The great British natural scientist Darwin was the founder of the theory of biological evolution, but his great discoveries were unfortunately intertwined with family tragedies.

In January 1839, Darwin had a wedding with his uncle's youngest daughter, Emma. The bride was an elegant, virtuous, intelligent, and beautiful girl. Despite the mutual respect and love between Darwin and his wife, because they are cousins, their sincere union kicked off Darwin's unexpected family tragedy. After Darwin got married, Emma gave birth to 10 children. Among them, the eldest daughter Anna, Elizabeth, the second daughter Mary Eleanor and the youngest son Charlie Ferring all died at a young age. The other 7 children also suffer from various diseases of varying degrees. Darwin's second son George, third son Francis, fifth son Horace, and unmarried fourth daughter Elizabeth all suffer from mental illnesses of varying degrees. The other three children. The eldest son William, third daughter Henryetta and fourth son Leonard have no obvious symptoms of psychosis, but they have no offspring after marriage.

According to textual research, Darwin’s family had a mysterious disease for a long time, and this disease has been manifested very clearly in Darwin’s generation. Darwin suffered from "psychiatric depression" since middle age, which afflicted Darwin for the rest of his life. Due to the marriage of close relatives, the disease of the Darwin family was fully manifested in the offspring. Good inheritance is the prerequisite for prenatal education. If Darwin lives in today's technological development, such a tragedy may not be staged.
