Diversity
The homeobox genes were first found in the fruit fly Drosophila melanogaster and have subsequently been identified in many other species, from insects to reptiles and mammals.
Homeobox genes were previously only identified in bilateria but more recently cnidaria have also been found to contain homeobox domains and the "missing link" in the evolution between the two has been identified.
Homeobox genes have even been found in fungi, for example the unicellular yeasts, and in plants.

Famous quotes containing the word diversity:

“We call the intention good which is right in itself, but the action is good, not because it contains within it some good, but because it issues from a good intention. The same act may be done by the same man at different times. According to the diversity of his intention, however, this act may be at one time good, at another bad.”
—Peter Abelard (1079–1142)
“What we have to do ... is to find a way to celebrate our diversity and debate our differences without fracturing our communities.”
