A study about mutations that might confer benefit to high-altitude Sherpas is being announced as an example of evolution, but variation within species is not Darwinian evolution.
Some evolutionary papers are filled with verbs like arose, emerged, and originated. Do these convey scientific understanding, or are they veils concealing ignorance? Is it like saying "abracadabra" to say something "arose" by evolution? A recent paper about sophisticated metabolic enzymes in plants is a case in point.
It remains one of the biggest obstacles to belief in evolution that a random, unguided process could build an eye, a wing or any of thousands of complex structures.
