Human Evolution Welcome to your Human Evolution 1. The brain capacity of Homo erectus was about 1200 c.c 1600 c.c 900 c.c 650 c.c2. The theory of Natural selection was proposed by Mendel Lamarck Wallace Darwin3. The first scientist who proposed his theory of evolution was Mendel Darwin Wallace Lamarck4. The extinct human ancestor who ate only fruits and hunted with stone weapons was Homo erectus Australopithecus Ramapithecus Dryopithecus5.

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 Spontaneous mutations can result in the appearance of new traits Only favourable adaptations have survival value Characteristics acquired during an organism's life are not passed on through genes Overproduction of offspring leads to a struggle for survival10.
