Researchers have noted that ants arrange their dead using the same principles thought to produce the markings on animal skin and on tropical sea shells, a first clear example of so-called Turing patterns in higher organisms.Line Turing argued that activation occurs through a feedback process that amplifies(5) small variations in the concentration of one of the ingredients, while inhibition causes a concentration of activity to suppress the appearance of similar concentrations nearby. Ant graveyards are an example of a self-amplifying activation process: ants are more likely to drop a corpse on a pile than elsewhere, and because collecting bodies and adding them to a pile sweeps the(10) surrounding space clear, new cemeteries are inhibited from appearing in the vicinity of existing ones. While activator-inhibitor mechanisms have previously been proposed to explain how predators and prey distribute themselves across an ecosystem, it is the first time such a system has conclusively proven that Turing’s process operates at the level of colonies and ecosystems.
The author considers the example of the creation of ant cemeteries to be novel for which of the following reasons（） (A) Ant cemeteries exhibit elements of activation but not inhibition, a proposition formerly questioned by Turing’s theory.
(B) Ant cemeteries exhibit Turing patterns in the absence of the predator-prey system.
(C) Ant cemeteries involve self-amplification activation, as opposed to amplification from outside sources.
(D) Ants are considered a higher organism, in which Turing patterns have never previously been established.
(E) Turing’s theory has only explained the distribution of ants across the ecosystem, until now.
