 A few species of giant seaweed known as Palmophyllales live at great depths and seem to defy evolutionary logic. NATURE International Weekly Journal of Science carries an analytical article based on recent findings by researchers at Belgium's Ghent University . We think you may find this article very interesting in much the same vein as other posts that we have published on deep sea life and lessons the deep sea floor (see Extreme Shrimp ), may hold for exobiology, the study of life on other planets. NATURE noted:

"A mysterious deep-ocean seaweed diverged from the rest of the green-plant family around 540 million years ago, developing a large body with a complex structure independently from all other sea or land plants. All of the seaweed’s close relatives are unicellular plankton."

"The finding, published today in Scientific Reports1, upends conventional wisdom about the early evolution of the plant kingdom. “People have always assumed that within the green-plant lineage, all the early branches were unicellular,” says Frederik Leliaert, an evolutionary biologist at Ghent University in Belgium. “It is quite surprising that among those, a macroscopic seaweed pops up.” Quoted from NATURE International Weekly Journal of Science
