House Bill 291, introduced in the Missouri House of Representatives on January 23, 2013, would, if enacted, require "the equal treatment of science instruction regarding evolution and intelligent design," according to the legislature's summary of the bill.

Is a new amendment to the Missouri state constitution going to undermine the teaching of evolution in the state's public schools?

The St. Louis Beacon (January 19, 2012) shed light on Missouri's House Bill 1227, which if enacted would require "intelligent design" to be taught alongside evolution in the state's public schools.

House Bill 1276, introduced in the Missouri House of Representatives on January 11, 2012, and not yet referred to a committee, is apparently the fifth antievolution bill of 2012 — and the second in Missouri.
