A bone in the heart of a chimpanzee: a mysterious process puzzled scientists

A bone in the heart of a chimpanzee

In some chimpanzees species , the scientists have discovered a bone in the heart. That discovery raises many questions. Researchers found this strange anatomical feature in age-related chimpanzees. And they came to the conclusion that bone can appear precisely with age and it is able to create a psychological mood. The size of that bone formation is only a few millimeters, but in different individuals it varies.

Researchers suggest that bone can be the cause of various types of heart failure, found not only in chimpanzees and primates, but also in cattle and buffaloes, as well as camels and otters. The discovery of bone in the heart in chimpanzees was a revelation, and the research team intends to conduct research on human anatomy.


The discovery of a new bone in apes is a rare and surprising event, because science is interested in whether such a bone can be in humans. Anatomist Catherine Rutland from the University of Nottingham said that she and her colleagues used a high-resolution scanning method to analyze the structure of the heart skeleton of large monkeys.

And the researchers noticed calcification growing in the hearts of some chimpanzees. By analyzing the tissue under a microscope, scientists came to the conclusion that these structures were from bone or cartilage, in some cases its composition was combined. Scientists do not yet have detailed information on the results of the study. They suggested two scenarios: the detected bone in the heart may simply be an anatomical feature of some individuals. But further studies show the opposite.

For example, in a person with age, mineralization of the heart muscles occurs, which is associated with cardiovascular diseases. It is possible that chimpanzees are not like humans, prone to problems with the coronary artery. But heart disease affects nearly 70 percent of individuals with age.


The most common disease is idiopathic myocardial fibrosis, which causes sudden cardiac arrest. In 16 examined age chimpanzees in only 3 cases in the heart of animals there were no signs of this disease. But in the hearts of those monkeys who were diagnosed with the disease, the formation of bone or cartilage was detected.
