Genome Prairie Example: Species bias


Embryophytes (land plants) - Most plant database entries are from the land plants.

Embryophyte Tree

Spermatopsida (seed plants) - Most of the land plants studied are seed plants

Spermatopsida tree
 
Note: Trees from Tree of Life (http://tolweb.org). These trees are pending review.

The whole point of this example is to emphasize that not only do biases exist, but the extreme degree to which databases may misrepresent distributions of real things in real populations.
