Dawkins begins with the question, "Did everything in Creation fall together by chance or was there an intelligent designer like God?
" He then looks at the spreading disaffection with Darwinism and argues that it should not be written off as a worn out declaration of scientific faith.
As a result, evolutionary theory was "both permissible and respectable" by 1876.
For decades the Roman Catholic Church avoided official refutation of evolution.
Although evolution was unchallenged, uncertainties about the mechanism in the eclipse of Darwinism persisted from the 1880s until the 1930s inclusion of Mendelian inheritance and the rise of the modern evolutionary synthesis.
When Charles Darwin published his 1859 book On the Origin of Species, he convinced most of the scientific community that new species arise through descent through modification in a branching pattern of divergence from common ancestors, but while most scientists accepted that natural selection is a valid and empirically testable hypothesis, Darwin's view that it is the primary mechanism of evolution was generally rejected, in favour of alternative mechanisms.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 theories, but eventually came to receive overwhelming acceptance in the scientific community.The observation of evolutionary processes occurring (as well as the modern evolutionary synthesis explaining that evidence) has been uncontroversial among mainstream biologists since the 1940s.The ideas that species change over time through natural processes and that different species share common ancestors seemed to contradict the Genesis account of Creation.Believers in Biblical infallibility attacked Darwinism as heretical.
