No, populations of organisms evolve, individuals are naturally selected.
The two factors required for a character of trait to change over time through natural selection are heritability of the trait and a differentiation of fitness between traits.

Evolution occurs through natural selection via survival of the fittest. This means that those organisms that are most well adapted to the environment will survive and pass on their genes.
Through ongoing natural selection a population adapts to its enviroment
Natural selection acts on the genotype, but indirectly, through the phenotype.
I recommend reading about "Survival of Fittest" and "Natural Selection" to answer your question. The answer to this question is VERY big. Well, if you want the simplest answer, diversity and selection of good traits within the population.
Adaptation is a future generation, and a natural selection is when the Natural Resources select the generation continued. Natural selection is the evolutionary driver of adaptive change. All organisms born are variations and the variation that survives and reproduces better than its conspecifics will have more progeny with the selfsame adaptation that helped the organism to survive and reproduce. Thus, through mutation leading to variation and mutations leading to improvements on that variation natural selection chooses and shapes the organism to be well adapted to its immediate environment.
These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.

Yes, penguins, like all animals, have gone through natural selection. Scientific evidence supports this notion.
There is no rate to evolution. Evolution is simply the following of natural selection within an environment. natural selection is like survival of the fittest. A mutation in the organism is caused which can start the natural selection process for that organism. If that organism is able to survive better with that mutation then the trait is passed down and slowly evolution takes place. The only way for evolution to happen at the same rate of another organism is if the organisms rely on each other and one goes through a change. The other dependent species will have to also go through an alteration in order to be able to survive. hope this helps!
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
