Charles Darwin faced substantial personal struggles that influenced his theories of evolution. Following the loss of his mother and the pressure to conform to societal expectations, Darwin grappled with profound self-doubt. His voyages aboard the HMS Beagle exposed him to diverse species and ecosystems, leading to a deep reflection on the mechanisms of natural selection. Simultaneously, his own health issues and the death of loved ones heightened his sensitivity to the struggles of life, enriching his understanding of the interconnectedness of life forms. These experiences profoundly shaped his revolutionary work, pushing him to challenge established scientific beliefs.
