Is There a Disease That Makes us Love Cats?
Evolutionary biologist Jaap de Roode, who looks into how parasites and their hosts co-evolve, teamed up with TED-ED to create this video. It covers toxoplasmosis and some of the big questions around it that remain unanswered. Cases of the disease go back as far as ancient Egypt and it’s caused by a parasite that only reproduces in the intestines of cats.
De Roode postulates that it might be this disease that has made us love cats and treat them so well so it can survive.
