Does "the board has come down squarely on the side of the scientific community" mean "the board has begun to support the side of the scientific community"?
Context:
In 2009, the Texas Board of Education approved new standards for the science curriculum in the second-largest U.S. state that made a concession to each side in the debate. While the board removed a clause requiring teachers to address the “strengths and weaknesses” of scientific theories such as evolution, it added language instructing teachers to examine “all sides of scientific evidence.” But since then,
the board has come down squarely on the side of the scientific community. First, it voted to approve lessons teaching the principles of evolution. And in December 2013, the board approved a biology textbook that presents evolution as the only explanation for the development of life on earth, despite the objections of religious conservatives.
