A gene has been discovered in the genome of a eukaryote that is identical to a gene of a bacterium that the eukaryote normally engulfs and digests. This is probably due to
A. a mutation of an existing gene in the eukaryote that coindcidentally is the same as the bacterial gene.
B. horizontal evolution.
C. horizontal gene transfer.
D. a mutation of an existing gene in the eukaryote that coindcidentally is the same as the bacterial gene and vertical evolution are correct.
E. endocytosis of the bacterium by the eukaryote and insertion of bacterial DNA into the eukaryotic DNA; resulting in vertical evolution.
