Summary

Cacti are famous for their spine-shaped leaves, their water-retaining tissues, their green stems, and especially for being among the most well-adapted organisms on Earth for dry environments. This episode, we’re joined by Dr. Aly Baumgartner to discuss the diversity of cacti, their unique adaptations for an unusual lifestyle, and their mysterious evolutionary past. In the news: Stone Age jewelry, kelp fossils, long-jawed fish, and early trees.
