Detailed explanation-1: -The chimpanzee and bonobo are humans’ closest living relatives. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that’s the instruction manual for building each species.

Detailed explanation-2: -Ever since researchers sequenced the chimp genome in 2005, they have known that humans share about 99% of our DNA with chimpanzees, making them our closest living relatives.

Detailed explanation-3: -1. The chimpanzee and human genomes are strikingly similar and encode very similar proteins. The DNA sequence that can be directly compared between the two genomes is almost 99 percent identical. When DNA insertions and deletions are taken into account, humans and chimpanzees still share 96 percent sequence identity.

Detailed explanation-4: -Still, chimps are our closest living relatives-we share 98.8 percent of their DNA-and new research is continuing to shed light on just how similar we remain, promising to yield insights into the roots we both stem from.

Detailed explanation-5: -On the animal family tree, chimpanzees (Pan troglodytes) are our closest living relative. We share similar life cycles, some underlying biology and a lot of DNA-99 percent based on the sequencing of the chimp genome in 2005.
