What is "pharyngula"

n. (context biology English) The phylotypic stage of embryonic development of vertebrate animals, following the blastula, gastrula, and neurula.

The pharyngula is a stage in the embryonic development of vertebrates. At this stage, the embryos of all vertebrates are similar, having developed features typical of vertebrates, such as the beginning of a spinal cord. Named by William Ballard, the pharyngula stage follows the blastula, gastrula and neurula stages.

Pharyngula is a blog founded by PZ Myers and written by Myers, hosted on ScienceBlogs (2005–2011, in full, and 2011–present, in part) and FreeThoughtBlogs (2011–present). In 2006, the science journal Nature listed it as the top-ranked blog written by a scientist based on popularity. The blog addresses a range of topics, including Myers' academic specialty, biology. It has become particularly well known for Myers' writing style (characterized by sarcasm) and criticism of intelligent design and creationism. In 2009, Hemant Mehta ranked Pharyngula the most popular atheist blog, based on subscriber levels and other factors.
