Why does Chorioactis geaster only grow in two places in the world?
If you love botany, you might have heard of Chorioactis geaster, an extremely rare mushroom that only grows in certain parts of Texas and Japan. The flower-shaped fungus is the only one of its genus, and are naturally found in only these two faraway places.
Scientists don’t know how these two cultures ended up so far apart, or why the mushroom absolutely refuses to grow anywhere else in the world. Scientists believe that the two cultures split about 19 million years ago, but how it all happened remains a total mystery.
