I watched the Rise of the Planet of the Apes  trailer (which pretty much gave away most of the movie). I sincerely hope you all know that this is all part of the reboot of the old Planet of the Apes  film. And guess what I noticed?
Check out the trailer here. The first handful of words spoken include "gene therapy" hahahahaha.
If you will recall from the original film, that ending strongly hints that humanity ended due to what? Nuclear war.
I rest my case. People in the 60s feared the atom. People in the 21st century fear the gene.
