How the humble sea sponge helped scientists unravel a 700 million-year-old mystery of evolution
In a momentous breakthrough, Australian scientists have found that humans, and most likely the entire animal kingdom, share important genetic mechanisms with a jelly-like sea sponge that comes from the Great Barrier Reef.
Published in one of the most prestigious journals ‘Science’, the breakthrough reveals that some elements of the human genome (an organism’s complete set of DNA) are functioning in the same way as the prehistoric sea sponge. Incredibly this means it has been preserved across 700 million years of evolution. This mechanism drives gene expression, which is key to species diversity across the animal kingdom.
The findings are a fundamental discovery in evolution and the understanding of genetic diseases, and will help drive future biomedical research activities.
