The Voyage of the Beagle
Charles Darwin was invited to be a naturalist on a scientific expedition that lasted five years. He noticed animals that were like animals from his homeland, but developed different traits. This observation went against religion. At that time, it was believed animals never evolved. Living things were creations of God and began and continued to be in the same form he intended. After the expedition, Darwin continued researching his observations which led to his theory of natural selection. -
The Origins of Species
The recorded data Charles Darwin gathered from the voyage of the beagle helped form Darwin’s theory of natural selection. He published the Origins of Species which explained his theory of natural selection. He believed that organisms evolve and develop traits that help them survive and reproduce in their environments. The traits that didn’t help the organisms would die off. He also believed that all organisms came from a limited group of ancestors and that the organism evolved over time. -
Descent of Man
Charles Darwin used his theory of natural selection to help him develop his theory over human evolution. He published Descent of Man which explained his theory on how humans have similar traits as primates and the possibilities of primates were our ancestors. This theory is still used today among philosophers and scientists. -
Expression of the Emotions in man and Animals
Charles Darwin believed humans and animals showed similar emotion behavior. This theory wasn’t popular at the time. Today, many psychologists agree with his theory and believe that there is a set of universal emotions used along humans and animals: disgust, surprise, fear, anger, sad and happiness. -
