Diversify, Diversify, Diversify

In response to blogger John Hawks' opinion that "genomics has come to an inflection point — organisms whose genomes are obviously of some utility, but which have not yet been subject of a whole-genome sequencing project, are getting scarce," Blogger Prof-like Substance stipulates that researchers are "running out of 'interesting' animal genomes to sequence." Otherwise, he says, "there are a ton of interesting genomes out there we have virtually no idea about." Prof-like Substances opines that genomic "discoveries in other organisms could advance the science in animals" and points to Tetrahymena as an example of why "we need to more broadly sample organisms rather than sequencing 1,000 of the same genus."
