2006Jean Moliner, Gerhard Ries, Cyril Zipfel and Barbara Hohn publish their findings on stressed plants that not only mutate at a greater rate, but also pass an increased tation tendency to their offspring.2006Zeresenay Alemseged and collaborators publish a cription of a 3.3 millionyearold partial skeleton from a juvenile Australopithecus arensis from Ethiopia. The remains indicate that the australopithecene toddler walked upright and climbed trees.2006Jin Meng and collaborators describe a Mesozoic gliding mammal that pushes back the origin of mammalian flight by 70 million years, and suggests mammals maybe dabbled in flight earlier than birds.2007Kate Trinajstic and collaborators announce the discovery of 380 millionyearold Australian fossil fish sporting fossilized muscle. 2007Xing Xu and collaborators describe Gigantoraptor erlianensis, a 25footlong, 3,000pound, birdlike dinosaur from Inner Mongolia. The find runs counter to earlier assumptions that dinosaurs necessarily got smaller as they acquired more features resembling those of birds.2007Fred Spoor, Meave Leakey and collaborators describe remains of Homo habilis and Homo erectus from the same rock layer a short distance apart. The finds suggest that the two species coexisted in the same area for up to 500,000 years, and that H. erectus probably did not descend from H. habilis as previously thought.
