Refuting Creationism - How Butterfly Genomes Confirm Darwin's Conclusion

[Body]

1,000 butterfly and moth genomes to investigate evolution, climate change resilience, and tackle food security issues

Geneticists at the Wellcome Sanger Institute have just completed the sequencing of 1,000 European butterflies and moths. Their results are already feeding into research papers, such as that by Asia E. Hoile, Peter W. H. Holland & Peter O. Mulhair, in BMC Genomics. The Wellcome Sanger team have published their results in Trends in Ecology & Evolution

In 1858, Charles Darwin and Alfred Russel Wallace proposed the theory of evolution by natural selection, or as they described it, the origin of species by the preservation of favoured races. Darwin then elaborated on that central idea and concluded that the ‘tree of life’ would branch in ways consistent with diversification from common origins.

Creationists, on the other hand, claim all species were created by magic in their present form just a few thousand years ago, with no evolution and no common ancestry.

Darwin's Tree of Life sketch

Neither Darwin nor Wallace knew anything about DNA or genomes, or that mutations in DNA would become ‘favoured’ in particular environmental niches, driving diversification. They developed their ideas purely from the observable morphological and behavioural similarities and differences among species.

So, if the creationists are right, what should we see in these 1,000 genome sequences?
