Whether the subject is evolution or climate change, the purpose of accusing someone of “science-denial” is to keep that person in line.
Wallace was the co-discoverer with Charles Darwin of the theory of evolution by natural selection. He later broke with Darwin over the question of teleology.
As I asked in a previous post: Why is Alfred Russel Wallace today a comparatively little known figure next to Darwin?
Despite the notoriety of Wallace in his own day, he remains a comparatively obscure figure in the history of biology.
Wallace broke with Darwin and became, arguably, the founding father of modern intelligent design theory.
