Between around 664BC and 250AD, it was common practice in ancient Egypt to offer the ibis birds as sacrifice to the god Thoth, and subsequently mummify them. In ancient sites across Egypt, these mummified birds are stacked floor to ceiling along kilometers of catacombs, totaling many millions of birds. However, how the Egyptians got access to so many birds has been a mystery; some ancient texts indicate that long-term farming and domestication may have been employed.
Which of the following, if true, most strongly suggests that the ancient texts may have been right after all?
A. Recent studies found that the genetic diversity of mummified Ibises within and between catacombs was similar to that of modern wild populations.
B. Dating back to 3000 years ago, paintings of the sacred ibises being offered as sacrifice have been found in many caves scattered across what was ancient Egypt.
C. Animal husbandry was one of the primary occupations of the ancient Egyptians between 650 BC and 200 AD.
D. Studies of DNA collected from 40 mummified Ibis specimens dating to 2500 years ago found the genetic diversity to be low, indicating interbreeding of restricted populations.
E. From studies on ancient fossils dated 4000 years ago, scientists have identified that many species of birds bred significantly more slowly in captivity than in the wild.
