I didn't detect any use of the "E" word at all. This article was primarily about psychology and genetics. It basically outlined the nature vs. nurture aspects of religious participation. I don't believe there was anything inflammatory or controversial about this article. Nor were there any beliefs reflected.
The E word is used and apparently our genetic codes just see things differently.
If by "E" word, you mean evolution; then you weren't reading too closely.
There is logic behind why humans may have evolved with a religious predisposition in their genes
it makes sense that evolution would favor a genetic disposition for spirituality
