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 Only favourable adaptations have survival value Overproduction of offspring leads to a struggle for survival Characteristics acquired during an organism's life are not passed on through genes Spontaneous mutations can result in the appearance of new traits9. The cranial cavity of the modern man was 900-1000 c.c 1300-1600 c.c 600-900 c.c 450-650 c.c10. The brain capacity of Homo erectus was about 1600 c.c 900 c.c 1200 c.c 650 c.c11 out of 10Please fill in the comment box below.
