Austrian monk, gregor mendel, discovered how genes worked. Mendel sent darwin his paper, but darwin never read it! Genes strive to ensure that copies of themselves survive and replicate. You have the genes you do not because they lead to traits that will make you happy but because they lead to traits that have helped them to reproduce. Individuals die but genes can live forever.
