In modern terms, selection refers to :
1. inheritance of dominant characters
2. differential reproduction
3. a decrease in allele frequency in a population
4. differences in the contribution of various genotypes to the next generation

A mutation appears in a sub-population of organisms separated from the other group by in the same large geographical area. This mutation can spread to the other subgroup by:

2. mutations in the gene pool of the other subgroup
3. mutation pressures
4. crossovers

In Darwinian terms “fitness” can best be described as:
1. ability of organism, relative to others in the population, to pass its genes to next generation
2. the number of mates the organism has during its life time
