All animals go to the toilet. In this case, mammals have one interesting feature: according to a recent study, all representatives of this class go “in large” the same amount of time.
12 seconds – this is how much the defecation process takes in the mammal, regardless of its size: whether it’s a domestic cat or a huge elephant. This time was established by scientists from the Georgia Institute of Technology during the observation of animals from the zoo in Atlanta. In the field of study were 34 representatives of the animal world, among them were elephants, pandas, warthogs and just local dogs living in the zoo. In addition, dozens of video materials were examined and the work of other research groups was studied. It is noted that the animals coped with their deeds in about 12 seconds regardless of body weight, length of the rectum or stool size.
Specialists found that all mammals in the process of defecation create the same internal pressure, but their different species are very different in the amount of mucus that is produced by the glands of the intestine. This mucus envelops the walls of the intestine and facilitates the rapid removal of masses from the body. It turned out that the larger the animal, the thicker the layers of mucus in its intestines.
Scientists have noticed that the same time of excrement in mammals is easy to explain by evolutionary way. Probably, this is the minimum possible time for which the body is able to get rid of accumulated excrement. During this procedure, the animal has to be in a certain position, which makes it unprotected for predators, so the evolutionary processes shortened the defecation time to the minimum possible, considering the biologically similar structure of all mammals.
