Rhythm was not inherited by Beethoven

Genetic research has led to a surprising conclusion that a child’s success cannot be accurately predicted based on heredity. This revelation was made through a study conducted by the Max Planck Institute, focusing on psycholinguistics. Professor Simon Fisher and his team discovered characteristics related to musicality that were inherited from Ludwig van Beethoven. The results of their research were published in the journal Current Biology.

Beethoven’s genetic inheritance was analyzed last year using his surviving hair. Researchers calculated a polygenic sum from his genes, which indicates the hereditary tendency to follow and detect rhythm. This sum is based on various genetic sites that influence the manifestation of characteristics such as musicality, disease risk, or intelligence. The study revealed that Beethoven’s rhythmic heritage was weaker than expected, despite his musical genius.

Comparisons were made between Beethoven’s rhythm sense polygenic sum and thousands of individuals currently alive. Surprisingly, Beethoven’s genetic makeup did not strongly predict musical abilities or inclinations. This challenges the notion that genetic testing can reliably determine a child’s talent in music or other areas. Fisher emphasizes the need for skepticism towards claims that genetic tests can accurately predict abilities or talents.

The study’s findings have broader implications, as discussions about using polygenic sum variables in embryo screening are ongoing. Parents may seek to select embryos with genes that predict intelligence or other desirable traits. However, the study suggests that current genetic sum variables do not guarantee the fulfillment of these desires, as there are limitations to predicting outcomes based on genetic factors alone.

While genetic factors play a role in musicality, the polygenic sum of following rhythm only explains a small percentage of the differences in this skill. There are additional factors related to musicality that are not captured by genetic sum variables, highlighting the complexity of genetic influence on individual abilities. The study underscores the need for caution when interpreting genetic information and emphasizes the importance of considering diverse factors when predicting outcomes based on genetics.
