Suggested change

	These include k=21, k=31, and k=51, at a scaled of 1000. Each file is about 110 MB.
	These signature files are representative sketches of model organisms. There suggested usage is to identify and remove contamination from environmental sketches. These include k=21, k=31, and k=51, at a scaled of 1000. Each file is about 110 MB.

+These sketches are of the latest releases of a number of animal
+genomes. Among other uses, they can be used to detect host
+contamination in microbial metagenomes.

Also, would you like to add some of the more canonical organisms? Namely,

1. rat https://www.ncbi.nlm.nih.gov/datasets/taxonomy/10116/
2. xenopus https://www.ncbi.nlm.nih.gov/datasets/taxonomy/8355/
3. zebrafish https://www.ncbi.nlm.nih.gov/datasets/taxonomy/7955/
4. drosophila https://ncbi.nlm.nih.gov/datasets/taxonomy/7227/
5. c. elegans https://www.ncbi.nlm.nih.gov/datasets/taxonomy/6239/

No, I just want to merge ;).

I've added these to #2717 so we don't lose the suggestion. But the pipeline I'm using doesn't do anything fancy and I don't want to piecemeal add new genomes (because it's work, and it's also error prone ;) until we automated the process more.
