The origin of animals: can molecular clocks and the fossil record be reconciled?
The evolutionary emergence of animals is one of the most significant episodes in the history
of life, but its timing remains poorly constrained. Molecular clocks estimate that animals …

A macroscopic free-swimming medusa from the middle Cambrian Burgess Shale
Cnidarians are regarded as one of the earliest-diverging animal phyla. One of the hallmarks
of the cnidarian body plan is the evolution of a free-swimming medusa in some medusozoan …
