Human Evolution Welcome to your Human Evolution 1. The extinct human ancestor who ate only fruits and hunted with stone weapons was Dryopithecus Ramapithecus Homo erectus Australopithecus2. 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 Overproduction of offspring leads to a struggle for survival Only favourable adaptations have survival value Characteristics acquired during an organism's life are not passed on through genes Spontaneous mutations can result in the appearance of new traits3. The first scientist who proposed his theory of evolution was Mendel Lamarck Wallace Darwin4. 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 Neanderthal human Cro-Magnon humans Homo habilis Ramapithecus5. Which one of the following is not a vestigial part in human beings? Third molar on each side in each jaw Finger nails Segmental muscles of abdomen Coccyx6. The brain capacity of Homo erectus was about 900 c.c 1600 c.c 1200 c.c 650 c.c7. Lamarckism cannot explain Weak muscles in the son of a wrestler Heterophylly Webbed toes in aquatic birds Long, narrow, limbless body of snakes8. The theory of Natural selection was proposed by Darwin Mendel Lamarck Wallace9. The prehistoric man which lived on Earth during late Pleistocene period was Australopithecus Atlantic man Neanderthal man Peking man10. The cranial cavity of the modern man was 450-650 c.c 600-900 c.c 1300-1600 c.c 900-1000 c.c11 out of 10Please fill in the comment box below.
