No, humans do not share 50% of their DNA with bananas. The claim that humans share 50% of their DNA with bananas is a popular misconception and is not accurate.
While it is true that all living organisms on Earth share some genetic similarities due to the universal genetic code, the actual percentage of shared DNA between humans and bananas is much lower.
Humans and bananas belong to completely different kingdoms in the classification of living organisms. Humans are part of the animal kingdom (Animalia), while bananas belong to the plant kingdom (Plantae). The genetic makeup of plants and animals is quite distinct and has evolved separately over millions of years.
Humans share more genetic similarity with other animals, especially with our close relatives like chimpanzees, with whom we share around 98% of our DNA. The genetic similarity between humans and bananas is negligible compared to this.
It’s essential to be critical of the information we come across and verify facts with reliable sources to avoid spreading misconceptions.
