Darwin - Theory of Evolution
Charles Darwin would publish his profound theory that all life descends from a common ancestor. Organisms would randomly mutate over time, and the complex mutations that would aid survival would become predominately evident. This process was most popularly known as natural selection, where an organism would inherit genetic traits pertinent to their environment that would help them survive. -
Darwin - The Decent of Man
Darwin, with the help of his wife, daughter, and colleagues, published his book regarding the decent of man from pre-existing figures.Not only did this text focus on physical traits, but also human decent and ethics, and differences between sexual selection. This theory argued mind/body dualism, and focused on narrowing similarities in characteristics between humans and animals. He primarily used the characteristic traits between baboons, dogs, and savages to support his theory. -
Darwin - The Expression of Emotion in Man and Animals
Although this theory was originally addressed in his "Decent of Man" publication, he thought to narrow the focus on personality and psychological traits. The purposes of this publication was to describe, in detail, the idea of expression and emotion by initial voluntary action followed by an overflow of emotion suppressed by the nervous system into more basic expressions. How the most basic and complex emotions that surfaced from specific organisms and their exposure to adverse scenarios. -
Darwin - The Formation of Vegetable Mould through the Action of Worms
Darwin published his ideas that worms have played an integral part of our history. Due to worms ability to take in and excrete any material, they allow movement of earth which have resulted in the preservation of many ancient objects that have resurface over time. They are also responsible for the denudation of soil, improving soil quality, and the degradation of rock. This has allowed an natural flow on the earth surface by such a simplistic organism.
