Charles Darwin was too scared to release his theory of evolution as it would be strongly opposed by the religious as it contradicts the book of Genesis; added his wife was a strong Catholic. This was a time where many theories such as these came to light and opposed the scriptures. The same way the scriptures were ridiculed by those who ruled a nation the times before and proclaimed themselves as the ultimate being, and early humans fighting amongst themselves to take a lead position and rule others, the first early nuclear family fighting over what role they should play to protect themselves from dying because of hunger or being prey to other animals or climate.
