Why are US state legislatures bicameral?

[Badger]

Many bicameral states started with different ways to elect the chambers. In some the Senate reflected the counties, much as the US Senate reflected the states. Since the one-man-one-vote decisions of teh 1960's, the state legislative chambers were forced to to be elected on equal population ending any distinctions in that regard.

Good analysis, which tends to indicate statehouse bicameralism is an anachronism.
