## Which animals do humans share DNA with?

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.

## How much DNA do we share with dogs?

Chimpanzees are our closest relative as a species and we share at least 98% of our genome with them. Our feline friends share 90% of homologous genes with us, with dogs it is 82%, 80% with cows, 69% with rats and 67% with mice [1]. Human and chimpanzee DNA is so similar because the two species are so closely related.

## How much DNA do humans share with crocodiles?

The DNA in alligators, crocodiles and gharials is about 93 percent identical across the genome. By comparison, a human shares about 93 percent of his or her DNA with a macaque. A Texas Tech University biologist led a team of more than 50 scientists who mapped the genomes of three crocodilians.

## How much DNA do we share with a shark?

It’s not just history linking us together, it’s DNA too. At least one shark species carries several genes that are almost identical to those found in humans. Researchers have identified that 154 genes in humans have comparable matches in elephant sharks, mice, and dogs.

## How much DNA do we share with platypus?

Sequencing of the platypus genome reveals that the platypus has about 18,000 genes; humans, by comparison, have somewhere around 20,000. Moreover, roughly 82% of the platypus’s genes are shared between monotremes, marsupials, eutherians, birds, and reptiles.

## How much DNA do humans share with daffodils?

Science. Humans share 35 per cent of their DNA with daffodils.

## How much DNA do we share with cows?

Cows and humans do indeed share 80% of their DNA, the building block of all life on earth, according to this 2009 study in the journal Science. But humans are genetically closer to a host of species than they are to cows, including cats, dogs, horses, and our closest relatives, apes.
