Detailed explanation-1: -After a heart attack on Christmas, followed by seizures, Charles Darwin dies, in great suffering, at Down House. He is later buried in Westminster Abbey.

Detailed explanation-2: -Publication of his journal of the voyage made Darwin famous as a popular author. Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations and, in 1838, devised his theory of natural selection.

Detailed explanation-3: -In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship’s naturalist for a trip around the world. For most of the next five years, the Beagle surveyed the coast of South America, leaving Darwin free to explore the continent and islands, including the Galápagos.

Detailed explanation-4: -Darwin died just before 4 pm on 19 April 1882, not of his lifetime illness but apparently of a heart attack. Surprisingly no one seems to have considered whether he might have had a perforated peptic ulcer that would explain the severe pain and haematemesis he had at the time of death.

Detailed explanation-5: -Darwin became fully devoted to earthworms in the spring of the year, just after finishing the manuscript of Movement in plants, his most ambitious botanical book. Both projects explored the complexities of movement, forms of sensitivity, and the ability of organisms to adapt to varying conditions.
