All the organisms described above have some similarity to human DNA, some are more similar, while others are less. This reveals a lot about our ancestry and biological evolution over the years.
The chimpanzee and the mice are the animals listed above that have the DNA most similar to human DNA. The chimpanzee, being a primate, just like the human being, presents 96% of its DNA similar to the human DNa. The mice, in turn, have DNA with approximately 85% similarity with the DNA of humans.
In contrast, 60% of the DNA of the fly is similar to that of humans and about 11% of the DNA of plants is similar to the DNA of humans.
