Numerous authors have examined the influence of other thinkers on Darwin’s formulation of some of the key concepts of the theory of evolution. Amongst those, Alexander von Humboldt often stands out – a scholar who, following his intention to explain the interconnection of various parts of the natural system, seems to tackle the question of evolution but does not offer an explicit answer. In this article, I examine Humboldt’s thoughts on evolution and the origin of species and evaluate his contribution (...) to Darwin’s theory of evolution. First, I analyse and explicate the fundamental assumptions and goals of Humboldt theory, and compare them to Darwin. Moving forward, I highlight the similarity of their methods, and argue that Humboldt and Darwin conduct similar investigation of fossil record and geographical distribution of species. Finally, I show that Humboldt acknowledges essential elements of Darwin’s theory of evolution: evidence given by fossil records, struggle for survival and relation between natural environment and living organisms. Humboldt, however, concludes we cannot know the evolution of species. I explain this stance, and contend that theories of Humboldt and Darwin turn out to be more similar than they seem, yet their different conclusions regarding the evolution of species stem from different initial assumptions underlying their respective frameworks.

Este artículo testa la generalizada aceptación experta que detecta en _Journal of Researches _de Darwin una influencia estilístico-ideológica proveniente de las obras de Humboldt. Para ello, dado que las descripciones de la naturaleza Humboldt y Darwin deberían contener implícita la concepción de la naturaleza de cada autor, se han analizado comparativamente pasajes dedicados al análisis descriptivo del influjo del paso del tiempo sobre el paisaje geológico en _Journal _y en _Ansichten der Natur _de Humboldt. Se demuestra así que la descripción (...) de la percepción humboldtiana del tiempo deja entrever una concepción de la naturaleza romántico-naturalista que asume el tiempo y su influjo en la naturaleza como objeto estético. Por contra, a la descripción de la percepción darwiniana del tiempo subyace una concepción científico-naturalista que utiliza el concepto del tiempo como herramienta especulativa para el análisis científico del paisaje geológico.
