Discovery of Quaestio simpsonorum Sheds Light on Early Animal Evolution

The 555-million-year-old fossils reveal the earliest known evidence of bilateral symmetry and mobility in animals.

Quaestio simpsonorum, discovered in the Australian outback, is one of the earliest known animals capable of movement.
The fossilized remains show clear left-right asymmetry, marking a significant evolutionary development in complex lifeforms.
This ancient species, resembling a 'sea Roomba,' likely moved along the seafloor consuming nutrients from algae and bacteria.
The discovery provides insights into the genetic mechanisms that may have driven the origins of complex life on Earth.
This find contributes to understanding the Ediacaran period, a time when multicellular life first evolved, offering a glimpse into early ecosystems.
