Do we have alien genes in our human DNA? Could this be the ultimate proof of alien life? According to a team of researchers working at the Human Genome Project, this appears to be the case. The team believes that more than 95% of the non-coding sequences (also called junk DNA) found in human DNA is actually the genetic codes of alien lifeforms. These sequences are actually found in all lifeforms found on Earth but they make up a larger portion of the human genome than in any other species known. It is these sequences that the team is using to explain many gaps in our understanding of how human beings have "evolved" over the ages.
