Artist’s rendering of a worm-like creature that lost its hind legs to Franz Anthony

A worm-like singularity from 518 million years ago is the oldest known animal to have lost body parts it no longer needs. Just as modern cave dwellers evolved to lose their eyes, ancient animals evolved to lose their hind legs.

“This is the earliest example in the fossil record of an organism with a secondary loss of body parts it no longer needs,” said Richard Howard of the University of Exeter, UK.

Facivermis yunnanicusis a worm-like creatureCambrian period, when the first complex animals evolved in the sea. It is less than 10 cm long and has 5 pairs of spiny legs in the front half while its tail is swollen.

In the past, it was difficult to determine the exact animal speciesF. Yunnanicusto be. “People have been saying for years that’s all,” says Howard.

He and his colleagues reexamined known specimens and studied new ones, all from the fossil collection from China known as the Chengjiang Biome.

The researchers found that some of the fossils were accompanied by a tube,F. Yunnanicuscleared up and then live inside. This implies that it is a filter feeder, similar to sometubeworms, it attaches its tube to a surface and catches passing food particles with its front legs.

Its closest relatives have long, hairy appendages for catching food, but they still have hind legs that they use to anchor themselves in place.

“Facivermis”It’s a specialized member of an already specialized group,” says Howard.

Analytics is also changing how we think aboutF. yunnanicuslocated in evolutionary history.

Some of the most primitive animals are basicallyworms. Initially, some of these worms split into two groups. One group, the Cycloneuralia, remained geneless: they gave rise to several modern worms, such as roundworms. The other, the lobopodia, developed legs. They form three groups of legs: arthropods, which include insects and spiders, velvet worms andtardigrade, also known as “Water Bear”.

The idea isF. Yunnanicusis the “missing link” from which the two fossil groups part. But Howard says that’s wrong because the animal has special eyes that identify it as a lobopodian.

“Our research shows that this worm is not a missing link,” he said. “It was a simplified Lobopodian, a Lobopodian who lost his leg. Its appearance makes it seem more primitive than the original.”

Where did the worms come from? These animals have been around since long before the time of the dinosaurs and their origins are actually pretty fascinating.
