A study of DNA extracted from wolf and dog fossils suggests that ancient wolf populations in Europe are the direct ancestors of most modern-day domestic dogs. The study suggests wolves became dogs between 18,800 and 32,100 years ago, before the start of agriculture.
In the northern Rockies of Montana, wildlife is a part of daily conversation. Fishing alone generates $250 million a year, and the pursuit of trout brings in most of that money. But record droughts and declining snowpack mean streams are becoming less habitable for this revered fish.
There's a curious twist in the contentious debate over feeding antibiotics to animals in order to make them grow faster. Evidence suggests using antibiotics for growth promotion, at least among pigs, doesn't even make economic sense. But some pork producers don't believe it.
Humans and other primates have really good vision. One scientist thinks that ability evolved in part to help monkeys and humans quickly recognize venomous snakes. When monkeys see photos of snakes, neurons in a specific part of the brain light up. The neurons respond to photos of the reptiles more than to monkey faces.
It's a happy ending for Neil the potbelly pig, who faced eviction from his California home. Pigs are allowed as pets in Sierra Madre, but not hogs. An animal control officer suspected Neil was a hog — that is, a pig weighing more than 120 pounds. But a protest rally turned into a party when Neil was designated a legal pig by the city.
For most of us, plague is something that maybe we read about in history books. In the 14th Century, it wiped out half of Europe's population. But the bacteria is busy killing wildlife now in the American West. By studying small mammals scientists have learned that plague is far more pervasive a killer than anyone thought.
Diplomats are again meeting to consider setting aside a protected zone in the pristine waters around Antarctica, though their previous negotiations ended in failure. A scaled-back plan on the table this week would still create the largest marine preserve in the world.
We all know why the chicken crossed the road. Now, a new product wants to make sure they get to the other side safely. As chickens become more popular as pets, the British company Omlet is selling high-visibility chicken jackets — tiny fluorescent safety vets for when they're on the streets.
Over the last 20 years, the number of sheep in the U.S. has been cut in half. Today, the domestic sheep herd is one-tenth the size it was during World War II. Consumers are eating less lamb and wearing less wool these days. Those trends have left ranchers to wonder: When are we going to hit bottom?
You may not find South Sudan at the top of most dream destination lists, but the authors of a new travel guide say the young country, long isolated by a violent civil war, has much to offer tourists in search of wildlife, culture and natural beauty.
