What we know about aurochs, the ancestors of modern cattle

What ancient goat teeth reveal about ancient human-animal relationships

About 4,000 years ago, several goats with terrible teeth managed to outlive their better-teethed brethren. With such intense dental damage, the goats were likely fed higher-quality feed than the more dentally gifted herd members, a dietary shift that would've contributed to the difference in life span. These goat teeth underscore the hard truth that humans may inflict harm on the animals they care about most, regardless of intention.

The wild ancestors of dogs first mingled with humans 15,000 to 30,000 years ago

The invention of cheese likely came from a fruit fly landing in a pail of fermenting milk

The chance encounter around 5,500 years ago laid the groundwork for cultured milk products like yogurt and cheese. Over time, microbes evolved in tandem with goats, sheep, and wheat to give us the wide variety of cheeses that we enjoy today.

Measles evolved from an ancient cattle disease as early as 3,000 years ago

Genetic analysis suggests that the closest modern relative of measles is a livestock virus known as rinderpest, with the viral strains diverging between 2,000 and 3,000 years ago. The timing coincided with the rise of major cities above 250,000 people, offering a novel transmission route for the newly mutated measles virus.

The ancient crops we've forgotten how to grow

Roughly half of all world calories today stem from maize, wheat, and rice. But for most of history, plants were domesticated in highly local places. This video dives into the scientists learning about crops no longer highly in use that once fueled entire civilizations in North America. Some forgotten crops include pitseed goosefoot, maygrass, and sumpweed.

Why cows are loving their new robot caretakers

Autonomous robots are transforming dairy farming by letting cows choose when to be milked or cleaned. Dairy robot manufacturer Lely says this ability to decide reduces a cow's stress and increases milk production. The robot systems are costly, but are marketed as increasing efficiency for dairy farmers. And the cows appear to love them.

Even in recent history, adaptations to the environment drove human evolution

Through genetics, environmental pressures, and cultural influences, humans have evolved to tolerate lactose, develop varying skin pigmentation, and acquire genetic resistance to diseases like bubonic plague. The metabolic and digestive systems of Indigenous peoples have adapted to their diet, which is influenced by the availability of food and water.

Inside the world's largest two-headed calf collection

The Two-Headed Calf MOOseum in San Francisco contains 50 taxidermied cow heads, all of which are paired with another one. They are the result of rare genetic mutations called polycephaly, that is, two-headedness. The museum is run by punk musician Henry Rosenthal, who first became captivated by the rare phenomenon in his 20s. Learn more about the exhibit here.

What is Archaeology?

If you are up-to-date on your Jurassic Park lore, then you likely already know the answer to this question. But for those of us who didn't delve into the world in dinosaurs, it's easy to assume that professionals who study old stuff likely study the remains of what came before us, right? Find out in this article by the Society for American Archaeology.

A brief history of human blood groups

This 56-minute comedy and history podcast journeys through the rise of modern bodybuilding, which took off during the 19th century.

The okapi was once considered a cryptid, or an animal with an unverified existence

Similar to dragons or Bigfoot, the okapi was once believed to be a mythical animal, known colloquially as an "African unicorn." Its confusing features include zebra-like legs on a donkey-esque body with a giraffe-like head. However, this animal is both real and quite cute.

Kangaroos evolved exceptionally thick knee cartilage to absorb shock

There is significant conflict in the medical field regarding chronic arthritis. Some advocate for keeping the joint as active as possible while others argue progressive overuse leads to worsening arthritis. To settle the score, scientists have looked outside the human population, discovering kangaroos rarely suffer from arthritis in their knees.

The 'definitive' history of magic mushrooms

Where did magic mushrooms come from, and how did they get their magical reputation? This article explains the history of the psychedelic fungi from pre-history to now. The earliest concrete evidence of psychedelic mushroom use is 12,000-year-old murals in Northern Australia that portray mushroom iconography. Considering how many species seek out and consume psychoactive substances, such as Siberian reindeer, it's possible human use of these psychedelic mushrooms may predate these murals.

East Asian records of auroras may date back to 10,000 BCE

Ancient texts from Japan, Babylon, and China contain accounts of auroras dating back millennia. Because auroral activity and intensity are driven by periodic ebbs and flows in solar activity, these records allow scientists to identify patterns that may help anticipate particularly dangerous future solar storms.

The bison with mystery origins on California's Santa Catalina Island

Bison roam the 75 square-mile channel island of Santa Catalina about 25 miles south of Los Angeles in the Pacific. It's not clear exactly how they got there, but one theory says 14 of them were dropped off as part of a Hollywood film production. Generally beloved by the locals and vacationers, their numbers ballooned to nearly 600 but dwindled amid resource scarcity. What now? See the state of conservation efforts here.

The origin of the symbiotic relationship between corals and the algae that feed them

An analysis of fossilized reefs from northern Africa and Germany suggests that shallow water corals and photosynthetic algae formed a mutualistic partnership between 419 and 359 million years ago. The discovery was made by analyzing nitrogen-isotope ratios in the fossils, which differ depending on whether algae are present, due to various chemical processes.
