What would it mean to the population geneticist if no ecological cause was discovered to account for an observed evolutionary result?

You might get more answers if you asked these questions on evolution in the biology section. Evolution is a biological theory, not an earth science theory. Your typical rock doesn't have DNA.
Many neutral and even some detrimental traits can persist in populations for many, many generations. Some of these traits are artificially selected by the individuals during mating rituals, some are artificially selected by humans, so not all traits you find in a population will be the result of natural selection, although given enough time, detrimental traits will be weeded out.
Also, just because an 'ecological cause' has not been found, doesn't mean it doesn't exist. There is a LOT we don't know. So what it would mean to a population geneticist is that there is plenty to still study.
