<span>Answer:
At first, the Earth's surface was for the most part liquid shake that steadily cooled through the radiation of warmth into space. The antiquated environment was made for the most part out of water (H2O), carbon dioxide (CO2) and monoxide (CO), sub-atomic nitrogen (N2) and sub-atomic hydrogen (H2), and hydrogen chloride (HCl) outgassed from liquid shake, with just hints of receptive sub-atomic oxygen (O2). This hot air was rich with water discharged from hydrated minerals and cometary impactors (David Shiga, New Scientist, November 5, 2010; and de Leeuw et al, 2010). As the Earth kept on cooling from Years 0.1 to 0.3 billion, an exuberant rain fell that swung to steam after hitting the still hot surface, at that point superheated water, lastly gathered into hot or warm oceans and seas above and around cooling crustal shake leaving dregs. Now and again, be that as it may, an extensive space rock or comet would strike the planet which remelted crustal shake and transformed seas once again into hot fog. In the end, a stable rough outside layer may have created between Years 0.2 and 0.4 billion (see J. Bret Bennington's exchange of reused zircons (precious stones of zirconium silicate) from the stones of western Australia in the Hadean Eon and the January 11, 2001 declaration of zircons discovered north of Perth that give off an impression of being 4.4 billion years of age), secured and encompassed by soupy water that was at that point rich with natural mixes from interstellar space.</span>

The given statistics indicate the comparison of the genome of the various organisms. Genome can be defined as the complete set of the genetic material (chromosomes/genes) present in the cell of an organism, or, the haploid set of the chromosomes which are present in an organism's gamete cell. Since, the given statistics are comparing the percentage of the genetic material which is similar among different organisms, the blank can be filled with 'genome'.
