This study absolutely does not show that humans are evolving

yeah - a gene that kills you is less common in people over the age that it tends to kill you? SHOCKER! Also, super high testosterone dudes probably inseminate more women than betas and they probably die younger too.

Unless the statistical distribution of alleles is exactly the same (unlikely) from one generation to the next then humans would have to be evolving, wouldn't they?

Genetic drift is not usually considered 'evolving' because the variants are selectively neutral. That's why finding selected variants isn't as simple as 'SNP X is 0.00001% more common in generation 2 than generation 1, case closed!' - you are looking for variants which are becoming more/less frequent than would be plausible under simple drift. Just like an experiment where you know the effect will never be exactly 0 because of chance imbalances and random noise.
