Hox gene are basically the controlling gene which controls the timing and growth of embryonic development with presence in every animal kingdom species.
Explanation:
The presence of Hox gene in every animal kingdom species is self explanatory to have a common link between them all, even including the humans.
The role of Hox gene is a controlling gene. It controls the time of embryonic development that is, when to start dividing and which way of division should carry on for how long. This let the deciding factor for the growth of the embryo, and comes the variation, and hence, evolutionary pattern can be sketch out. This is why the scientists feel its evidentiary value in all organisms sharing common ancestor.

What is eukaryotic ?</h3>
Eukaryotes are organisms having cells that contain a nuclear envelope around their nucleus. They are members of the Eukaryota or Eukarya class of creatures, and their name is Greek. One of the three domains of life is the Eukaryota domain; the other two domains are bacteria and archaea, both prokaryotes. The eukaryotes are now commonly thought to have originated in the Archaea or to be a sister archaea to the Asgard archaea.
According to this, there are only the two domains of life—Bacteria and Archaea—with eukaryotes included in the latter. Although eukaryotes make up a very small portion of all creatures, their total global biomass is believed to be roughly equivalent to that of prokaryotes due to their typically much bigger size.
