US: Expert on early encounters with ‘prehistoric mammals’

The “Solutrean speculation” is a principle that claims the primary folks to reach in the New World — the Americas — have been from prehistoric Spain. It says they introduced with them a particular approach of constructing stone instruments, which supplied the idea for later Clovis know-how that unfold all through North America. The greatest proponents of the idea right now are Dennis Stanford, an archaeologist of the Smithsonian Institution, and Brace Bradley, his colleague.

They say that the folks of the Solutrean tradition some 21,000 to 17,000 years in the past migrated to North America by boat alongside the pack ice of the North Atlantic Ocean.

Those who assist it level to current archaeological finds at Cactus Hill in Virginia, Meadowcroft Rockshelter in Pennsylvania, and Miles Point in Maryland as proof of a transitional part between Solutrean lithic and Clovis know-how.

Shrouded in controversy and dismissed by many, their analysis was put into observe through the Smithsonian Channel’s documentary, ‘Ice Bridge: The Impossible Journey’.

Here, the early humans’ first encounters with animals in North America was explored, the “terrifying” extent to which the animals would have towered over the Solutreans laid naked.

According to the idea, they landed at Chesapeake Bay, the stretch of watershed that runs round 524 miles from Cooperstown, New York, to Norfolk, Virginia.

The documentary’s narrator famous: “Their first process is to search out stones to make the instruments and weapons on which their survival relies upon.”

The nice cover of icy wilderness would have contained natural world by no means earlier than encountered by the Solutreans.

North America on the time would have been dwelling to “huge prehistoric mammals not like any in Ice Age Europe”.

The narrator continued: “Among them, one of the terrifying predators of all time, the short-faced bear.

“Capable of chasing its prey at 25mph and reaching as much as heights of 13 ft.”

The short-faced bear is assumed to have turn into widespread round 800,000 years in the past, ultimately turning into extinct some 11,000 years in the past.

There are two recognised species: the lesser short-faced bear (Arctodus pristinus) and the large short-faced bear (Arctodus simus).

The latter is taken into account to be one of many largest recognized terrestrial mammalian carnivores that has ever existed.

The Solutreans would additionally have faced-down the quite a few big floor sloths that when roamed the Americas.

Megalonyx jeffersonii was the biggest of the bottom sloths in the household Megalonychidae, reaching the dimensions of an ox when totally grown.

It grew to round 3 metres in size, and will weigh as much as 1,000kg.

Evolving in South America round 35 million years in the past, the large floor sloth ultimately migrated to North America eight million years in the past, preferring to dwell round rivers and lakes.

During the Pleistocene interval, which each the short-faced bear and big floor sloth lived by means of, the world skilled what is named the Great Ice Age.

At this time, throughout its peak, as a lot as 30 % of the Earth’s floor was lined by glaciers, with components of the northern oceans frozen, leaving an surroundings in which solely the hardiest of animals might survive.

In 2018, archaeologists found the fossilised footprints of historical humans at White Sands National Monument in New Mexico.

At the identical web site, the researchers additionally discovered human footprints contained in the footprints of big floor sloths — main scientists to imagine that historical humans as soon as stalked and hunted the animal.

While the Solutrean speculation has been welcomed by some, others declare it’s “scientifically implausible”.

Jennifer Raff, a geneticist, writing for The Guardian in 2018, stated the idea “suggests a European origin for the peoples who made the Clovis instruments, the primary recognised stone software custom in the Americas”.

Having appeared in the documentary, Ms Raff wrote: “In addition to the scientific issues with the Solutrean speculation which I’ll talk about shortly, it’s necessary to notice that it has overt political and cultural implications in denying that Native Americans are the one indigenous peoples of the continents.”

In the wake of the speculation, reviews instructed it had been adopted by white supremacist teams, who interpreted the them to say that the “authentic inhabitants of the Americas” have been “white Europeans”, and the present-day Native Americans are the descendants of “later immigrants” from Asia.

Ms Raff claimed: “Indeed, though this explicit iteration is new, the thought behind the Solutrean speculation is a part of an extended custom of Europeans attempting to insert themselves into American prehistory; justifying colonialism by claiming that Native Americans weren’t able to creating the varied and complex materials tradition of the Americas.”

She stated the scientific proof additionally raised eyebrows: “There’s a critical time hole between when the Solutreans might have crossed the Atlantic through the ice bridge (~20,000 years earlier than current (YBP)) and when Clovis instruments start to indicate up in the archaeological document (~13,000 YBP),” and that, “there isn’t a proof of boat use, or instruments used for making boats at Solutrean websites”, amongst different issues.
