Cannibalism is common in the animal kingdom. It may be strange to think of real-life “battle-royales” playing out in such a way that many people participate and only a few emerge victorious, but in lands that are pleasant to watch. we need that. According to researchers at the University of Jyväskylä, Finland, in addition to the big difference, there is a relationship between eating or eating tadpole frogs.
The fathers of the bitter frog, Dendrobates tinctorius, take their tadpoles to small ponds where they are confined until metamorphosis. Squid of these species are important foods and the resources of these small ponds are limited. Therefore, there is fierce competition among people for the resources to survive until metamorphosis. While these herdsmen have become a battleground for war-royale among tadpoles, there are times when more than one survivor becomes a frog, indicating that sometimes the creatures let go. Eat each other. This led a research group founded at the University of Jyväskylä to think: What are the most important decisions between people who can eat each other?
The researchers thought that anger could be triggered by the relationship, the big difference, or the combination between the two forces. Biologically, there is a tendency for siblings to be more tolerant of each other. First, tadpoles have a kind of separation from the unrelated, and second, even if they separate from the younger siblings, they “keep” them from leaving them alone. Alternatively, anger can be determined through physical examination, which reveals significant differences to tadpoles in terms of someone’s ability to compete. In principle, we assume that the greater the differences between the competitors, the lower the overall anger, because a small competitor is more likely to eat while standing for more food.
Researchers are amazed to see how cannibals treat the people they fight (for a while). They found that those with big breasts were half as big as their younger brothers and sisters. That is, cannibals can discriminate against their siblings and change their behavior accordingly.
Thanks to this research, we have gained more information to better understand the other perceptions of parents when placing their young children in ponds inhabited by cannibals – As a result, it is difficult to find senior nurses in the forest, and parents can find them. put their youngsters in a high -altitude swimming pool with an older brother who they believe lacks easy food for the family.
The research is published in Personal Environment.
