Differential selection is just that, differential. Some variation is marginally superior to another variation us fitness difference, so the key is to have variation. Then natural selection will " see " this slight variation and select the better adapted trait against the background of the immediate environment.
differences in the characteristics of individual trees
It is no longer Darwin's theory, as Darwin has been dead about 130 years. There are no credible alternatives to the modern theory of evolution by natural selection. So, the differences is; the theory of evolution by natural selection is supported by myriad lines of converging evidence and explains the natural phenomenon that is evolution very well. The " conflicting theories " have no evidence supporting them and explain nothing.
It is called evolution. After all, all characteristics, as far as evolution is concerned, are intermediate. They're all temporary variants, on their way to becoming something else.
The term that is often incorrectly used to describe evolution by natural selection is "survival of the fittest."
All of these terms EXCEPT ___________ contribute to natural selection
If there is not reproductive fitness conveyed by a variant trait, then natural selection has nothing to select and nothing to promote into the populational gene pool.
Variability, heredity, and natural selection are 3 main things that contribute to evolution.
Selection is not always of the most fit to survive.
they contribute to biological evolution by how they've affected the evolution rate by increasing it or decreasing it
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.

The question answers itself: the characteristic is passed onto few or no offspring, and therefore will not spread throughout the population.
No, natural selection is believed to result in evolution.
Natural selection is one of the 'guiding' principles of evolution.
Perhaps not, but evolution can exist without natural selection.
