organisms compete for shelter
In population genetics the frequency of individual alleles remain constant as long as alleles are neither selected for or against.
Phenotypic frequency varies based on the relative frequency of the various dominant and recessive alleles in the population.
Further, if selection is taking place phenotype will tend to change in the direction of the allele selected.
If the population is small enough there is also the factor of genetic drift, which can change phenotype in one direction within a few generations.
Populations are certainly being acted on and alleles selected whether they are obvious phenotypically...if these traits are linked with ones that are visually apparent the change will manifest phenotypically but the change occurs because of linkage to the selected trait as opposed to by selection for the phenotypically obvious one.
Some traits give an advantage.

Yes and the successful phenotype was made by a successful genotype which actually changes allele frequency in evolution.
Allele frequencies change randomly each generation. APEX
Chemical evolution: the evolution of the elements (building blocks of matter) biological evolution: the small scale change in a population that can be passed from generation to generation Both of these are changes that occur to gradually create a new species or substance
population dynamics-Population dynamics is the study of the factors that influence these changes in a population's size
There are 3 things that can be harmful if it reduces the organisms for survival and reproduction. The three things are changes in DNA, changes in phenotype and mutation .
Competition between organisms would most likely cause the phenotype frequency in a population that changes each generation.

Because peoples appearances changes as their body changes.

B) that a harmful phenotype may become an advantageous phenotype when the environment changes
