Think of evolution as a Monte Carlo simulation, the frequency of which follows the reproductive cycle of the organism. This is like 20 years for human, a few years for cats (allowing them to be selectively bred by people), and a matter of days for single-celled organisms. The toxoplasmosis creatures create a better environment for themselves by promoting cat ownership, it’s not necessarily the biological imperative of the cats to do so. So the toxins have self-selected over time to undermine human evolution.
This is the same reason that antibiotic misuse is so destructive.
