The objective of this article is scientist have found evidence that sexual orientation is largely determined by genetics, not choice. The author provides a positive evidence to support the object because he breaks down different examples to explain. The author in this article gives plenty of information that allows the reader to verify their major premises. The author shows quantitive data of blood and saliva samples taken from 409 pairs of open gay brothers, including non-identical twins, from 384 families. No statistical analyst was applied to their data. I think there was plenty of scientific evidence throughout this article, to me it just needed more statistics to trust the report. The author could have had a graph to present a better article.
