Heh, a basic "toolkit" common to all animals sequenced.
More confirmation for believing that similar "gene code" or "toolkits" were used across many species, particularly if we throw in how such goes against evolution of a simple to complex progression (rather we have the contrary of de-evolution it seems i.e., "the flies and worms").
Many of the genes in that basic "toolkit" will code for things essential to life - breakdown and metabolism of foodstuffs, respiration, all the stuff that lifeforms would quickly die without having.
Designed objects, e.g., mixed and matched from a toolkit, normally don't form a single nested hierarchy. Group the following human-designed creatures:
No one objective nested hierarchy emerges, because the designer mixed-and-matched traits. For the same reason, cars don't form a single objective nested hierarchy, because automotive designers copy and paste subunits from one car to another.
But living organisms do form a single objective nested hierarchy, based on the panoply of biological traits. So given:
the hog-nosed bats and blue whales group together first. Adding more organisms, e.g., orangutans and orange trees, continues to conform to a single nested hierarchy, which the hypothesis of common descent predicts.
