“Christopher Columbus, as everyone knows, is honored by posterity because he was the last to discover America.”*…
When Columbus landed in 1492, the Americas had been settled for tens of thousands of years. He wasn’t the first person to discover the continent. Rather, as Nick Longrich explains, his discovery was the last of many discoveries…
In all, people found the Americas at least seven different times. For at least six of those, it wasn’t so new after all. The discoverers came by sea and by land, bringing new genes, new languages, new technologies. Some stayed, explored, and built empires. Others went home, and left few hints they’d ever been there…
From last to first, here’s the story of how we arrived in the “New World”: “Seven times people discovered the Americas – and how they got there,” from @NickLongrich in @ConversationUS.

As we ponder precedent, we might that it was on this date that about 300 Seneca warriors defeated a detachment of the British 80th Regiment of Light Armed Foot in the Battle of Devil’s Hole (near Niagara Gorge in present-day New York state). The action was part of what is known as Pontiac’s War, which had begun earlier that year when a loose confederation of Native Americans dissatisfied with British rule in the Great Lakes region following the French and Indian War moved to reclaim control of the land they had historically occupied.
Warfare on the North American frontier was brutal, and the killing of prisoners, the targeting of civilians, and other atrocities were widespread. In an incident that became well-known and frequently debated, British officers at Fort Pitt attempted to infect besieging Indians with blankets that had been exposed to smallpox. The war ended the following year after peace negotiations; and while the Natives were unable to drive away the British, the uprising prompted the British government to modify the policies that had provoked the conflict.

As Dylan Matthews explains, 80 percent of young Americans still live within 100 miles of where they spent their teenage years…
A new paper by Harvard’s Ben Sprung-Keyser and Nathaniel Hendren, and the Census Bureau’s Sonya Porter, takes an in-depth look at young adults leaving home. The big takeaway is … they do not.
At age 26, the authors find, 30 percent of Americans live in the census tract they lived in at 16. Fifty-eight percent live less than 10 miles away;80 percent live less than 100 miles away; 90 percent live less than 500 miles away. Census tracts are tiny, hyper-local designations, with populations between 1,200 and 8,000 each; mine is only 0.2 square miles in area. The small town where I grew up has three tracts within it. Staying within your tract is an extreme level of residential stasis, but 30 percent of young adults do just that…
As the demographers and sociologists reading this are likely to point out, the finding that people mostly stay put is not new. Indeed, residential mobility inside the US has been cratering for years, and kept falling even during the pandemic, despite narratives about city residents fleeing…

As we get moving, we might recall that it was on this date in 1610 that explorer and navigator, Henry Hudson and his crew sailed into (what we now know as) Hudson Bay in (what we now know as) Canada. While Hudson is rightly remembered for this and his other explorations and chartings of the northern reaches of North America, it was at the time a disappointment: Hudson initially believed that he had finally found the Northwest Passage through the continent. Months of further exploration and mapping, of course, proven him wrong.

Homo sapiens finger bone, dating back some 86,000 years, found at a site called Al Wusta in Saudi Arabia
Darwin turns out to right about the difficulty of dating the emergence of man, not only for the reason he intended (that our emergence from prior species was so gradual as to be indetectable as an “event”) but also because it’s turning out to be difficult to date the earliest examples we can agree are “man” and to figure out when they reached the places they settled…
The Nefud Desert is a desolate area of orange and yellow sand dunes. It covers approximately 25,000 square miles of the Arabian Peninsula. But tens of thousands of years ago, this area was a lush land of lakes, with a climate that may have been kinder to human life.
On a January afternoon in 2016, an international team of archaeologists and paleontologists was studying the surface of one ancient lake bed at a site called Al Wusta in the Nefud’s landscape of sand and gravel. Their eyes were peeled for fossils, bits of stone tools, and any other signs that might remain from the region’s once-verdant past.
Suddenly, Iyad Zalmout, a paleontologist working for the Saudi Geological Survey, spotted what looked like a bone. With small picks and brushes, he and his colleagues removed the find from the ground.
“We knew it [was] important,” Zalmout recalled in an email. It was the first direct evidence of any large primate or hominid life in the area. In 2018, lab tests revealed that this specimen was a finger bone from an anatomically modern human who would have lived at least 86,000 years ago.
Prior to this Al Wusta discovery, evidence in the form of stone tools had suggested some human presence in the Nefud between 55,000 and 125,000 years ago. To anthropologists, “human” and “hominin” can mean any of a number of species closely related to our own. The finger bone was the oldest Homo sapiens find in the region.
The bone’s dating contradicts a well-established narrative in the scientific community. Findings, particularly from the area of modern-day Israel, Jordan, and Lebanon, known as the Levant region, have led to the understanding that H. sapiens first made their way out of Africa no earlier than 120,000 years ago, likely migrating north along the Mediterranean coast. These people settled in the Levant and their descendants—or those from a subsequent early human migration out of Africa—traveled into Europe tens of thousands of years later.
Only later, that story goes, did they journey into parts of Asia, such as Saudi Arabia. By some estimates, then, anatomically modern humans would not have been in what is now Al Wusta until about 50,000 years ago.
The fingerbone, then, adds a twist to the tale of how and when our species left the African continent and, with many starts and stops, populated much of the rest of the earth. A new crop of discoveries, particularly from Asia, suggest that modern humans first left Africa some 200,000 years ago, taking multiple different routes…
Politics, geography, and tradition have long focused archaeological attention on the evolution of Homo sapiens in Europe and Africa. Now, new research is challenging old ideas by showing that early human migrations unfolded across Asia far earlier than previously known: “Will Asia Rewrite Human History?”

As we return to roots, we might spare a thought for Jean-Léon-François Tricart; he died on this date in 2003. A physical geographer and climatic geomorphologist known for his extensive regional studies in numerous countries of Africa.
Tricart was a pioneer in many fields of physical geography including the study of a phenomenon central to the migration of early Homo Sapiens, the major dynamic role of climate in landscape evolution.
“I long, as does every human being, to be at home wherever I find myself”*…
So … what if everyone went back where they came from?
The always-illuminating Nathan Yau, of Flowing Data, demonstrates that in the U.S., almost everyone comes from somewhere else. See his explanation at “If We All Left to ‘Go Back Where We Came From’.”

As we contemplate commonality, we might recall that it was on this date in 1648 that Mehmed IV became Sultan of the Ottoman Empire… at the age of 6 (as a result of his father’s overthrow). He went on to become the second longest reigning sultan in Ottoman history (after Suleiman the Magnificent). Under his reign the empire reached the height of its territorial expansion in Europe.

Mobility in the United States has fallen to record lows. In 1985, nearly 20 percent of Americans had changed their residence within the preceding 12 months, but by 2018, fewer than ten percent had. That’s the lowest level since 1948, when the Census Bureau first started tracking mobility.
The decline in Americans’ mobility has been staggering… Mobility rates have fallen for nearly every group, across age, gender, income, homeownership status, and marital status.
Declining mobility contributes to a host of economic and social issues: less economic dynamism, lower rates of innovation, and lower productivity. By locking people into place, it exacerbates inequality by limiting the economic opportunities for workers.
A wide range of explanations have been offered to account for these substantial declines in mobility. Many consider the culprit to be the economic crisis, which locked people into declining-value homes; others attribute it to the huge differential in the housing prices in expensive cities. Some economists contend that job opportunities have become similar across places, meaning people are less likely to move for work; others see rising student debt as a key factor that has kept young Americans in their parents’ basements.
Now, a new study from the Federal Reserve Bank of New York suggests that other, more emotional and psychological factors may be at work…
Powerful psychological factors connect people to places, and often mean more to them than money: “Why Some Americans Won’t Move, Even for a Higher Salary.”
[This is an issue that is likely to become more acute as climate change forces millions of Americans to “retreat” to safer and/or more arable ground.]

As we contemplate change, we might recall that it was on this date in 1939 that a German the St. Louis, a German transatlantic liner, was forced to sail back to Europe after more than 900 of its passengers (primarily German-Jewish refugees) were refused entry by Cuba; over 200 of these refugees would later die in the Holocaust.
The St. Louis departed Germany for Cuba on May 13. The majority of the 937 passengers were German Jews fleeing the increasing discrimination and violence against Jews under Hitler, and many planned to stay in Cuba only until they received U.S. visas. However, unbeknownst to most of the passengers, a week before the ship sailed, the Cuban government invalidated one of the types of travel documents held by the refugees.
When the ship arrived in Cuba on May 27, fewer than 30 passengers—those who had the proper papers—were allowed to disembark. Despite days of negotiations, the Cuban government could not be persuaded to allow the refugees to enter. Leaving Cuban waters on June 2, the ship sailed near the Florida coast. Passengers petitioned President Roosevelt for refuge but received no answer. The St. Louis was finally forced to return to Europe on June 6.
