Sequoia National Park is largely designated as wilderness. That complicates efforts to protect its iconic trees from worsening wildfires. Also, archaeologists keep finding older and older cave art. Here’s what it could tell us about how humans evolved over time.

Protecting Sequoias From Wildfire Raises Tricky Questions

Sequoia National Park in California is known for its towering, iconic sequoia trees, some of which are thought to be thousands of years old. Severe wildfires fueled by climate change and a long history of fire suppression have put these trees at risk. One solution to this problem is to plant new sequoias. But an interesting debate has sparked between those in favor of this and those against it.

The vast majority of the park is officially considered “wilderness,” a federal designation that describes an area “untrammeled by man.” This concept of “untrammeled” has become more complicated in the age of climate change: Some people argue that it means humans shouldn’t intervene, even when the ecosystem is changing because of human-made climate change.

Guest host Maggie Koerth speaks with Marissa Ortega-Welch, host and producer of the “How Wild” podcast from KALW and NPR. The first episode of this podcast, “Untrammeled,” highlights this debate.

What Newly Discovered Cave Art Tells Us About Human Creativity

In July, researchers discovered the oldest known cave art. It was found in a cave on the Indonesian island of Sulawesi, and it shows three human-like figures and a wild pig. The painting was dated at 51,200 years old—5,000 years older than any other known cave art.

The finding continues a trend of researchers unearthing older and older examples of human-made art, including those found outside of Spain and Southern France, where most cave art discoveries have been made.

Guest host Maggie Koerth is joined by Dr. Isobel Wisher, a postdoctoral researcher with the Evolution of Early Symbolic Behavior project at Aarhus University in Denmark, to discuss how this field of archeology has changed over the years, how new technology is making these ancient cave paintings more accessible to the public, and what they can tell us about the human experience.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
