Variations are differences between groups of organisms of one species. Mutation is one source of variation between different groups within a species. The variation of organisms within a species increases the likelihood that at least some members of the species will survive under changed environmental conditions.<\/p>\n
Only mutations that occur in sex cells can be passed on to the offspring. Mutations which occur in other cells can be passed on to other body cells only. The experiences an organism has during its lifetime can affect its offspring only if the genes in its own sex cells are changed by the experience.<\/p>\n
Evolution is the consequence of the following factors:<\/p>\n
Some characteristics give individuals an advantage over others in surviving and reproducing, and the advantaged offspring, in turn, are more likely than others to survive and reproduce. The proportion of individuals that have advantageous characteristics will increase.<\/p>\n
