Question

What animal is closest to human DNA?

Answer 1

It shares $99$ percent genetic similarity with its ancestor and lived between $4$ and $8$ million years ago. The only chromosomal number difference between it and humans is two.
The Hominidae family includes great apes. Orangutans, gorillas, bonobos, chimps, and humans are among the eight species that make up the family. Fossil evidence can be used to identify how closely one group is related to another, as well as phylogenetic relationships.

Complete answer:
Chimpanzees and humans share $98.7\%$ of their genome. Bonobos are also the closest relatives of humans and are closely related to chimps. Chimpanzees and humans share $99.6\%$ of their DNA.Chimpanzees and humans are thought to have shared some features. The number of their chromosomes is $48$, whereas the number of man's chromosomes is $46$.
Chimpanzees and humans share between $98.6\%$ and $99$ percent of our DNA, according to research published in $2005$. They're even closer to us than gorillas! Female chimps have a reproductive cycle that is strikingly comparable to that of humans, with the majority attaining sexual maturity shortly before or during adolescence. They have an 8-month gestation period as well.
Compared to the other great apes, gorillas and humans share approximately $96$ percent DNA, whereas orangutans and humans share approximately $97$ percent DNA, though these values vary between research.
Humans and chimps/bonobos are thought to have shared an ancestor as recently as 8 million years ago - a relatively short period of time in evolutionary perspective.

Note:
Chimpanzees are thought to be near relatives of gorillas, while Gibbons are the closest ape cousins. The orangutan was once thought to be humanity's closest ancestor; however this theory was eventually debunked. It is important to know one's chromosomal number at all times.
Humans, chimps, and other primates such as orangutans, gorillas, and bonobos are all members of the Hominid family. Chimpanzees have a closer relationship with humans than other hominids. DNA data acquired from both animals supports this theory.
