Many people might think the answer to this question would be an atom, but not in life. The structures go like this from largest to smallest: Ecosystem, Community, Organism, Organ system, Organ, Tissue, Cell.
I would say the arch bridge because the Romans used it, but I'm not completely sure. Beam and pillar as used by the Egyptians.
The oldest fossils of multicellular organism are from tiny algae that lived about 1.5 billions years ago. By 600 million years ago the first multicellular animals-jellyfish-like organisms -had evolved.
