The Tyranids Are Scavengers, Not Apex Predators

For sixty million years, nothing came for this galaxy. The Old Ones built living weapons out of whole species. The C’tan drank suns. The Aeldari remade matter for their own amusement. Every one of those ages threw out a signal that should have carried past the rim, and the dark outside stayed quiet through all of them. Then the Imperium spent ten thousand years dismantling itself, and the Great Devourer arrived.

This is the case for reading the Tyranids as opportunistic scavengers rather than apex predators. Imperial accounts have the hive fleets reaching the galactic rim solar decades before Tyran and spending that time quietly consuming worlds with no intelligent life on them, rebuilding the biomass they burned crossing the void, and only then moving against a defended one.

Covered here: the timing of the three great invasions, what the Pharos overload at Sotha actually was, Hive Fleet Tiamet and the psychic resonator on Ziaphoria, the Genestealer Brood Mind as a signal that reports biological richness, the Shadow in the Warp as a tool for cutting prey away from help, Leviathan’s deliberate course change toward Baal, and seven objections to the whole theory including two the argument cannot answer.

Sources: Lexicanum, the Warhammer 40,000 wiki, Codex: Tyranids, the Shield of Baal and Devastation of Baal material, and the Horus Heresy novel Pharos.

Where the argument goes past the sources it says so on screen. The counter-case is in Part VII, presented at full strength, and it includes the mundane explanations that would sink this reading if they hold.
