It filters individuals within populations. Populations (or their aggregate genetic makeups) are the results of this filtering, not the objects. It's open to debate whether it's better to consider the objects of the filter to be alleles, genotypes, or individuals.

No, that doesn't follow logically. You seem to believe in general that properties of wholes must be properties of parts and vice versa. That's simply not true. Individuals are selected, and the result is that allele frequencies change within populations. The former is selection, the latter is evolution.

NO it wasnt' because the outcome was predetermined, you knew you would get a date. the agency made a selction at random
