New fossil discoveries are reshaping scientists' understanding of a pivotal chapter in human evolution, revealing that several human ancestor lineages lived side by side nearly 3 million years ago.

She walks through the door. You already know this story. But here's what you don't: the femme fatale isn't a Hollywood invention — and she was never warning you about her. Heliox explores anthropologist William Jankowiak's landmark cross-cultural study of dangerous-woman folklore across 84 global societies, from the Igbo of West Nigeria to Aboriginal Australia to modern South Korean farms. The finding that changes everything? In 89% of those cultures, the man wasn't destroyed because he wanted a fling. He wanted to fall in love.

An international team of researchers has discovered 13 fossil teeth in Ethiopia's Afar region that do not fit any known human species. The find suggests that multiple hominid lineages coexisted in Africa more than two million years ago, including one that science had not yet identified.

Human brains have been shrinking since prehistoric times, some studies suggest. Whether this is true and why it has happened are debated.

A recent study published in the journal Social Sciences has found that stories about dangerous, attractive women are almost universal across different cultures. These cautionary tales suggest that men tend to fear the risks of emotional attachment and heartbreak just as much as they are drawn to physical beauty. Ultimately, this research indicates that the famous “femme fatale” character stems from human evolutionary psychology rather than simply local cultural attitudes.

Join us for a conversation about decolonizing research, rethinking education, and building institutions that actually serve the communities at their center. Chris sits down with Dr. Alyssa Crittenden, who returns to the show, this time as Vice Provost for Graduate Education and Dean of the Graduate College at UNLV.

The standard in the US is for the placenta to be treated as medical waste, but cultures across the world have had widely varied traditions, often tied to the belief that the placenta is a living relative or guardian to the child. In an analysis of 179 societies, medical anthropologists at the University of Nevada, Las Vegas, found 169 disposal methods, including burial, incineration, and intentional placement in a specific location, such as hanging in a tree.

Dr. Brian Villmoare of the University of Nevada – Las Vegas shares how his team found teeth in Ethiopia and what those teeth might mean in terms of who was around when in the evolutionary record.

The 2nd annual Missing in Nevada Day is set to run from 10 a.m. to 4 p.m. on Jan. 31 at UNLV's University Gateway Building.

A study on Ozempic’s impacts on Alzheimer’s disease didn’t have the results scientists hoped for. We talk to UNLV’s Dr. Jeffrey Cummings on the research and what’s next. Also from UNLV: a look at how a “new” species of an ancient human ancestor can help shape our view on evolution. We end with a fun story on “Silver Belle”... the first tree from Nevada to serve as the U.S. Capitol Christmas Tree!

Kissing, for all popularity, is a bit of a mystery. Scientists have long debated when humans’ ancestors first put their lips together, and whether the act is simply a cultural trait. A new study suggests giving someone a peck has a long history, dating up to around 21 million years ago, long before modern humans existed. The work was published in the journal Evolution and Human Behavior on November 19.
