Charles Darwin published 'The Descent of Man' in 1871, a pivotal work that expanded on his theories of evolution and natural selection. In this book, he explored the biological and social aspects of human evolution, arguing that humans share a common ancestry with other species. This publication not only challenged contemporary views on humanity's place in the natural world but also laid the groundwork for modern evolutionary biology.

Charles Darwin's 'The Descent of Man' (1871) not only revolutionized biology but also inspired poets like T.S. Eliot and W.H. Auden to explore themes of evolution, identity, and the human condition. This work prompted a re-examination of humanity's place in nature, influencing modernist poetry's existential inquiries.
