The human genome has a lot of foreign DNA scattered throughout the genome, including transposons. These transposons are genetic elements that can move from one location to another within the genome, often leading to genetic variability. While some of the transposons can have harmful effects, many of them are harmless and have played a role in the evolution of the human genome.
