Animals

Interpretation

The tree of life on Earth is big and messy, suggesting it would not be improbable to find life on other planets.

The strangeness of the animals discovered in the Burgess Shale strained the efforts of many including Wolcott to force them into existing phyla. Today, scientists are more likely to create new phyla to accommodate these creatures. Many of these animals are arthropods, that is, invertebrates with exoskeletons.
