University Of Cincinnati Geologists Analyzes Evolutionary Impact Of Mass Extinctions

ests an alternative explanation.

"Many deposit-feeders favor muddy, nutrient-rich sediments as a substrate to occupy. Just such sediments were provided during key intervals as a consequence of eroding areas uplifted during mountain-building. Quite apart from the action of the bulldozers, many of the incumbent immobile types would not have liked this kind of habitat.

So I am suggesting, as an alternative to the above 'competitive' scenario, that the transition happened because of major, physical changes to habitats."

In fact, previous research reported by Miller and others on the Ordovician Period showed that diversification of certain groups was favored in areas where active mountain-building took place.

As for those who argue that mass extinctions are actually minor contributors to global diversity patterns, Miller has used his database of Ordovician fossil occurrences to demonstrate that regional and local bursts of diversification occur at different times around the world.

Over time, the bursts add up to present what Miller believes is a misleading picture of diversification trends a smooth, gradual change over geologic time.

"The global pattern does not match any localized pattern," said Miller. "The global diversity trend is misleading for what it says about the rates of transition and perhaps even for what causes them."

Miller's research is supported by NASA's Program on Exobiology.
