Weekly Wildlife: Horsetails!
- Published: June 14, 2011
There are a privileged group of plants and animals that are considered “living fossils”; species so old and unchanged by evolution that they are almost exactly the same as they were millions of years ago. Today’s weekly wildlife is one of those “living fossils”: the horsetail.
The genus Equisetum contains many species of horsetails. These thin, reedy plants that you see clumped together at the edge of bogs and marshes are a hundred million year old relic. How fascinating that an organism could eke out a living so successfully that it would not have to adapt for such a long time!
