New research shows ancient chili peppers were likely growing in Southwestern states like New Mexico millions of years earlier than previously thought.
Scientists believe birds - which, unlike people, lack heat receptors and don't wince, or worse - when eating the spicy "berry-like" fruits, and spread their seeds across vast areas.
Now, researchers at the University of Colorado say a previously collected fossil shows they were growing in the Americas as much as 50 million years ago - much earlier than the 15 million years ago previously thought.
Study senior author, Stacey Smith - an associate professor in the Department of Ecology and Evolutionary Biology - said finding a fossil that upends settled facts is unexpected.
"All of these sort of distinctive members of the family made of eggplants, chile peppers, tobacco," said Smith, "all of these were around long, long before humans ever encountered them. So they were sort of hanging out waiting for us."
As of March 2023, "roasting green chile" is now the official scent of New Mexico. Lawmakers approved and the governor signed a bill making it the first state in the country with an official aroma.
It's estimated the Land of Enchantment produced a whopping 53,000 tons of the peppers in 2022.
Researchers say the chile-pepper fossils originally were collected from the Green River Formation in northwestern Colorado. The findings challenge the previous scientific understanding that nightshades originated from South America.
Smith said she's a bit awed and happy she's able to relate how the fossil discovery has transformed her understanding of plant diversification.
"'Oh that's a fossil of that kind of lizard' or 'That's a fossil of this kind of plant,'" said Smith. "So, it just so happens that we are the people who study those kind of plants and we look at that fossil and say, 'Hey, that's a chile pepper' - and we're 100% certain that it's nothing else."
The findings were recently published in New Phytologist, noting the entire nightshade family - including peppers, tomatoes, potatoes and more - is much older and was more widespread than previously documented.

CO2 pipelines are on the increase in the United States, and like all pipelines, they come with risks. Preparing for those risks is a major focus of the Community Benefits Agreement between Nebraska-based Bold Alliance and Tallgrass Energy Solutions.
Tallgrass plans to modify an existing gas pipeline that crosses Nebraska to transport CO2.
Bold Alliance Director Jane Kleeb said her organization stands with communities facing energy infrastructure projects, to help ensure they have what they need and that the company is giving back. She pointed to Satartia, Mississippi's 2020 experience with a massive CO2 pipeline leak as evidence of the importance of first-responder training.
"We have real money in here," she said, "$400,000 initially, and then an additional $200,000 for training and $100,000 for an emergency response system that first responders will get, to equip their mostly-volunteer firefighters."
Not only did the Mississippi first responders lack the training for a CO2 disaster, Kleeb said, but some were unaware the pipeline even existed.
Tallgrass has said it will conduct yearly training for first responders in the 10-county area, and send yearly notices to all landowners along the route. Kleeb said she expects the firefighter training to begin within the next few months.
CO2 is colorless, odorless and displaces oxygen, making it potentially deadly. It can disable internal-combustion engines on vehicles needed for evacuation. Although CO2 pipelines cover more than 5,000 miles in the United States and continue to be built, Kleeb said federal regulations aren't yet in place.
"For folks listening, you may be, like, 'What do you mean they don't have regulations in place?' And that's what we've been saying for the last few years: We need regulations in place," she said. "No pipeline will go into operation in our state until those regulations are finished, and Tallgrass then knows the type of safety valves and other things they have to put in place to be in compliance."
This month, a pipeline rupture in Sulphur, Louisiana, leaked more than 2,600 barrels of CO2 and took two hours to control.
Another provision in the Community Benefits Agreement is annual royalty payments, which Kleeb calls a "significant win" for Nebraska landowners.
"Landowners are now going to be getting 10 cents per metric ton that is sequestered of the carbon," she said. "So, that could be up to $1 million every year that will go back to landowners in the path of this pipeline."
Kleeb said no pipeline companies in the Midwest currently pay landowners a royalty for use of their land.

April has been "Invasive Plant Pest and Disease Awareness Month," but the pests don't know that. The U.S. Department of Agriculture says it's the best time of year for Pennsylvanians to spot invasive species before they can do more damage.
Invasive pests cost the United States about $40 billion a year in damages to trees, plants and crops.
Kathryn Bronsky, national policy manager for USDA's Animal and Plant Health Inspection Service said hungry pests include not only invasive insects but diseases they carry, which people can unknowingly spread.
"Some examples of what to be on the lookout for are Asian longhorn beetle and spongy moths, and other pests that harm trees and natural resources," she said. "And fruit flies, citrus greening, spotted lanternfly and lots of others that can damage crops and agriculture here in the U.S."
Bronsky said spotted lanternfly eggs have not hatched yet, so she urges people to be on the lookout for their egg masses, which resemble small mud smears. She recommends scraping them into plastic bags with sanitizer, or squashing them directly. Either approach will help diminish the invasive spotted lanternfly population.
Invasive pests attack different types of trees, Bronsky said. The tree of heaven is their preferred host, but a wide range of fruit, ornamental and woody trees also are at risk. Bronsky added that climate change and certain weather conditions can magnify the impact of invasive pests.
"We know climate change can increase the level of plant pest infestation and disease infection," she said. "It also allows these pests to produce more generations each year, and extends the suitable habitat for these plant pests so they can spread to new areas that we didn't know they could previously exist."
She added that it's important to note that such items as firewood can carry pests, from spotted lanternflies to spongy moths, that can then be spread through the movement of firewood. She suggests people avoid this by purchasing only heat-treated certified firewood.

A new study raised red flags about respiratory health in Pennsylvania, particularly for those living near oil and gas activity.
The study by GeoHealth said nationwide, oil and gas venting and flaring exacerbate asthma in 73,000 children, including nearly 12,000 in Pennsylvania.
Jackson Zeiler, public health analyst for the Environmental Health Project, said energy developers do flaring and venting on a regular basis to remove excess gas. He explained the study looked at the potential health risks associated with the practice.
"There's adverse birth outcomes, there's cancer outcomes," Zeiler pointed out. "Volatile Organic Compounds are a big part of these emissions, which have a whole host of health effects, including respiratory health issues, different neurological effects like headaches and dizziness for people who are working in those facilities, and people who live really close by."
Zeiler noted flaring also contributes to an increased risk of hospitalizations, emergency room visits, worsening asthma and even premature death. But the energy industry said flaring is needed to minimize pressure at well sites, for testing and other reasons.
The study used satellite images and gas-imaging techniques to visualize emissions. Zeiler added companies are required to report their emissions to regulatory authorities and the data is compiled into a National Emissions Inventory through various sensors.
"They looked at the National Emissions Inventory numbers and compared it to the actual imaging that they looked at," Zeiler emphasized. "They found that the imaging saw way more emissions than was accounted for in the National Emissions Inventory. They're able to conclude that companies are underreporting, essentially, what they're flaring and what they're emitting."
He suggested Pennsylvanians could work with lawmakers on stricter reporting guidelines and transparency requirements for oil and gas operators. He also recommended advocating for greater setback distances between well sites and residential areas to minimize exposure.
