[QUOTE]Originally posted by Masao: [QB] This is what I remember from college: The speed of change in a species (evolution) depends on a number of things, including the rate of mutation and the degree of selective pressure. Mutations arise through errors in DNA replication and damage to DNA through chemicals and radiation. The rate at which these errors occur may be low and stable (through chance mistakes) or may be higher or lower depending on the amount of radiation and mutagenic chemicals in the environment. These mutations are usually neither harmless nor beneficial and have no effect on the survival of the individual (or breeding success). Other mutations do effect survival, but how they affect survival can also depend on the enviroment. Some mutations are immediately fatal, of course, such as one that would cause us to be born without a brain. However, let's say a mutation causes us to grow thick hair all over our bodies rather than just on our heads. If one of us had such a mutation, it might decrease our chances of finding a mate and passing on the gene (unless a prospective mate likes dogs). On the other hand, if an ice age came along, such a mutation would quickly become beneficial by allowing us to survive the cold whether. The would survive to mate, and the gene would be passed on. So, Remans might evolve from Romulans quickly (100 generations) if selective pressures are strong and if mutations arise at a high rate (through increased environmental radiation or artificial induction).
