heading north at all during an Ice Age, Cogs. Herbivores need plant life and carnivores follow the herbivores. Since we must have a deep ice age in order for Beringia to be uncovered we still have to deal with the idea of all this plant life growing at the time.

T'is a puzzle.
Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed.

I think that most migrations are never one way. It would seem silly to press on into the unknown during adverse conditions when you can retrace your steps back to a more familiar & possibly less harsh environment... It may just be me, but I think that most people (let's exclude Oceania, ok?) ebbed & flowed across the landscape as conditions warranted. That may be why we find caches of items that are necessary to survival. An early form of insurance maybe?

Excellent article. One more component of the peopling of the Americas puzzle to mull over. Sounds like they believe there was ice blocking the way east or west for a period. I imagine that would isolate some animals as well as the humans. But still some inconsistencies enough to keep the debate about the Beringian Standstill Model just that, a model. A Pacific kelp highway route into the Americas seems best to explain sites like Monte Verde.

" And yes, think boats too! "


I don't think animals could build boats, though. As you say, early humans were predators. Like all other predators they would follow the prey animals. This doesn't happen like the flip of a switch and I can't see animals doing anything other than moving in the direction of the plant life.

And if they had boats, they didn't need Beringia.

Methinks boats came into play at some point. We know seafaring is very ancient. A seaweed diet at Monte Verde. And lots of seaweed in between. And plenty of prey as well, in the form of abundant sea mammals, as well as fish.

http://natural-history.uoregon.edu/rese ... hypothesis

"Today, the Coastal Migration Theory has gone from marginal to mainstream as evidence for early fishing and seafaring has accumulated around the Pacific Rim and the rest of the world. It is now known that Island Southeast Asia, Australia, western Melanesia, and the Ryukyu Islands were settled by seafaring peoples between ~50,000 and 35,000 years ago, and California’s Channel Islands were settled at least 13,000 years ago. The tide also turned with the identification of several types of seaweed at the Monte Verde II site near the coast of Chile, dated to ~14,000 years ago. Recent geological research suggests that the ice-free corridor was still closed at that time, while the coastal route appears to have been open by ~16,000 years ago."

Perhaps they needed to wait until a coastal kelp highway route became open, about 16,000 years ago as suggested....

http://werc.ucsc.edu/Estes/Estes%20Publ ... slarch.pdf


"In this article, a collaborative effort between archaeologists and marine ecologists, we discuss the role kelp forest ecosystems may have played in facilitating the movement of maritime peoples from Asia to the Americas near the end of the Pleistocene. Growing in cool nearshore waters along rocky coastlines, kelp forests offer some of the most productive habitats on earth, with high primary productivity, magnified secondary productivity, and three-dimensional habitat supporting a diverse array of marine organisms. Today, extensive kelp forests are found around the North Pacific from Japan to Baja California. After a break in the tropics—where nearshore mangrove forests and coral reefs are highly productive—kelp forests are also found along the Andean Coast of South America. These Pacific Rim kelp forests support or shelter a wealth of shellfish, fish, marine mammals, seabirds, and seaweeds, resources heavily used historically by coastal peoples. By about 16,000 years ago, the North Pacific Coast offered a linear migration route, essentially unobstructed and entirely at sea level, from northeast Asia into the Americas. Recent reconstructions suggest that rising sea levels early in the postglacial created a highly convoluted and island-rich coast along Beringia’s southern shore, conditions highly favorable to maritime hunter-gatherers. Along with the terrestrial resources available in adjacent landscapes, kelp forests and other nearshore habitats sheltered similar suites of food resources that required minimal adap- tive adjustments for migrating coastal peoples. With reduced wave energy, holdfasts for boats, and productive fishing, these linear kelp forest ecosystems may have provided a kind of “kelp highway” for early maritime peoples colonizing the New World."

(Sounds like boats would not have been feasible much earlier then 16,000 years ago. As well, Beringia sounds like a resource rich area. But, once the way was open to explore to the south of Beringia, that opportunity was met head on. And likely by maritime travel....)
