A human being can be made from a gene count only twice as great as that of a fly or worm. As we trace the increase of complexity from single cell creatures, through small animals like worms and flies, and up to us, what we appear to be adding is control genes. Evolution is not so much adding new genes performing wholly new functions - what it's chiefly doing is to increase the variety and subtlety of genes that control other genes. We don't understand the mechanism of transfer, and indeed it's possible that the bacteria have picked up our genes rather than the other way round - though this seems less likely. But either way it's a tremendous reminder of the unity of life, and of the fact that we don't live in a cocoon isolated from other species.
Most mutations occur in males.
It's about a two-fold difference. We have got stronger hints than before that the repeat family called Alu may play some important function. Here we are beginning to see some of the functions of the 'junk'. Exactly as one would expect the junk has a function - rather more diffuse than the hard information carried by the genes, but nevertheless functional in some way. It may help to move genes around.
