So many new species were being discovered, it was impossible to arrange them all in a hierarchy based on relative complexity of species.
C. Over time, species evolve by adapting to their environment
Option B, Genetically altered plants could make it into the human food chain is not a reasonable concern about CRISPR-Cas9's ability to edit human cells.
Large DNA deletions at target locations caused by CRISPR/Cas9 are a significant safety concern. These substantial deletions can have a base-pair range human cells of several hundred to several thousand . It is yet unknown what process led to the formation of these significant deletions. 1) the extent to which CRISPR usage should be allowed; 2) access to CRISPR applications; and 3) if a regulatory framework (or frameworks) for clinical research involving human subjects should include all forms of human genome editing, including editing of the human cells.

I remember the mitochondria breaking down sugars to create energy.
