Abstract in brief
The study suggests that tardigrades (water bears) originated from Cambrian lobopodians, extinct soft-bodied worms with primitive limbs, and share a common ancestor with a group called luolishaniids.
Morphologically, the ancestral tardigrade likely had a worm-like body without segmental plates, with lobopodous legs ending in claws, and features around the mouth, but no digits, which challenges previous ideas about their origins.
The highly compact body plan of modern tardigrades evolved after they diverged from this common ancestor, indicating that their small size and body structure are a result of later evolutionary changes.]
