As part of SMU’s Year of Darwin, Simon Conway Morris, Professor of Evolutionary Paleobiology in the Department of Earth Sciences at the University of Cambridge, spoke on “Darwin’s Compass: Why the Evolution of Humans is Inevitable.” He is renowned for his insights into early evolution and his studies of paleobiology.

Dino to Birds (Archaeopteryx) – www.warneveryone.com The origin of birds is largely a matter of deduction. There is no fossil evidence of the stages through which the remarkable change from reptile to bird was achieved. WE Swinton, Biology and Comparaitive Physiology, ed. AJ Marshall, Academic Press, NY, Vol. 1, p.11 Evolutionist Colin Patterson, a former senior paleontologist at the British Museum of Natural History, perhaps summed it up the best when he admitted that Archaeopteryx “has simply become a patsy for wishful thinking.” Archaeopteryx probably cannot tell us much about the early origins of feathers and flight in true protobirds because Archaeopteryx was, in the modern sense, a bird. . . . . .Paleontologists have tried to turn Archaeopteryx into an earth-bound, feathered dinosaur, but it’s not. It is a bird, a perching bird. And no amount of “paleobabble” is going to change that. Alan Feduccia, Evidence from claw geometry indicating arboreal habits of Archaeopteryx. Science 259 , February 3, 1993 At the morphological level feathers are traditionally considered homologous with reptilian scales. However, in development, morphogenesis [shape/form generation], gene structure, protein shape and sequence, and filament formation and structure, feathers are different. AH Brush, “On the Origin of Feathers,” Journal of Evolutionary Biology, 9:131-142, 1996 Even though we have no direct evidence for smooth transitions, can we invent a reasonable sequence of intermediate …

La ausencia de evidencia fósil de etapas intermedias entre las principales transiciones en el diseño orgánico, de hecho nuestra incapacidad, siquiera en nuestra imaginación, de construir intermediarios funcionales en muchos casos, ha sido un problema persistente y molesto para los relatos gradualistas de la evolución.” [Stephen Jay Gould (Profesor de Geología y Paleontología de la Universidad de Harvard), "Is a New and General Theory of Evolution Emerging?

This documentary describes effects of the last ice age – the Laurentide – on Upstate New York. This segment is an overview of Upstate’s geological and ecological history. It includes a fossil-hunting expedition to Quarry Farm by a paleobiology class at Elmira College. Quarry farm is the famous American humorist Mark Twain’s 19th century summer home near Elmira, NY. Excerpted from the television documentary “Footprints of the Ice Age: The Laurentide Ice Sheet in Upstate New York” produced and narrated by Michael S. Ameigh. This program premiered on WCNY-PBS Syracuse, NY April 19, 2009.

01 October 2009 sciencenow.sciencemag.org Researchers have unveiled the oldest known skeleton of a putative human ancestor–and it is full of surprises. Although the creature, named Ardipithecus ramidus, had a brain and body the size of a chimpanzee, it did not knuckle-walk or swing through the trees like an ape. Instead, “Ardi” walked upright, with a big, stiff foot and short, wide pelvis, researchers report in Science. “We thought Lucy was the find of the century,” says paleoanthropologist Andrew Hill of Yale University, referring to the famous 3.2-million-year-old skeleton that revolutionized thinking about human origins. “But in retrospect, it was not.” Researchers have long argued about whether our early ancestors passed through a great-ape stage in which they looked like protochimpanzees, with short backs; arms adapted for swinging through the trees; and a pelvis and limbs adapted for knuckle-walking (Science, 21 November 1969, p. 953). This “troglodytian,” or chimpanzee, model for early human behavior (named for the common chimpanzee, Pan troglodytes) suggests that our ancestors lost many of the key adaptations still found in chimpanzees, bonobos, and gorillas, such as daggerlike canines and knuckle-walking, which those apes were thought to have inherited from a common ancestor. Evidence has been hard to come by, however, because there are almost no fossils of early chimpanzees and gorillas. Until now, the oldest known skeleton of a human ancestor was Lucy, who …
