What Science Backs Up, We Disregard

Evolutionary theory in its basic form states that random mutations in the genes of an organism produce some genes that are advantageous, which lead to that organism being more adaptive to the changing environment. Over billions of years, these genetic changes produce organisms with the diversity and complexity we see today. ...

The evidence for evolution is staggering, from fossil records to chemical and anatomical similarities between species, to geographic distribution of related species to, most recently, genetic analysis. These studies of the genomes of various species show how genes have evolved among different species while still keeping their basic structure or have remained identical from one species to another.
The higher the percentage of identical genes between species the closer they are to having had a common ancestor. For example, humans have 45% of their genes identical to that of yeast, 60% identical to fruit flies, 90% identical to chickens, 95% identical to rabbits and 98% identical to chimpanzees.
But even though the overwhelming majority of scientists regard evolution to be the bedrock of biology (estimated at 99.9%), and even though the Catholic Church has accepted evolution as a guiding principle of biology, there is a small but vocal group of scientists, mainly at the Discovery Institute, who have promoted a pseudo-scientific version of creationism called Intelligent Design.

Why is this so? This is exceptionally interesting to me.
