In general, however, the overall conclusion is that most genes would share about 98.5 percent similarity. The actual protein sequences encoded by these genes would then typically be slightly more similar to one another, because many of the mutations in the DNA are “silent” and are not reflected in the protein sequence.
What animals have similar DNA to humans?
Humans are most closely related to the great apes of the family Hominidae. This family includes orangutans, chimpanzees, gorillas, and bonobos. Of the great apes, humans share 98.8 percent of their DNA with bonobos and chimpanzees. Humans and gorillas share 98.4 percent of their DNA.
While orangutans and gorillas are in the great ape family, humans are most closely related to two other species in the family: bonobos and chimpanzees.
Throughout studies, geneticists have found that the human genome and the dolphin genome are basically the same. Texas A&M Scientist Dr. David Busbee explains, “It’s just that there are a few chromosomal rearrangements that have changed the way the genetic material is put together.”
The lifespan of a dolphin depends on the environment and the kind of species, though the average age is between 15 and 16 years. Some bottlenose dolphins can live up to 40 years, which translates into about 100 for humans.

Do dolphins and humans have a common ancestor?
The last common ancestor of humans and chimps lived some six million years ago. By comparison cetaceans such as dolphins split off from the rest of the mammal lineage about 55 million years ago, and they and primates haven’t shared an ancestor for 95 million years.
