How four British migrations defined America
They came from different places and with different ideas, which still resonate today.
- Early British settlement of the American colonies came in four distinct waves, from different places.
- Puritans, Cavaliers, Quakers, and Borderers had their own ideas of what America should be.
- Some of the cultural fault lines in today's America can be traced back to those differences.

How many Americans are of British descent? It's a surprisingly difficult question to answer. Is that because, in an age of hyphenated identities, the founding one is still the default? Or has that identity become so amalgamated that it is now irrelevant? Perhaps the correct answer is: a bit of both.
In the 1980 Census, 61.3 million Americans (32 percent) self-reported British ancestry; most claimed English descent (26 percent), followed by Scottish (4 percent), and tiny amounts of Welsh (<1 percent) and Northern Irish. In the 2010 Census, that figure had dropped to 37.6 million (14 percent), with just 8 percent reporting English heritage, 3 percent Scottish and 2 percent Scotch-Irish.
The precipitous drop in self-reported British antecedents corresponds in part with the rise of those who identify as (unhyphenated) 'American', up from 12.4 million (5 percent) in the 1990 Census to 20.2 million in 2000 (7 percent) – the largest growth of any ethnic group in the 1990s.
However, back around the year 1700, about 80 percent of the population of what was to become the United States were of English (or Welsh) descent, with about 11 percent of African origin, and the rest being Dutch (4 percent), Scottish (3 percent) and other European. The imprint of the British on early American society was overwhelming, diverse and long-lasting: the regional and cultural differences between the settler groups created distinct regional and cultural identities in America.
That's the argument made by David Fischer, a history professor who in 1989 published a 900-page treatise on early migration to North America called "Albion's Seed." He identified four British 'folkways' that came over to the other side of the Atlantic in the 17th and 18th centuries (see map), each with their own ideas about the liberty they wanted to find there.
From exodus to flight
Map showing the origin and destination of four British 'folkways' that influenced American society.
1. The Exodus (1629-41)
- About 21,000 Puritans, migrating from East Anglia to New England.
- These religious fundamentalists believed in 'ordered liberty': everybody had the right to live by their own rules, and the duty to live according to God's law.
- The Puritans were a major influence on the culture of the Northeastern U.S., especially in terms of business and education.
These religious fundamentalists are the ones who came over on the Mayflower and gave America Thanksgiving and the self-image of being a 'City on a Hill'. Puritan society was gloomy and repressive: 'exceeding the bounds of moderation' was a punishable offense, and even just 'wasting time' got you into trouble.The other side of the coin: life was very well-ordered. There was little income inequality and crime rates were low. Not only was charity towards poor the rule, being uncharitable was, yes, a punishable offense. Domestic abuse was punished severely. Women had a relatively high degree of equality. And government operated via town assemblies in which all could have a say.
2. Cavaliers and their Servants (1642-75)
- Some 45,000 Cavaliers drawn from English nobility and their indentured servants, migrating from the South of England to Virginia and the Lowland South.
- These aristocrats believed in 'hegemonic liberty': dominion over self, and others. In other words: keeping slaves was okay, but domination by others was not.
- The Cavaliers were the foundation of plantation culture in the South.
The Cavaliers came from the losing side of the Civil War in England, which was now led by the Puritan-inspired Oliver Cromwell. Royalist, Anglican, and aristocratic, they brought along with them their indentured servants – more than 75 percent of the total migration – hoping to recreate in Virginia and environs the socially stratified agrarian society they had left behind.
When their servants began dying en masse, they started importing African slaves, laying the groundwork for the race-based slavery system that underpinned the economy of the South until the end of the Civil War.
- Around 23,000 Quakers, migrating from Northern England to the Delaware Valley in Pennsylvania, and later to the Midwest.
- These religious liberals believed in 'reciprocal liberty': granting others the freedoms they wanted for themselves, including the right to vote, to own, to be free, to worship, and to a fair trial.
- Quakers had an important impact on the industrial culture of the Mid-Atlantic and Midwestern regions of the U.S.
Quakers replaced a wide range of social acknowledgements according to rank (bows, nods, grovels) by a single, neutral equivalent: the handshake. Quakerism was perhaps one of the first Christian denominations to become indistinguishable from liberal, secular modernity. On the other hand, they were even more prudish than the Puritans. Doctors had a hard time treating Quakers because they described everything from their necks to their waists as their 'stomachs', and everything below as their 'ankles'.
4. The Flight from Northern Britain (1717-75)
- Some 250,000 'Borderers', migrating from the Anglo-Scottish borderlands and Ulster to the Backcountry of Appalachia.
- These individualists believed in 'natural liberty': freedom to do as one pleases, without interference from society or government.
- Borderers contributed to the rural culture of America's South and the ranch culture of its West.
Inhabiting the border regions between Scotland and England, and between protestant settlers and catholic natives in Ireland, the Borderers were used to violence and lawlessness, and to lives that were nasty, brutish and short.It is no coincidence that they ended up in Appalachia, at that time itself a violent border region. It was the kind of world they knew. Borderers were wary of government, prone to violent family feuds, and not bothered by traditional morality. By one estimate, in the year 1767, 94 percent of all 'backcountry' brides were pregnant on their wedding day. These Borderers were not much beloved by other settler groups in America. One Pennsylvanian writer called them "the scum of two nations". But the Borderers also contributed vigorously to the success of both the American Revolution and America's westward expansion.
'Blue' vs. 'Red'?

It's tempting, and perhaps not entirely unjustified, to see in these four strains of British 'folkways' the antecedents of some of America's current cultural divides. One might for example see Puritans and Quakers as constituting elements of the 'blue' tribe, while Borderers and Cavaliers could be considered the ancestors of the 'red' tribe.
But thinking of America as a "death match between Puritan-Quaker culture and Cavalier-Borderer culture", as one commentator put it, is perhaps a bit too easy. There may be plenty of overlap within either pair, there is also much to distinguish each from the other. And then there are other and subsequent migrations contributing to and complicating the picture.
Nevertheless, a bit of cultural archaeology can be illuminating, if only to see where the bodies are buried.

"You dream about these kinds of moments when you're a kid," said lead paleontologist David Schmidt.
- The triceratops skull was first discovered in 2019, but was excavated over the summer of 2020.
- It was discovered in the South Dakota Badlands, an area where the Triceratops roamed some 66 million years ago.
- Studying dinosaurs helps scientists better understand the evolution of all life on Earth.
David Schmidt, a geology professor at Westminster College, had just arrived in the South Dakota Badlands in summer 2019 with a group of students for a fossil dig when he received a call from the National Forest Service. A nearby rancher had discovered a strange object poking out of the ground. They wanted Schmidt to take a look.
"One of the very first bones that we saw in the rock was this long cylindrical bone," Schmidt told St. Louis Public Radio. "The first thing that came out of our mouths was, 'That kind of looks like the horn of a triceratops.'"
After authorities gave the go-ahead, Schmidt and a small group of students returned this summer and spent nearly every day of June and July excavating the skull.

"We had to be really careful," Schmidt told St. Louis Public Radio. "We couldn't disturb anything at all, because at that point, it was under law enforcement investigation. They were telling us, 'Don't even make footprints,' and I was thinking, 'How are we supposed to do that?'"
Another difficulty was the mammoth size of the skull: about 7 feet long and more than 3,000 pounds. (For context, the largest triceratops skull ever unearthed was about 8.2 feet long.) The skull of Schmidt's dinosaur was likely a Triceratops prorsus, one of two species of triceratops that roamed what's now North America about 66 million years ago.

The triceratops was an herbivore, but it was also a favorite meal of the Tyrannosaurus rex. That probably explains why the Dakotas contain many scattered triceratops bone fragments, and, less commonly, complete bones and skulls. In summer 2019, for example, a separate team on a dig in North Dakota made headlines after unearthing a complete triceratops skull that measured five feet in length.
Michael Kjelland, a biology professor who participated in that excavation, said digging up the dinosaur was like completing a "multi-piece, 3-D jigsaw puzzle" that required "engineering that rivaled SpaceX," he jokingly told the New York Times.
Morrison Formation in Colorado

The Badlands aren't the only spot in North America where paleontologists have found dinosaurs. In the 1870s, Colorado and Wyoming became the first sites of dinosaur discoveries in the U.S., ushering in an era of public fascination with the prehistoric creatures — and a competitive rush to unearth them.
Since, dinosaur bones have been found in 35 states. One of the most fruitful locations for paleontologists has been the Morrison formation, a sequence of Upper Jurassic sedimentary rock that stretches under the Western part of the country. Discovered here were species like Camarasaurus, Diplodocus, Apatosaurus, Stegosaurus, and Allosaurus, to name a few.

As for "Shady" (the nickname of the South Dakota triceratops), Schmidt and his team have safely transported it to the Westminster campus. They hope to raise funds for restoration, and to return to South Dakota in search of more bones that once belonged to the triceratops.
Studying dinosaurs helps scientists gain a more complete understanding of our evolution, illuminating a through-line that extends from "deep time" to present day. For scientists like Schmidt, there's also the simple joy of coming to face-to-face with a lost world.
"You dream about these kinds of moments when you're a kid," Schmidt told St. Louis Public Radio. "You don't ever think that these things will ever happen."
Are "humanized" pigs the future of medical research?
The U.S. Food and Drug Administration requires all new medicines to be tested in animals before use in people. Pigs make better medical research subjects than mice, because they are closer to humans in size, physiology and genetic makeup.
In recent years, our team at Iowa State University has found a way to make pigs an even closer stand-in for humans. We have successfully transferred components of the human immune system into pigs that lack a functional immune system. This breakthrough has the potential to accelerate medical research in many areas, including virus and vaccine research, as well as cancer and stem cell therapeutics.
Existing biomedical models
Severe Combined Immunodeficiency, or SCID, is a genetic condition that causes impaired development of the immune system. People can develop SCID, as dramatized in the 1976 movie “The Boy in the Plastic Bubble." Other animals can develop SCID, too, including mice.
Researchers in the 1980s recognized that SCID mice could be implanted with human immune cells for further study. Such mice are called “humanized" mice and have been optimized over the past 30 years to study many questions relevant to human health.
Mice are the most commonly used animal in biomedical research, but results from mice often do not translate well to human responses, thanks to differences in metabolism, size and divergent cell functions compared with people.
Nonhuman primates are also used for medical research and are certainly closer stand-ins for humans. But using them for this purpose raises numerous ethical considerations. With these concerns in mind, the National Institutes of Health retired most of its chimpanzees from biomedical research in 2013.
Alternative animal models are in demand.
Swine are a viable option for medical research because of their similarities to humans. And with their widespread commercial use, pigs are met with fewer ethical dilemmas than primates. Upwards of 100 million hogs are slaughtered each year for food in the U.S.
In 2012, groups at Iowa State University and Kansas State University, including Jack Dekkers, an expert in animal breeding and genetics, and Raymond Rowland, a specialist in animal diseases, serendipitously discovered a naturally occurring genetic mutation in pigs that caused SCID. We wondered if we could develop these pigs to create a new biomedical model.
Our group has worked for nearly a decade developing and optimizing SCID pigs for applications in biomedical research. In 2018, we achieved a twofold milestone when working with animal physiologist Jason Ross and his lab. Together we developed a more immunocompromised pig than the original SCID pig – and successfully humanized it, by transferring cultured human immune stem cells into the livers of developing piglets.
During early fetal development, immune cells develop within the liver, providing an opportunity to introduce human cells. We inject human immune stem cells into fetal pig livers using ultrasound imaging as a guide. As the pig fetus develops, the injected human immune stem cells begin to differentiate – or change into other kinds of cells – and spread through the pig's body. Once SCID piglets are born, we can detect human immune cells in their blood, liver, spleen and thymus gland. This humanization is what makes them so valuable for testing new medical treatments.
We have found that human ovarian tumors survive and grow in SCID pigs, giving us an opportunity to study ovarian cancer in a new way. Similarly, because human skin survives on SCID pigs, scientists may be able to develop new treatments for skin burns. Other research possibilities are numerous.

Pigs in a bubble
Since our pigs lack essential components of their immune system, they are extremely susceptible to infection and require special housing to help reduce exposure to pathogens.
SCID pigs are raised in bubble biocontainment facilities. Positive pressure rooms, which maintain a higher air pressure than the surrounding environment to keep pathogens out, are coupled with highly filtered air and water. All personnel are required to wear full personal protective equipment. We typically have anywhere from two to 15 SCID pigs and breeding animals at a given time. (Our breeding animals do not have SCID, but they are genetic carriers of the mutation, so their offspring may have SCID.)
As with any animal research, ethical considerations are always front and center. All our protocols are approved by Iowa State University's Institutional Animal Care and Use Committee and are in accordance with The National Institutes of Health's Guide for the Care and Use of Laboratory Animals.
Every day, twice a day, our pigs are checked by expert caretakers who monitor their health status and provide engagement. We have veterinarians on call. If any pigs fall ill, and drug or antibiotic intervention does not improve their condition, the animals are humanely euthanized.
Our goal is to continue optimizing our humanized SCID pigs so they can be more readily available for stem cell therapy testing, as well as research in other areas, including cancer. We hope the development of the SCID pig model will pave the way for advancements in therapeutic testing, with the long-term goal of improving human patient outcomes.

Satellite imagery can help better predict volcanic eruptions by monitoring changes in surface temperature near volcanoes.
- A recent study used data collected by NASA satellites to conduct a statistical analysis of surface temperatures near volcanoes that erupted from 2002 to 2019.
- The results showed that surface temperatures near volcanoes gradually increased in the months and years prior to eruptions.
- The method was able to detect potential eruptions that were not anticipated by other volcano monitoring methods, such as eruptions in Japan in 2014 and Chile in 2015.
How can modern technology help warn us of impending volcanic eruptions?
One promising answer may lie in satellite imagery. In a recent study published in Nature Geoscience, researchers used infrared data collected by NASA satellites to study the conditions near volcanoes in the months and years before they erupted.
The results revealed a pattern: Prior to eruptions, an unusually large amount of heat had been escaping through soil near volcanoes. This diffusion of subterranean heat — which is a byproduct of "large-scale thermal unrest" — could potentially represent a warning sign of future eruptions.

For the study, the researchers conducted a statistical analysis of changes in surface temperature near volcanoes, using data collected over 16.5 years by NASA's Terra and Aqua satellites. The results showed that eruptions tended to occur around the time when surface temperatures near the volcanoes peaked.
Eruptions were preceded by "subtle but significant long-term (years), large-scale (tens of square kilometres) increases in their radiant heat flux (up to ~1 °C in median radiant temperature)," the researchers wrote. After eruptions, surface temperatures reliably decreased, though the cool-down period took longer for bigger eruptions.
"Volcanoes can experience thermal unrest for several years before eruption," the researchers wrote. "This thermal unrest is dominated by a large-scale phenomenon operating over extensive areas of volcanic edifices, can be an early indicator of volcanic reactivation, can increase prior to different types of eruption and can be tracked through a statistical analysis of little-processed (that is, radiance or radiant temperature) satellite-based remote sensing data with high temporal resolution."

Although using satellites to monitor thermal unrest wouldn't enable scientists to make hyper-specific eruption predictions (like predicting the exact day), it could significantly improve prediction efforts. Seismologists and volcanologists currently use a range of techniques to forecast eruptions, including monitoring for gas emissions, ground deformation, and changes to nearby water channels, to name a few.
Still, none of these techniques have proven completely reliable, both because of the science and the practical barriers (e.g. funding) standing in the way of large-scale monitoring. In 2014, for example, Japan's Mount Ontake suddenly erupted, killing 63 people. It was the nation's deadliest eruption in nearly a century.
In the study, the researchers found that surface temperatures near Mount Ontake had been increasing in the two years prior to the eruption. To date, no other monitoring method has detected "well-defined" warning signs for the 2014 disaster, the researchers noted.
The researchers hope satellite-based infrared monitoring techniques, combined with existing methods, can improve prediction efforts for volcanic eruptions. Volcanic eruptions have killed about 2,000 people since 2000.
"Our findings can open new horizons to better constrain magma–hydrothermal interaction processes, especially when integrated with other datasets, allowing us to explore the thermal budget of volcanoes and anticipate eruptions that are very difficult to forecast through other geophysical/geochemical methods."
