Comparative genomics studies of mammalian genomes suggest that approximately 5% of the human genome has been conserved by evolution since the divergence of extant lineages approximately 200 million years ago, containing the vast majority of genes.
Currently major groups have sequenced approximately 50 Mb of human DNA representing less than 1.5% of the 3,000 Mb genome. The estimated finish of the human genome by the year 2,000 appears quite optimistic considering that the world's large-scale sequencing capacity is approximately 100 Mb per year.
