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 Only favourable adaptations have survival value Spontaneous mutations can result in the appearance of new traits7. The cranial cavity of the modern man was 600-900 c.c 1300-1600 c.c 450-650 c.c 900-1000 c.c8. The first scientist who proposed his theory of evolution was Lamarck Wallace Mendel Darwin9. The brain capacity of Homo erectus was about 1600 c.c 1200 c.c 900 c.c 650 c.c10.
