Research Team Finds First Evolutionary Branching for Bilateral Animals
September 23, 2009
In the most computationally intensive phylogenetic analysis to date, an international research team led by Brown University has found the first evolutionary branching for bilateral animals. The researchers determined that the flatworm group Acoelomorpha is a product of the deepest split within the bilateral creatures -- multi-celled organisms that, like humans, have symmetrical body forms. Results appear online in Proceedings of the Royal Society B.
