A. Many development genes thought to be specific to eumetazoans were found in sponges. B. The entire genome of sponges was found to be very different in gene diversity from the genomes of other phyla. C. Samples of the living sponge Oscarella carmela were found to be relatively unchanged from fossil sponge DNA samples. D. Most of the developmental genes found in eumetazoans are absent in the sponge Oscarella carmela. E. All of the answer choices are correct.

Genome sequencing and annotation of metabolic pathways has led to predicted interactions that can be tested by transcriptomics, proteomics, and metabolomics. These interactions between the individual products can then be linked in a predictive network and used to construct testable hypotheses. The field best suited to investigate these statements would be ________.
A. adaptive biology B. synthetic biology C. pathway-predictive biology D. systems biology
