I don’t think modern medicine has impacted the mechanism of natural selection as much as cheap and quick international travel. Genetic drift is more pronounced in isolated populations vs. a population that has the influx and free mingling of new genetic material.
Love does not screw up natural selection. Even Darwin recognized sexual selection as one of the mechanisms of evolution.
Points to ponder: Has the inclusion of modern medicine (in regards to longevity and fecundity) with Western morality (the sanctity of all life) allowed for genes that may have been selected against to spread within the general population? Should society recognize this and start a eugenics program to “weed out” undesirable genes? Is the Human Genome Project just the start of such a program? Should breeding be controlled? Does humanity have the foresight to control its own destiny?
