Senate Bill 893 (PDF), filed in the Tennessee Senate on February 16, 2011, is the seventh antievolution bill introduced in a state legislature in 2011, and the second introduced in Tennessee. The bill would, if enacted, would require state and local educational authorities to "assist teachers to find effective ways to present the science curriculum as it addresses scientific controversies" and permit teachers to "help students understand, analyze, critique, and review in an objective manner the scientific strengths and scientific weaknesses of existing scientific theories covered in the course being taught." The only examples provided of "controversial" theories are "biological evolution, the chemical origins of life, global warming, and human cloning." The sole sponsor of SB 893 is Bo Watson (R-District 11). SB 893 is identical to HB 368, which was introduced in the Tennessee House of Representatives on February 9, 2011, and is scheduled for a hearing in a subcommittee of the House Education Committee on February 23, 2011.
