Imagine inviting a few Pilgrims to your Thanksgiving dinner. They would probably be amazed by the delicious food on the table, which is a tastier and larger version of what they once ate. Many of the traditional foods we enjoy during Thanksgiving have been improved over time, thanks to the original inhabitants of the Americas who started cultivating these plants thousands of years ago.
Did you know that Benjamin Franklin wanted the turkey to be America’s national bird instead of the eagle? He believed the turkey was a true native of America. Turkeys were important to many early American cultures. Along with animals like dogs, llamas, alpacas, and guinea pigs, turkeys are among the few animals domesticated in the Americas. Archaeologists have found evidence that about two thousand years ago, some Native American cultures began breeding turkeys in captivity, realizing it was easier than hunting them.
Scientists have learned a lot about these ancient turkeys by studying their droppings, known as coprolites. DNA analysis of turkey coprolites from the American Southwest revealed that a single turkey lineage was maintained in the area for about a thousand years. This shows that Native Americans were breeding and trading turkeys long before Europeans arrived.
Today’s turkeys are quite different from the wild ones that existed during the time of the Pilgrims. The broad-breasted white turkey, commonly found on farms today, has been selectively bred for meat production. These turkeys can convert 2.5 pounds of feed into a pound of meat and reach full size in just five months. Since 1930, the average weight of a turkey has doubled. Farmers achieve this by breeding the largest turkeys, but this has its challenges, as the birds can become so large that natural mating becomes difficult, requiring artificial insemination.
Another fascinating Thanksgiving food is corn, which originated from a wild grass called teosinte in Mexico. Early Americans began farming and breeding teosinte about 9,000 years ago, transforming it into the corn we know today. Research suggests that just a few genetic changes were needed to create corn. Once they had the basic corn template, farmers made gradual changes to develop specific traits.
Similar stories exist for other Thanksgiving foods. For example, a starchy root from Chile evolved into the potato, and bitter squashes became sweet pumpkins. The first people to cross the Bering Strait discovered a nut that eventually led to the creation of the delicious pecan pie.
What connects all these foods is that each breeding process modifies the organism’s genes, whether through traditional methods or modern science. Even “heritage” or “heirloom” varieties are altered versions of wild plants and animals, shaped by human intervention over thousands of years.
Let’s take a moment to appreciate all the people who contributed to making our Thanksgiving meal possible. Stay curious and keep exploring!
Teosinte’s tough seeds evolved to pass through an animal’s digestive system intact, allowing for natural dispersal. While corn looks different today, it still retains this trait.
And remember, it’s never too early to start holiday shopping! Consider a stylish “I Did a Science” t-shirt, now available in ladies’ cut. If that’s not your style, knowledge is always a great gift for any season.
Create a timeline that traces the history of turkeys from their domestication by Native Americans to the modern broad-breasted white turkey. Include key events and changes in turkey breeding. Use drawings, photos, or digital tools to make your timeline visually engaging.
Conduct a simple experiment to understand genetic transformation. Use different colored beads to represent genes and simulate how selective breeding can change the traits of a plant or animal over generations. Discuss how this relates to the transformation of teosinte into corn.
Research the origins of various Thanksgiving foods and create a world map showing where each food originally came from. Use pins or stickers to mark the locations and write a brief description of how each food has evolved over time.
Work in groups to create and perform a short skit or story that illustrates the journey of a specific Thanksgiving food from its ancient origins to the present day. Use props and costumes to make your presentation engaging and informative.
Organize a mini science fair where you and your classmates present projects on the science behind Thanksgiving foods. Topics could include the genetic changes in corn, the domestication of turkeys, or the evolution of potatoes. Use posters, models, and demonstrations to showcase your findings.

If you could bring a few Pilgrims to your Thanksgiving table, they might be surprised by the food, which would be larger, better, and tastier versions of what they ate. Many traditional Thanksgiving foods are enhanced versions of native New World species. Interestingly, before modern genetics and European contact, the original residents of the Americas had already been cultivating these foods for thousands of years, transforming wild plants into delicious staples.
Ben Franklin preferred the turkey over the eagle as America’s national bird, calling it “a true original Native of America.” Turkeys were significant to many early American cultures. Along with dogs, llamas, alpacas, and guinea pigs, turkeys are among the few domesticated animals native to the Americas. Archaeological findings suggest that around two thousand years ago, some Native American cultures realized that breeding birds in captivity was easier than hunting them in the wild.
Fecal analysis, or coprolite studies, can provide valuable information about these animals. When scientists examined DNA from turkey coprolites found in the American Southwest, they discovered that a single lineage of turkey was maintained in the area for about a thousand years. These native cultures were breeding and trading turkeys in a sophisticated manner long before European contact.
Today’s turkeys are quite different from the wild birds that existed during the time of the Pilgrims and Native Americans. The broad-breasted white turkey, commonly found on modern farms, has been selectively bred for meat production. These turkeys can convert 2.5 pounds of feed into a pound of meat and reach full size in just five months. Since 1930, the average weight of a turkey has doubled. Farmers achieve this by breeding the largest and meatiest turkeys, but this practice has its limits, as the birds can become so large that natural mating becomes difficult, necessitating artificial insemination.
Another interesting Thanksgiving food is teosinte, a wild grass from Mexico and the genetic ancestor of corn. Early Americans began farming and breeding teosinte about 9,000 years ago, leading to the development of modern corn, which looks vastly different from its ancestor. Research indicates that just a few genetic changes could have been enough to create corn. Once farmers had the basic corn template, they made gradual changes to develop specific traits.
Similar stories exist for other Thanksgiving foods, such as how a starchy root from Chile evolved into the potato, and how bitter squashes became sweet pumpkins. The first people to cross the Bering Strait discovered a nut that led to the creation of the delicious pecan pie.
What connects all these foods is that each breeding process modifies the organism’s genes, whether through traditional methods or modern science. Even so-called “heritage” or “heirloom” varieties are altered versions of wild plants and animals, shaped by human intervention over thousands of years.

Fun fact about teosinte: its tough seeds evolved to pass through an animal’s digestive system intact, allowing for natural dispersal. Corn may look different, but it retains this trait.
