Rains which Bring a Dead Land Back to Life

As well as bringing water, an essential requirement for living things, to the earth, the rain also has a fertilizing property. Drops of rain which evaporate from the sea and reach the clouds contain certain substances which "revitalize" dead soil. These raindrops with such "revitalizing" properties are called "surface tension droplets."

The Misconception about Macromutations

One rule, put forward by R. A. Fisher, one of the last century's best known geneticists, and based on observations, clearly invalidates this hypothesis. Fisher states in his book The Genetical Theory of Natural Selection that the likelihood that a particular mutation will become fixed in a population is inversely proportional to its effect on the phenotype.1 Or, to put it another way, the bigger the mutation, the less chance it has of becoming a permanent trait within the group.
