If evolution were impossible, then humans couldn't do what this group has so easily done with foxes.

Another striking example is tusk size of the African elephant. About 80 years ago was a busy time in the ivory trade. The elephants with the biggest tusks were the first to go. As a result, almost none of the modern elephants have tusks that reach the huge sizes of those in years past.

The "big tuskers" sported a feature specifically detrimental to survival, were selected against, and the elephants of today reflect the bias towards smaller tusks.

Like you said, selection is selection.

Here is some more definitive information:

Although the tonnage of ivory on the international market remained relatively stable between 1979 and 1989, the size of the tusks decreased significantly. In 1979, the mean weight of traded tusks was 9.8 kilograms, but by 1987 the average tusk weighed was only 4.7 kilograms. Those elephants with larger tusks -- the elders of the herds -- have become very rare and that poachers are killing younger animals as well as females, with smaller tusks. Decreasing tusk size also means that more elephants need to be killed to obtain the same volume of ivory as before. Two other problems arise. First, the species' genetic resources are being reduced and weakened. Second, elephant behavior could be compromised as herd composition is fundamentally altered.
