In addition to biology, his theory has a great influence on the development of anthropology, psychology and philosophy. Engels listed "evolution theory" as one of the three major discoveries of natural science in the19th century (the other two are cell theory and the law of energy conservation and transformation), and made outstanding contributions to mankind.
From the perspective of evolution, different species living at the same time can be traced back to a common ancestor in the dimension of time. Therefore, according to the ancestral relationship, living and once-living creatures can be related to each other, and this biological evolution system representing the ancestral relationship is called phylogeny.
The phylogeny of organisms can be vividly represented as a tree: if the time dimension is represented as from the root to the top of the tree, the trunk represents the common ancestor, and the big and small branches represent the interrelated evolutionary pedigree, this constitutes the so-called phylogenetic tree or evolutionary tree.
The so-called evolutionary model is the characteristics of evolution in time and space, that is, the characteristics of systematic development, which are embodied in the morphology of evolutionary trees: the continuation and branching mode of branches, the inclined direction and spatial configuration of trunks, and the interruption of trunks. It represents the characteristics of midline evolution, species formation and extinction of phylogeny.

Darwin lived in the middle and late19th century, which was the first stage to get rid of ignorance and advocate science, which provided the ideological basis for Darwin to establish the theory of evolution by natural selection.
However, the long-distance travel as a teenager accumulated a lot of evidence for him, which triggered his thinking on species evolution and eventually formed a complete system. Undeniably, due to the underdevelopment of science at that time, there were theoretical defects in the theory of evolution, but with the continuous progress of science, the theory of evolution has developed into a modern comprehensive theory of evolution.
In fact, there is only one purpose to oppose evolution-to draw out God. Now these people who oppose evolution are very obscure. They don't talk directly about God's creation, but about intelligent design. However, there are only two possibilities for species to emerge, one is natural evolution and the other is creation.
Even if life on our earth was created by aliens, where aliens came from is still a question, or a question of evolution or creation. So considering the life in the universe, there are still only two possibilities: natural evolution and creation.
Darwin himself said, "The main pleasure and the only career in my life are my scientific works. Some of the most important scientific achievements were directly investigated during the trip. " Such as: Darwin's famous diary of investigation, beagle geology, beagle zoology, etc.
In his works, The Origin of Species is of great historical significance, which shows the gradual development of Darwin's theory of evolution and natural selection. The publication of the Origin of Species is a great event of world significance, because it marks the profound changes in the views of most learned people on the biological world and the status of human beings in the biological world in the19th century.
The publication of On the Origin of Species caused a fierce attack on Darwinism by creationists and teleological scientists (but most of them), and also caused a corresponding struggle to maintain Darwinism. In addition to Darwin himself, there were progressive naturalists who actively participated in this struggle, and they became enthusiastic supporters of Darwinism everywhere.
