• They are multicellular organisms.
3) The earliest eukaryotic fossils are thought to occur in rocks how old?
• 600 million years
• 1.8 billion years
• 2.5 billion years
• 3.5 billion years
4) In which geologic eon/era are the oldest eukaryotic fossils found?
• Hadean
• Archaean
• Proterozoic
• Paleozoic
• Mesozoic
• Cenozoic
5) The kingdoms of animals, fungi, plants and protists belong to which domain?
