B. Two or more samples
we accidentally swapped, causing confusion.
C. A virus contaminated
the reaction in which the probe was made.
D. The human genome
might contain at least one viral gene.
The answer is D. This means that the viral DNA inserted itself
in the human tissue DNA aand became a prophage. A prophage is a latent form of
viral infection where the inserted viral DNA has no interference with the host
cell biochemical processes. The prophage will be present in the daughter cells
of the host cells.

Answer:
The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.
Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
