Human Evolution Welcome to your Human Evolution 1. The first scientist who proposed his theory of evolution was Wallace Mendel Darwin Lamarck2. The prehistoric man which lived on Earth during late Pleistocene period was Australopithecus Peking man Atlantic man Neanderthal man3. The extinct human who lived 1,00,000 to 40,000 years ago in Europe, Asia and parts of Africa, with short stature, heavy eye brows, retreating forehead, large jaws with heavy teeth, stocky bodies, a lumbering gait and stooped posture was Ramapithecus Homo habilis Neanderthal human Cro-Magnon humans4. The cranial cavity of the modern man was 1300-1600 c.c 900-1000 c.c 600-900 c.c 450-650 c.c5. The theory of Natural selection was proposed by Mendel Lamarck Darwin Wallace6. Lamarckism cannot explain Weak muscles in the son of a wrestler Long, narrow, limbless body of snakes Webbed toes in aquatic birds Heterophylly7. The brain capacity of Homo erectus was about 650 c.c 900 c.c 1200 c.c 1600 c.c8. During a study session about evolution, one of your fellow students remarks, "The giraffe stretched its neck while reaching for higher leaves; its offspring inherited longer necks as a result". To correct your friend's misconception Characteristics acquired during an organism's life are not passed on through genes Overproduction of offspring leads to a struggle for survival Spontaneous mutations can result in the appearance of new traits Only favourable adaptations have survival value9. Which one of the following is not a vestigial part in human beings? Segmental muscles of abdomen Coccyx Finger nails Third molar on each side in each jaw10.
