A worm that lived half a billion years ago preferred turning right. Fossils of Spriggina floundersi provide the earliest evidence of animals favouring one side of the body over the other – a feature of nervous systems that we see in our own right- and left-handedness

Trechos de apoio da pauta: Spriggina floundersi worms that bent to the right are preserved as fossils that bend to the leftScott Evans/AMNH A 555-million-year-old worm had a predilection for turning right, possibly indicating the oldest known example of handedness. Although these worms lacked limbs and so couldn’t be considered left- or right-handed in the way that we understand, the development of a tendency to favour one side over another is evidence of an advanced nervous system.
