Brittle star fossils from Gotland provide unique insights into evolutionary change
A research team has succeeded in analysing two temporally consecutive species of fossilised brittle stars. The findings show that a marine catastrophe 428 million years ago contributed to a radical change in the animals’ appearance. The new study clarifies how environmental disruptions can set off major evolutionary processes. Brittle stars are a group of echinoderms that are closely related to st
