genetics doesn't have to observe anything for millions of years to observe to results of evolution.

  You are downvoted, but I believe science is on your side. Just one recent article on the "Island rule": http://rspb.royalsocietypublishing.org/content/284/1857/20171065 http://rspb.royalsocietypublishing.org/content/284/1857/2017...

    The Atlantic tomcod in the Hudson River has evolved immunity to the PCBs dumped in the river by General Electric. http://news.nationalgeographic.com/news/2011/02/110217-hudson-river-pcb-fish-evolution-water/ http://news.nationalgeographic.com/news/2011/02/110217-hudso...

  There was an article linked on HN awhile back about getting bacteria to evolve resistance to antibiotics in just a few days.

    That is possible because the generation time of many bacteria can be measured in hours or minutes. The generation time in humans is ~25 years (possibly a bit higher in the western countries mentioned) So there could be hundreds of bacterial generations in a few days, but only ~2 human generations in the time period covered by this study. Selection would have to be extremely strong (the strongest ever observed by far) for the sperm count decrease to be primarily related to selection.

  and yet my initial comment makes no mention of evolution, i'm talking about hormones being released or not being released because they are too many of us.
