El dilema de Darwin

The video explores Charles Darwin's revolutionary ideas on evolution, which he developed after observing species differences during his 1831 Galapagos expedition. Despite the prevailing belief in divine creation, Darwin's theory suggested species evolved from common ancestors. Alfred Russell Wallace, a self-taught naturalist, independently conceived a similar theory, prompting Darwin to publish his work. In 1859, Darwin's 'Origin of Species' laid the foundation for evolutionary biology. While Darwin became a renowned scientist, Wallace's contributions were largely forgotten, though he considered himself a staunch Darwinist.
