Deep-sea protists may explain trace fossil evidence attributed to ancient animals - (Cell Press) A new discovery challenges one of the strongest arguments in favor of the idea that animals with bilateral symmetry--those that, like us, have two halves that are roughly mirror images of each other--existed before their obvious appearance in the fossil record during the early Cambrian, some 542 million years ago. Researchers report the first evidence that trace fossils interpreted by some as the tracks of ancient bilaterians could have instead been made by giant deep-sea protists.... When it comes to what's for dinner, baboon society is no democracy - (Cell Press) In decisions about where to eat, baboons don't all have an equal say, according to a report in the Nov. 20 issue of Current Biology, a Cell Press publication. Rather, most baboons in a group will follow their leader to a dining spot of his choosing, even if it means a considerably more meager meal for themselves than they could have had otherwise....
