Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
The actual statement of the Scientific Dissent from Darwinism is a relatively mild one that expresses skepticism about the absoluteness of 'Darwinism' (and is in line with the falsifiability required of scientific theories) to explain all features of life, and does not in any way represent an absolute denial or rejection of evolution.

Some people are indoctrinated against the theory of evolution and simply do not think about it. But evolution is a well-established explanation of how life developed on Earth.
Anaximander's hypothesis could be considered "evolution" in a sense, although not a Darwinian one. [10] Empedocles argued that what we call birth and death in animals are just the mingling and separations of elements which cause the countless "tribes of mortal things". [11]
Evolution is an inevitable result of imperfectly copying, self-replicating organisms reproducing over billions of years under the selective pressure of the environment. The outcome of evolution is not a perfectly designed organism. The end products of natural selection are organisms that are adapted to their present environments.
[44] [5] [6] [7] In fact, genomic research has shown that hybridization between substantially diverged lineages is the rule, not the exception, in human evolution. [4] Furthermore, it is argued that hybridization was an essential creative force in the emergence of modern humans.
Marston [113] [114] has argued that, although the creationism argument (that because evolution is "merely" a theory, it therefore cannot also be a fact) reflects a fundamental misunderstanding of the concepts, the scientific countering of the creationist position by the simple stipulation that evolution is a fact may be counterproductive; a ...
