Eukaryota appears to be

s and have none of the above features. Eukaryotes represent a tiny minority of all living things; even in a human body there are 10 times more microbes than human cells. However, due to their much larger size their collective worldwide biomass is estimated at about equal to that of prokaryotes. They are considered to have first developed approximately 1.6–2.1 billion years ago.
