"The Present State of Organic Nature Lecture I. (from VI.), "Lectures for Workmen," in the Museum of Applied Geology, 1863, based on Darwin's work: "The Origin of Species." In this lecture, the outstanding English biologist Thomas Henry Huxley offers his thoughts on the study of organic nature and presents his own vision of the evolution of living beings using Charles Darwin's "Origin of Species" as an example. The author examines the key questions of Darwin's theory regarding the selection of nature and the adaptation of species to changes in the environment. The lecture raises relevant topics related to the development of the scientific world in the second half of the 19th century and reflects the modern understanding of evolutionary processes. This work is considered one of Thomas Huxley's important contributions to the development of biological science and philosophy."
