Charles Darwin had five siblings: three brothers—William, Erasmus, and Richard—and two sisters—Caroline and Susan. His siblings played various roles in his life, with some supporting his scientific endeavors. Erasmus, in particular, was known for his interest in science and literature, which influenced Darwin’s thinking. The Darwin family was close-knit, fostering an environment of intellectual curiosity.
He had 6 children: Marianne Darwin (1798-1858) Caroline Sarah Darwin (1800-1888) Susan Elizabeth Darwin (1803-1866) Erasmus Alvey Darwin (1804-1881) Charles Robert Darwin (1809-1882) Emily Catherine Darwin (1810-1866)
Charles Darwin had five siblings: his older sister, Marianne; his older brother, Erasmus; his younger brother, Charles; and two younger sisters, Caroline and Susan. His family was relatively large, and he maintained close relationships with many of his siblings throughout his life.
AnswerCharles Lyell, lawyer and geologist who developed the theory of uniformitarianism in geology is commonly recognised as the one person who had the most profound influence on Darwin. Captain Fitzroy with whom Darwin sailed on his famous voyage on the Beagle, gave Darwin a copy of Lyell's 'Principles of Geology'. It is difficult to say who had the second greatest influence, but certainly his grandfather Erasmus Darwin, who himself wrote on Evolution had a great influence.
