: '''How much human DNA makes up our body?'''
: '''How much human DNA makes up our body?'''


: Incorporation of outside genetic material happened more than once. When the human genome was [[wp:DNA_sequencing|sequenced]] on a  [[wp:Human_Genome_Project|large scale]], only 1.4% was found to encode our ''building material'' - the proteins; the rest appeared to be "junk" DNA. Today we know that 8.5% are old retroviruses (HERVs). -- This brings Agent Smith from the movie Matrix into mind when [https://youtu.be/JrBdYmStZJ4?t=117 he classified humans as a virus] because of certain similarities: according to him, humans replicated unchecked, consumed all resources, and spread to a new area (host) when another area ran out of resources. Now he would have genetic proof, you might think: our DNA is more "virus" than "human". -- Well, the old retroviruses are almost all defective so they don't matter much. Also, noncoding but function-holding RNA and regulatory sequences - ''tools'' and ''building instructions'' - have been identified from the junk now. So, yes, no need to panic, we are still human enough.
