Southwest China. Discovery of animal groups that weren’t supposed to exist yet — millions of years earlier than the timeline said was possible.

Every time paleontology does this it’s a little disorienting. The story of life on Earth keeps getting older, stranger, and more front-loaded than the previous model assumed.

“Lost world” is a press release word but the underlying finding is genuinely significant. The Cambrian explosion might be less of an explosion and more of a long fuse.

For thirty years, China’s economic growth was the closest thing the global economy had to a reliable engine. That engine is sputtering, and the effects are spreading in ways that do not respect trade allegiances.

The proximate causes are well documented: a property sector that has not recovered from the Evergrande collapse, consumer confidence that has not returned to pre-pandemic levels, youth unemployment running above 15%, and deflationary pressure that signals demand weakness rather than price stability. The structural causes run deeper — a demographic cliff, a model of export-led growth that trading partners are increasingly resisting, and a domestic consumption base that the government has tried and failed to cultivate as a replacement driver.
