WG Bellringer • What is the name of the time zone that South Carolina is in? What about Chicago Illinois?
WH Bellringer: • Why does Evolutionary theory believe humans are descended from apes?
WOD: Circumvent • to go around or bypass “John circumvented the issue by changing the subject of the conversation.”
Piltdown Man • Eanthropus dawsoni or "dawn man“ • “Discovered” by Charles Dawson in 1912 (an ape-like mandible with human-like teeth and a human-like piece of skull) • Actually a hoax, but was accepted for 40 years as a real fossil!!
Nebraska Man • Hesperopithecus haroldcookii • Mr. Harold Cook discovered one tooth in 1922 in the “Pliocene” deposits of Nebraska • An attempt was made to use Nebraska Man as evidence in Scopes “Monkey” Trial • Drawing published in Illustrated London News, 1922
Turned out to be a tooth from an extinct type of pig (peccary)
Getting it in the Right Ballpark Sort of . . .
Evolutionary Sequence from ape to human
Ramapithecus lufengensis • In 1932 Louis Leaky discovered a broken jaw and teeth in southwest Kenya • When assembled, looked like it could be related to human • Really just the ancestor of the modern orangutan
Australopithecus • Australopithecus means "southern ape" – found in S. Africa • Tuang Child – Raymond Dart, 1924 • Also found other evidence, slender female and hefty male forms • “africanus” and “robustus”
Australopithecus afarensis "LUCY" • Discovered in 1974 by Donald Johanson • Angle of knee joint matched that of humans = obviously walked upright • ALSO matched that of tree climbing apes • Curved toe bones, longer arms than legs = similar to apes • Was Lucy just a tree climbing ape or did she walk upright? • Had larger big toes so she probably walked upright sometimes AND on her knuckles
Lucy is NOT the missing link • Footprint fossils dating to the same time period are MODERN human feet • Lucy is pre-modern, so other hominids existed at the same time • Johanson disagreed
Semicircular Canals • Fred Spoor, early 1990s • Used CT-scanner on fossil hominids • Inner ear canals are most similar to apes
Homo Habilis • “Handy Man” – first discovered in 1959 by Mary Leakey • Used tools, butchered animals • Later scientists de-classified him as just another Lucy-like hominid
Neandertal (Neanderthal) Man(Homo neanderthalensis) • Thought to have died out over 20,000 years ago. • First found in 1856 in Neander Valley, Germany, by Johann Fahlrott • Dozens of skeletons have since been found • In 1908, Professor Boule of thought this hominid was un-intelligent and apelike because of his stooped posture and thick bones
In 1950s it was found that Neanderthal man's average brain capacity was larger than modern man's by over 200 cc's. • Some also claim that Neanderthal man, at least the stooped over ones, suffered from osteoarthritis • What’s the latest “scientific” explanation? • Neanderthal man was an “evolutionary dead-end”
