More than two years after the virus emerged in China, we still don’t know how it spread through the human population or which animal or animals harbored the virus before this pivotal event.
Meet Katie Hunt, replacing Ashley Strickland, in this edition of Wonder Theory.
The Black Death was the most devastating plague epidemic in the world. We estimate to have killed half of Europe’s population in just seven years in the Middle Ages.
Historians and archaeologists have tried for centuries to identify the source of this pandemic, and now science has stepped up and provided an answer.
Traces of diseases that sickened our ancestors – including the plague pathogen – can be found hidden in the ancient DNA of human remains.
The life of a mastodon, an elephantine creature that roamed North America 13,000 years ago, has been shed light on a study of its tusks.
For the first few years of his life, he was a mommy’s boy – staying close to home with a female-led herd in what is now central Indiana before venturing out on his own. the juggernaut died at the ripe old age of 34, when the tip of another male behemoth’s tusk pierced the right side of his skull.

We now have the most comprehensive map yet of the Milky Way, our home galaxy, and it shows us some pretty cool things.
Hubble, another space telescope that scans the skies, has discovered an equally intriguing cosmic phenomenon.
The dichotomy of dominant male and docile female animals is among nature’s most persistent gender stereotypes. A new book called “Bitch: On the Female of the Species” debunks this sexist misconception and tells a fuller story about the role of females in nature.
Female creatures are just as promiscuous, competitive, aggressive and dynamic as their male counterparts and play an equal role in driving evolutionary change, according to author Lucy Cooke.
The climate has changed
Unlike most polar bears, which hunt seals on sea ice and wander far, this distinct population has adapted to live in smaller habitat and hunt on the ice of freshwater glaciers.
“If you are concerned about the preservation of the species, then yes, our findings are hopeful,” said Kristin Laidre, a polar research scientist at the University of Washington’s Applied Physics Laboratory. “But I don’t think the glacier habitat will be home to large numbers of polar bears. There just aren’t enough.”
