Research conclusions seem unjustified. (Score 1)

The researchers remove a gene, the poor guy dies, and they conclude the gene is necesary for life?

This is bad logic. If you remove the genes that make a humans brain function, the person dies (or worse, becomes a M$ programmer). All they have shown is that these genes are necesary in this particular configuration, not in all life.

It is interseting though that in such a simple DNA structure, 100 genes remain to be identified. Life is quite complex.
