"While several organ systems have been investigated, such as the nervous system, the anal opening has been largely neglected", Dr. Hejnol told BBC Earth. The study, published in the journal Zoologischer Anzeiger, identified genes known as brachyury and ParaHox, which are crucial to the development of an anus. According to a report by Matt Walker at the BBC, their study reveals how the anus is perhaps one of the most important organs in our body, helping our digestive system work.<unk> According to a report by Matt Walker at the BBC, their study reveals how the anus is perhaps one of the most important organs in our body, helping our digestive system work.
