New research from Australian husband and wife scientists rewrites the received scientific wisdom of the origins of life,  and offers new hope for treating disease.

Modern scientists have agreed all life comes from a single cell. But University of Queensland Professors Bernie and Sandie Degnan say they can find nothing to support the theory.

Through genetic mapping, they've traced back the genetic lineage of animal life to an origin more closely resembling sea sponge stem cells, which have similarities to human stem cells. Bernie Degnan explains to Kathryn Ryan.
