Comparative genomics research by the National Human Genome Research Institute (NHGRI) established that humans and bananas share roughly 60% of their protein-coding genes. This shared DNA reflects fundamental biological heritage: all eukaryotic life shares conserved cellular machinery tracing back over 1.5 billion years to our last common unicellular ancestor. These shared genes encode universal housekeeping enzymes responsible for DNA replication, oxygen transport, cellular respiration, and protein synthesis.
