It's true that doggy style is a popular position among most animals, but to suggest that humans are the "freaks in the sack" for our preference of the missionary position is inaccurate. The missionary position is a classic option that has been around for centuries, and is popular among humans for a number of reasons. For one, it is a position that allows for a high level of intimacy, as both partners are facing each other and can make eye contact. Additionally, it is a position that can be adapted to the needs of the couple, as the top partner can vary the angle of penetration to receive more or less stimulation.
It is also important to note that humans engage in a wide range of sexual activities and positions, and while missionary might be the most popular, it is certainly not the only option. The truth is that humans are quite creative in the bedroom, and have developed a variety of positions and activities that are unique and distinct from those of other animals. To suggest that the missionary position is "novelty" for humans is to ignore the vast range of sexual expression that humans engage in.
Ultimately, while doggy style is a popular option among animals, it is inaccurate to suggest that humans are somehow "freaks" for engaging in missionary. Humans have a wide range of sexual expression that is unique to our species, and to discount that would be to ignore the vast possibilities of human sexuality.
